Really appreciate this review/video as I was contemplating between 18" v. 19" Martian Wheels. I'm sold on 18x7.5. The pros of styling, gained efficiency, and softer ride (more wall) has me sold.
I've been running TSW 20" wheels with Michelin sport 4S tires on my M3 since new and I'm averaging 268W per mile for almost 12,000 miles. The wheels weigh 23.75lb each. Obviously heavier than Martian 18's, but still get decent range.
New wheels look great and you're finally in the normal wh/mi relm! My recent city/highway trips about 175 miles north to Richmond in 50 degree F temps with 19" factory Tesla rims on an AWD non P at 75 mph are averaging 280 wm/mi.
The best wheel size is always the smallest that you can fit over your brakes. It always grinds my gears that so much brilliant engineering went into mastering the efficiency of this car, and they threw it all away for some big, dumb-looking 20" wheels.
@@finesupplements9698 Aero covers or not, huge wheels annihilate fuel economy and make the car ride like crap. Get the small wheels and take the covers off
@@finesupplements9698 99.9% of people who buy Teslas aren't tracking them, they are daily driving with them. Also notice time attack and rally drivers aren't fitting the biggest wheels possible, maybe your opinion doesn't hold up to reality
@@finesupplements9698 Agreed. I went with the Model Y performance and love the look of the wheels. I don’t care about squeezing some extra miles out of the range. It’s more about styling than performance (for me).
I just put on 18" Martian Wheels, after having my Model 3 Performance for one year. Much better efficiency seen now. Ride quality is much better. I put Pirelli P Zero All Season Electric (electric is part of the description) tires, in the 235/45/18 size. They look very wicked. I highly recommend these. Very pleased.
I think consumption is somewhat very close to stock aero wheels. Just put more pressure if you want to lower Wh/mi. Or custom order 18x6.5 Martian, plus 195mm tyres with like 49psi. That will be super low consumption and even lower with aero caps on.
I am curious if the smaller size has much affect on how far the car thinks you are actually going. This could affect the range and efficiency calculation the car gives. I know it’s not much, but dropping from 235 to 225 does slightly reduce the diameter of the tire too, when staying with the 45 ratio.
But did he stay with the 45 ratio? I don't think that's possible when you're dropping 2 in in total rim diameter. It would end up being like a 65 I think. but you are correct if that was not accounted for and the total tire circumference is different than it would affect the numbers. Although to get higher efficiency I would think that the Total circumference would have to be larger meaning less tire rotations than the car thinks is occurring. That would get you more miles than you actually did which would make it look more efficient than it actually is
Blair Thornton tesla Center caps can be bought from shop. Tesla.com but they are factory aero wheel grey. So if go with the black or silver wheel color they might look odd.
Look and performance of those new wheels and tires are great. Good time to be quarantined ... let's go to the tire store, visit a friend and go to starbucks??? Stay safe man.
your 18x7.5 wheels with 225/45R18 tires look great. I've asked on multiple channels and on forums, but no one knows why Tesla decided to go with a wide wheel & narrow tire combo. My wife's 2023 standard 3 comes with 18x8.5 wheels and 235/45R18 tires which have a stretched look.
@@44kas88 If the tyre circumfrence is smaller the breaking power increases. Contrary to what most people Think, tyre Width does not influence braking. If the contact area is smaller, the force Per area is higher, which cancels out, so friction remains the same, (Friction coofficient = normal force * area). However as the same amount of energy, is transfeered through less rubber, they'll Wear faster. Also narrower tyres loose grip soner cornering.
Everyone is talking about size, but no one is talking about the drag from the shape of those wheels. The M3P wheels are designed to to aerodynamic and work with the car. Personally these MW are Fugly looking compared to Replica R241’s are also on the 20.1 lb range. Changing tire size will increase body roll as well as instability at cornering at high speeds. Keep that in mind.
