I bought Pirelli, they missed the 1st place only because of wear. It was not mentioned, for the size 205/55/16 they are the only ones with rim protection

Standing water, Michelin, if you can get heat into the Bridgestone on a damp day there's a chance it would be faster but I think michelin would be the safer option
I have a set of Bridgestone Potenza RE-71RS on my Abarth 595. It's little more than a Go Kart at 995kg, but it does have 300hp through the front wheels, which causes traction issues. These tyres are night and day compared to the stock Michelin's and the Bridgestone RE003's.
Really enjoy these reviews but would really enjoy one these reviews of UHP / UUHP tires on how they perform on high performance AWD vehicles would be an interesting test compared to RWD and FWD
My dunlop sport maxx 600a tires have a lot more performance than the pilot sport 4s correct? I don't think I can go higher that a 200 tread after having these. Amazing grip and lasted over 25k miles
Hello again, I've put the 4s tyres on all 4 corner's. Instantly feel the difference turning into corner's. I haven't yet given my car a good push. Got a remap booked with Darkside development's uk. Looking forward to giving my car a good run. Many thanks again for your testing and advice 😊
The first time I bought tires, I bought no-name winters and ended up in a tree in my MR2 (has since been replaced with another MR2). This is the second time I've got to buy new tires (summers), and this time I set out to do it right. I was intimidated by the lack of hands on testing and with the wide range of tires I was starting to get overwhelmed. But thanks to finding your channel I got a nice set of asymmetric 6s on the way for my E46.
If it doesn't get below 40*F, summers will be fine and offer better performance (on average). On the other hand, all season will likely last longer and can have more than enough performance for street-only use. There's no need for summers just because you live in a hot climate.
I think the better acceleration of the street tire comes from it being front limited, i.e. the rear tires are not at their traction limit during cornering so they can put down power more.
I hated the Ps4s on my M2, I found the steering vague and I never had confidence with the car in high speed corners or fast country roads where you’re constantly putting steering inputs in. Only fitted them because all of the good reviews saying they were better than the pss that were originally fitted.
Just replaced my EcoContact 6, honestly they were horrible.. first thing I noticed how bad they were in wet driving. They are also quite loud. I would just avoid them honestly.
I have crossclimate,very good tyres with one main downside,rubber start to perish very quickly after about 3-4 years!Now the rubber on drive axle is tearing off on top sides
Are the Bridgestones unidirectional? They could be optimized for braking which is always going to more important on a track than relatively weak acceleration.
the slower acceleration could also root from the tyre deforming under load like they do on top fuel dragsters. the rim is lighter compared to the stock one, so it spins up faster, which might be fast enough to start spinning before the tyre does. therefore also maybe a mapping/diff situation. Not sure if someone already mentioned that fine content as always. keep the praise of the PS4S up, so I feel good about having them bolted to my E92 335D :) (R19, 225/255)
I have a 01 firebird formula that runs Potenza Sport and RE-71RS on two identical sets of wheels...the acceleration difference is noticable even on the street. Off the line, they both have outstanding traction. I can do a 4k clutch dump in either and dead hook. By the end of first gear, the acceleration difference is notable. You feel like you lose speed between gear changes with the RE-71RS while the Potenza Sport "glides" between shifts. You feel the difference in gear acceleration as well, particularly at higher speeds. Its gotta be the rolling resistance in my opinion. That and the weight, all the weight of the RE-71RS is on the the shoulders and the most rubber is right on the center of tread, its the furthest away from center of mass. The design is why it corners and feels so solid but its also creating the most inertia. I want to hook up a draggy and do some in gear acceleration tests to take launch and shifting out of the equation. Id also like to see how long it takes to shed speed back to back...for example going from 60mph to 20mph coasting on both tires
It’s a-shame the most popular Falken Wildpeak was not tested for myself it kind of makes the test useless since I can’t compare to the most popular tire in the class.
You get higher acceleration at lower speeds and while in lower gears, so with the PS4S giving you less speed mid corner combined with the staggered setup allowing you to apply full throttle earlier than the square setup, maybe you see a higher peak rate of acceleration.
Did you notice a width difference? Some manufactures make the tread wider on the shoulders which make the tires wider than other tires of the same size. Anyone lnows for both these?
I would have loved to see this with the ExtremeContact Sport 02, as well. I'm partial to the Continentals, having run Michelin in the past, so I'm curious to see how you would compare them in this scenario.
I'm surprised not to see much more wear on the outside of the front tires if you're still on 100% stock suspension with little camber. My F87 M2 wore incredibly quickly without extra camber.
I think rolling resistance could play a factor. Was there a difference in peak speed on corner exit that corrolates? I would think not based on lap times. I would also say a slight change in manifold density from having to wait on the front axle could drop IAT just enough to affect peak speed. A slight taper before the braking zone? Do you have graphs you can overlay? You'll find where the difference is coming from. Driver confidence and fluidity would be a factor, but being so well versed with track testing, i doubt thats a factor here.
Personally the PS4S didn't last long for me and felt terrible compared to my Hankook RS4s on my E46 M3. I chunked the shoulders of two front PS4S in two days on track, and another set of fronts lasted in three days (225/255 stock setup on 19"). I couldn't get more than 3-4 laps at intermediate HPDE pace out of them before they overheated and got greasy. Not fun to spend half of each 25 minute session babying the tires even with proper pressures and camber. Sidewall was too soft leading to vague steering input and feedback. They're very good on the brakes though. Meanwhile I've gotten 12 days out of my front RS4s so far (255/255 17") at advanced group pace, where they remain consistent and have great feedback through the day even when hot.
Are the 71RS still super noisy? I had a set of previous 71R tires and wow were they loud. Over certain pavement they sounded like velcro tearing apart.
Hope to see you at umc. I'll be there next weekend coaching at the next nasa event, then the following month racing outerloop. Let me know if you'd like to get faster. I'd be happy to help! Haven't done ton of east course driving. Last time there I took my wife's 2020 bmw m340i xdrive with Firestone indy 500 square setup 235 45 18 to east course. It was 2 years ago in August as a nasa event and went a 1:44.2. It's 4225 lbs in race trim. Has 385 hp at the flywheel and no camber. There was nothing to compare too at the time.