Great video Kyle. I was watching @DirtyTesla 's video when he got them...I happen to have the AWD LR w/the 19" wheels. Just wondering what the difference is in ride quality between them? Road noise, any bump dampening, etc. and any difference in handling? On another note, when you're looking at efficiency, I've noticed autopilot is not super efficient in comparison to when I'm driving my self. I compare it to an analog vice digital mode where when I'm driving, just because when there's a little hill, I don't mash the accelerator down to maintain that exact speed, and the car does. I wish that autopilot had a buffer where you could set a threshold like within 3-4 mph before it overreacts and applies a ton of throttle to maintain exactly the set speed. Whereas, autopilot, on a given drive will average ~290Wh. I, manually, will average ~240-260Wh. driving roughly the same speed. So oddly it's kind of become a challenge to me. Don't get me wrong I love driving the car like "I stole it," but when driving on my commute, I'll frequently find my self just seeing how efficiently I can drive the car, but still driving it somewhat normally. Keep up the videos, really enjoy watching your work!
If you installed a "minus" wheel/tire package that had a smaller overall diameter, wouldn't it change the final gearing of the Tesla motors, potentially making it accelerate quicker? Might be interesting to take a stealth P3D without the bigger red brembos and put the smallest package you can fit on it, then set a new 0-60 record. Thoughts?
Smaller tyre size also affect consumption. Whether smaller contact patch or smaller diameter, both will improve your power consumption. Adding that you have lightweight wheel, this effect is compounded
Those new wheels do look very nice, as they certainly should for ~$500 per wheel! For $2K plus shipping/tax, I could supercharge on a very long trip for less on my stock 18 " Aeros.
I am picking up my new M3P on This week. I found out that the the stock 18" rims with not fit over the performance models brake calipers so if I want to get 18" wheels I have to go with something like the Martians which are always out of stock
Mr AMG in Italy the paper that comes with the car and linked with the licence plate states the tire measure according to what the car is equipped with. Sometime we have an optional measure for winter tires only but my M3 doesn’t. Id a cop pulls me over he can stop the car, give me a tiket (1000+ dollars) and force me to go back to car omologation procedure with additional costs. And in case of accident the insurance doesn’t cover...
I think consumption somewhat very close to stock aero wheels. Just put more pressure if you want to lower Wh/mi. Or custom order 18x6.5 Martian, plus 195mm tyres with like 49psi. That will be super low consumption and even lower with aero caps on.
LOL more Sentury tires to be shredded. Thanks for the video. Will eventually be replacing my Model 3 Performance wheels with forged. For optimal battery life, never charge to full except just before starting a very long road trip, and never go below 10%. Obviously track use is different. Talking about daily driving.
@@LarryRichelli In principle 65% would be better than 80%, but overall just try to keep in in the narrowest range centered around 50%. That will maximize long term battery life. In other words, avoid extremes of charge and discharge. That all said, Tesla's battery management system does an excellent job taking care of the battery pack. But we can also help it by deliberately avoiding extremes.
@@OutofSpecMotoring good video, sorry to be on your case but social distancing with friends or someone outside of your household isn't social distancing...
People need to get a little perspective. The goal is to slow down the transmission of the disease - not prevent it. Meeting with a single friend doesn't increase transmission as much as going to the grocery store where you'll be passing by dozens of people.
Yes, the lighter weight wheels make a difference. I assume the tires are also lighter (should be). I think you also mentioned that the 18's are more narrow, thus providing a smaller profile and less drag. Also the rolling resistance of the new tires is different than the 20's....maybe more, maybe less. It depends on the rubber composition. So overall, there are a LOT of variables that influenced your most excellent consumption figure.
Did you change tire setting in Tesla menu, btw I have P3D 20" oem and my 19k mile lifetime is 293.. yesterday I was driving for 3 hours because was bored as hell, mine was 280 with no AC and temp was 70 and speed was 73mph with 5 persons
How does the overall tire diameter compare? It should be close to the original tires. The new tires are quiet. Do they have the sound absorbing foam inside? Probably not. At least potholes are less of a problem with higher profile tires.
Is that an option ?. I would have thought the outer diameter would be exactly the same. Have you noticed the small wheels have big profile tyres the big wheels have low profile tyres. Big wheel + big tyre = SUV size
@@chrisredfield3240 The outside diameters do vary slightly between the three different rim size options. There is a 0.6% difference in o.d. between the 18" and 20" wheels: 235/45R18 = 26.33" 235/40R19 = 26.40" 235/35R20 = 26.48"
Kyle, I noticed the same thing when I swapped my 20 inchers out for 18x8 inch flow formed wheels with Pirelli Pzero Nero GTs. P235 45 18. My average consumption for the first 3000 mi on the 20s was about 330 wh/mi for the 20s. Over the last 2200 mi on the 18s I've been averaging 279 wh/ mi. Make sure you switch the wheel configuration on the car to 18 or 19 inch wheels as the 20 inch wheels have a larger rolling diameter and using that configuration with smaller wheels will give you slightly optimistic consumption as they go farther per rotation. The 20s are power hungry. Tesla should offer an 18 inch performance option or modify the aeros to fit.
it doesnt really matter what the car thinks the wheels are...it only changes your estimated range which is a made up number anyway. Id suggest keep it on the 20" setting because they look better on the app/screen of the car and dont give you false hope as far as range goes. Or just change it to percent
@@rtsstreamThis is an extreme example but if you have a tire that takes 10 rotations to go one mile and another that takes 20 rotations to go one mile. You will hit one mile faster with tire #1. In the real world this amounts to the speedomter being about 2-3mph off and the odometer reporting a greater distance traveled than actual. Therefore giving an optimistic wh/mi calculation because the car hasn't actually traveled a mile with the smaller tire. The cruise and the autopilot will also be off if you set it to 80 you will only be going about 77-78 mph. Also screwing with the perception of efficency and speed. Your perceived 0-60 will also improve because it will actually be a 0-58 😂
@@Robbie6298 you do realize that the wheel size isnt the tire size. For example..I switched my 20s for 18s and I run 245/45-18 tires..which have the same circumference as the 235/35-20 tires that come stock. All of the tesla wheel options (18,19,20) are paired with tires that are about the same overall circumference..which ensures accurate speedometer no matter which wheel option you pick in you car setup. the wheel option is purely for a graphic change and a range calculation.
@@rtsstream I run a 235 45 18 my wheel diameter most closely resembles the 18 in and 19 in option. Yours with a 245 looks to be the same diameter as the 20s. Kyle is running a 225. His will be smaller than any of the options unless he went with a 50 profile tire. It's not just for range estimation. Tesla's take info off the wheel speed sensors. If you have the wrong diameter tire your speedometer and odometer will be off too. I tried both GPS verified speed most accurately matches for ME if I select the 18 or 19 inch option.
Yes please, do 55 mi/h consumption test with those wheels! Very interesting! Do you think that those wheels are more aero than aero caps on model 3? Looks like those are the same Wh/mi as stock LR wheel/tyre combo. But I bealive that 225 mm wide tyre on lighter 7.5'' rim will make consumprion drop a little especially in stop and go traffic.
those wheels are really nice! I just swapped my 20" factory wheels for a set of 18x8.5 konig hypergram. Havent been able to do any range testing yet, but the achilles I bought smoke very well :) (im expecting a range decrease since I went up to 245/45-18) ..I also got mine mounted at discount tire, they wanted $60 for each TPMS, I found a set of 4 sensors on amazon for $70 bucks and they installed them for me free when mounting the new tires/wheels.
I am looking through the comments or anywhere in the video where it is stated how much the rims weigh? He keeps saying that lightweight is key, but did I miss the actual weight? Any reduction in unsprung mass will result in better range, but it would be nice to start quantifying these reductions. I would think that as EV's become more efficient, one day we will start seeing one piece carbon fiber wheels make it to the EV market.
Hi Kyle, thanks for this awesome video. In the Min 10:44 you mentioned Aeros need to SHAVE the calipers on the front. I wonder if you have more details as to how to do this or how many millimeters you need to shave them?
Bought the same wheels, but I did not put the narrowest tires (Michelin CrossClimate 2). At 75 mph efficiency dropped from 290- 300 Wh/mi to 245-260 Wh/mi. Feels more responsive, so I might want to replace the anti-sway bar with something stiffer, but lighter. Happy with the setup so far. Originally had 19" OEM wheels with OEM Continental tires ... Wh/mi was even higher ... I was basing my efficiency using OEM 18" aero wheels with covers with winter OEM Michelin tires.
@@kit5195: Went with the 7.5 ... I think I'll install the narrow set of tires when I go on another cross-country drive or from Seattle to SoCal. I'll get less tire resistance and should get even better Wh/mi rates as long as I stick to low resistance tires.
Fantastic content. Do you think you could’ve gone with a 50 sidewall instead of 45 since you dropped down to a 225 on 7.5 width. I’m ordering the Martians in 18x7.5(because of your video) but haven’t decided on tire size yet. Would like to go with 225/50 18. Our roads are a little rough around Toronto and I think the bigger sidewall would be a plus. No rush as my wheels are back ordered till November. Thanks.
*** Important Safety Note *** There is no 225/45/R18 Tire made that meets Tesla requirement for load range! Important consideration if you want to go with these narrow wheels. You CAN put 235/45/R18 on these same wheels however that meet Teslas safety requirements
Dirty Tesla has these rims as well. Check out his YT channel for a review. Going from 20 to 18 with a light rim like this is going to increase efficiency.
Just got these on my performance. 18x8.5. America's Tire told me they didn't fit properly. Apparently there is a small gap that could eventually cause them to shake and rattle. Anyone have this problem?
Hell yes. You live like 5 mins away from me. I really want to get rid of my 20” performance tires to improve the range. I don’t know if it’s the wheels or the tires themselves that make so much of a difference. Also, did you notice an improvement in ride quality?
I like this wheel. Wonder how the range/weight savings compare to the 20” forged t sportline set. I have those on my car and the consumption went down plenty.
Do you have any pics of the stance from the rear with that skinny wheel? I also have a P3 and can't find any pictures of how the 7.5 vs. 8.5 martian wheel looks. Thanks!
I assume the car measures distance by tire rpm. If that’s the case you need to somehow tell the car you put smaller tires in it or it will skew range and even speed. Smaller tires get more “rotations per mile” appearing to the car as though you are traveling faster and hence farther per unit time
I bought the standard tire size that goes on a M3P. 235/45/18. Then in the Tesla menu, I told it about the new wheel size. I'm seeing the much better efficiency and the ride quality is noticeably improved.
I just ordered the undersize Martian 18" and a set of Nokian WR G4 225/45 R18 tires since I live where it snows a lot. Anyone who lives where it snows should check those tires out. They are all Weather tires unlike all season tires they are snow rated and have the snow flake on the side that will approve you for driving where they require snow chains or AWD with snow tires. I once got caught in the snow with my 20" with the PS 4s on, that was not fun. These Nokian's will be the best of all worlds and my daily tires. FYI Martian said they are about 3 weeks out on shipping due to COVID but it will be worth the wait, I am trying to see I have can just go pick them up, I have no patience lol
And not a word about the 0-60 time... What a shame... I have put 20 Inch on my long range dual motor and experience a significant change in 0-60. Sow the 0-60 with a m3 performance on 18" is very interesting.
There was a different video in which the different tires were tested on a Model Y, and the Martian wheels gave the best 0-60 times. That video was by A1 Tesla, I think.
Kyle I reached out to Martian and received a prompt reply they are also making a wheel for the Model X/S! They are about to make a run for the Model X!
A few points, first, contact patch from 20's to 18" is significantly less for handling and breaking and cornering speeds. Second, winter tires on larger wheels, which I have, is what the factory has designed into the P model 3's. I don't mess with factory specs as it both a plus and minus in the performance of the P3D...
Did you recalibrate the computer to account for the difference in diameter of the wheel? If you didnt, your speed and consumption will be drastically off since it will assume the diameter of the wheels was that of your 20s.
With regards to overall difference in diameter, 20" wheel + tire will equal same diameter as 18" wheel + tire if you get the 235/45/18 size. It's the second number in that that is important with regard to overall diameter.
Hi there thanks for your great videos . I was looking to ask your opinion on the Tesla 3 sr+ vs the model long range ? Or make a video about it thanks again
I believe your results may be inaccurate. What is the exact before / after tire sizes? You can’t just pick 18” wheel size from the software and have accurate speed / odometer. The setting in the software has to do with circumference of the tire technically. A skinnier tire even on the same diameter wheel is not the same circumference.
Great video! I know they are very different vehicles, but how do you compare the model 3 and the Kona ev in terms of the ride comfort? I’m considering both of them and ride quality and suspension are an important factor because of the pothole-riddled streets of Montreal... thanks!
Also the martian wheels do not have the aerodynamic advantage. There has to be more research and data to really understand whether the 18" or 19" martian wheels on MY Performance will indeed increase range and as a bonus a decrease in 0-60mph time.
I did not see you use the Tesla app to input the wheel size change. If the Tesla still thinks it is running on 20" wheels when you installed the 18" wheels, it seems the Tesla thinks it is going further than it really is and thus using less energy per mile than it really is?
I don’t think I’d put $57 tires on a powerful car. Would you feel safe if you’re flying on an airplane and the pilot says, “we have the cheapest tires on the plane, let’s hope they hold up on the landing.” Somethings are worth paying a lil’ extra for, ya know?
@@Bluelightning23 they’ll just wear faster and back to the tire store. I’d rather spend the money and get a good set. The cheap ones are basically good if you NEVER punch the acceleration so you get the most out of them. But, the weight of the car alone will wear those $57 tires real fast along with any corners. Not worth it getting something cheap for a performance vehicle.
I mean.... LR and P has the same battery. The ranged difference between LR and P is literally thanks to the smaller wheels on the LR. Of course 18'' is range increase
Thanks for the video but on the website they are out of stock and there is no option for a 7.5" option. I called them and they are not going to be selling the 7.5 anymore. Not enough people were buying it so they have discontinued it.
Hi Kyle, I will buy a Model Y performance near the end of the year. I have not heard much good about the 21 inch wheels. Will another version of these 18" wheels work well on the Model Y?
while the 20" wheels look good, unless you are using the car for racing they just don't make much sense. Tesla should really offer 18" wheels as an option for the performance model.
Nick Erickson The problem is that you have to give up the top speed increase and track mode as part of the deal. I want those things with the 18” wheels
Kyle, when will you do another test with new Martin wheels and new tires. Wondering if this wheels would do better wh/m at average 75miles speed test then 19 stock wheel. Can you do compare and show results please. Are this 18 inch 7.5 wheel traction better than 19 inch stock wheel?
Kind of amazes me that Tesla doesn't try and put the lightest possible wheel on all of their cars. When you're spending $60,000 adding an extra $1,000 for a set of nice forged lightweight wheels seems like an obvious way to get better efficiency. And I've never understood the point in 20-in wheels with tiny ass side walls you're asking for what happened to you or engineering explained. He was on a road trip and lost both right side rims and tires fracturing the rims. Cost him $3,000 to get repaired. He then did exactly what you did and bought 18 in wheels. To me the car should come with 18's or even smaller, it would increase efficiency and ride quality.
I did a 75mph range test. Same temperature and speed and didn't see a real difference. 265 wh/mi vs 270 wh/mi. In the 60mph test, they were the same as well. It's smoother with less chance of pothole damage is the only benefit. Tires are much cheaper that's a huge benefit.
