BIGGEST TIRE ON A COLORADO ZR2: NO TRIMMING 

Thanks for the feedback. I really appreciate you taking the time. I agree, that the 80 series are overlooked. They do allow for more articulation and most people have the initial intention of going higher but always opt for the 285/70r17. Again, thanks for watching.

Thanks for the feedback David. We really appreciate it. Glad to hear it helped you out. Congrats on your zr2. They’re really awesome trucks. Thanks for watching

Glad it made you laugh

It was hilarious

Glad to hear you got something out of it. Thanks for watching Jaime

Did you ever end up putting these on your Bison? About to order some for mine.

@@5herko nope. Ended up getting rid of my Bison. Sorry😕

Haha, thanks brother

Glad to hear you’ll be getting 33s. Thanks again for watching.

Thanks for watching Tim. I really like the look of 18” wheels. I already get nervous that we’re going to scratch these 17s when we cross through rivers here lol. I’m doing some shopping around for wheels but that’s going to be a while now. Do you have pics on Instagram or any forums?

I do love the 18 inch wheels

Congrats on the new purchase. Thanks for the support and feedback. I really appreciate it.

How much you paid before tax etc if you don’t mind me asking?

@@JG-mg3if hasn’t gotten here yet! Should be here middle of September. Sticker price was about 47,000, sales tax in WA state is 8.5%, but hoping to get some dealer incentives and I have 1,000 off Costco cash on chevys

@@JG-mg3if we paid $44,000 new here in Alaska. There’s no tax here.

@@bobsagit10 Thanks guys. Falling in love for the zr2 baby max. This fall may be the season for her to be in my garage..

We really like the combo as well. Congrats on your purchase of your zr2. We love the truck. Thanks for watching

Thanks for watching. Glad to help

Nice, I think you’ll be able to squeeze the 275 in there with no issues. Those are all good tire choices. I didn’t care for the dura trac as much as I thought. They were hyped up so much but didn’t really live up to my expectations.

Glad you liked it buddy

Very cool

Congrats on the purchase. I love the front end updates on the 2021s. We put 265/70r17 winter tires on here in Alaska. After leveling, I couldn’t bring myself to put the stock tires back on lol. KO2s are such a good all around tire. Smart choice. Thanks for watching Jason.

@@DustinFaddis right on man. I hear you I live new England. What a difference tire a little bit bigger tires make to look of the truck. Keep the good videos.

@@jasonlewis6914 thanks for the feedback

So I'm assuming you're still on stock rims 17x8, with 33 offset?

@@theoriginalfuzzlemutt7526 no I have new aftermarket wheels 17.8.5 +20 offset. So basically stock size

I’ll be looking forward to the pics on Colorado fans. 😆 thanks

The ko3s are a great tire as well. Those are 589 fabrication rock slider steps. You just bolt them right on. We had them powder coated to match. They’re a great addition we’re happy with them. Thanks for watching

Thanks for the feedback. We really appreciate it.

I don’t feel the leveling kit is 100% necessary with these tires unless you’re planning to fully flex it off-road. However. I do think that for just over $100 bucks… the truck looks way better with this 1.25” kit installed. It still leaves just a slight rake. Thanks for watching. We appreciate the feedback and the question.

@@DustinFaddis do you think they fit on there to street drive to the lift to put the level kit in haha?

@@yermoffroad yeah, I think they will fit for just street driving until you put the level on … just no jumping speed bumps 😆

@@DustinFaddis haha great! I have to mount them 40 miles (hiway) away from heated garage that I'm doing the install in

@@yermoffroad that shouldn’t be an issue haha

Thanks for watching Mike. I appreciate the feedback.

Glad it helped Tony. Thanks for watching and taking the time to leave a comment

Sorry my friend. I’ve recently retired from the army and have been busy starting my next career. I hope to start making more videos soon. Thanks for standing by

Thanks for watching. I’ll check this spring off these tires will fit under the truck

@@DustinFaddis also interested if this configuration will fit in stock spare location. :)

Haha... thanks man

That outfit was great

I love the humor

Yes it was

Great question. We haven’t noticed a difference in braking or and just a slight difference in acceleration. Nothing that can’t be fixed with a tune. Haha

Thanks, I appreciate the feedback. Glad I could help.

Thanks for watching Rob. We appreciate it.

I appreciate the feedback. Thanks for watching

Great question. A lot of people say you don’t buy a truck like this for gas mileage, which is true... but, you definitely don’t want to ruin the gas mileage either. Real world, in town I get 14mpg. When my wife drives she gets 16.5mpg So what that really means to me is that the more conservative you drive the less it will affect you. I used to get around 15mpg before the tires. We have seen little to no change when my wife drives. I hope that helps and I didn’t start rambling 😆 thanks for watching.

@@DustinFaddis Thanks I'm debating on making the move up and this helps.

@@aarona1409 no problem glad I could help

Thanks for watching. I’m glad you got something out of it.

Glad to help out. Good to hear you got something out of it

Lots of armor all... lol. I appreciate the feedback on the drone shots. Nobody has ever told me I sound like him 🤔 thanks again for watching.

I’ve had good luck with nitto

Did you ever figure it out? ive been trying to find them all night since I found my dad's old zr2 rock slides fit my stock colorado lol. Edit: Nevermind, I scrolled a little further and found his answer to someone else, if youre still looking he said 589 fabrication is where he got them!

I appreciate the feedback. I have not noticed a traction loss. The width difference from stock is only 1 centimeter total. As for how they look. The useable tread is a centimeter less but the tire sidewall has thicker tread so they look just as wide as the stock tires. I hope this helps. Thanks for watching.

@@DustinFaddis - I wonder if this size would mount okay on my 2021 AT4 Canyon. I wouldn’t mind leveling it. Just, I like it as stock at least until I get some miles on it. I tried looking at upgrading shocks, but the pandemic made for shipping disruptions. I am 66 now an really scope-out terrain before getting in to a bad situation. Its a fun truck in stock form, I call it my Subaru with a low range just for giggles. I doubt I even install skids under it I’m that careful. Maybe when economy returned to normal.

@@garbinator09 definitely would not. The at4 only has an extra 1.25" of clearance over a stock Colorado or canyon. The zr2 is an extra 2.25". And the 255 width tire needs a 1" level lift on top of the extra clearance a zr2 gives.

@@mikealasmar3818 - Thank you understood. Guess it’ll stay stock.

Those are bolt on rock slider steps. They’re from 589 fabrication. It gives a little more space to step on. I think they look good when powder coated to match.

Thanks for watching Rob. Glad you enjoyed the video. Is your truck still stock?

We haven’t noticed a difference in fuel economy on the highway. There’s probably a difference in city mpg but it’s less than .5 mpg. I feel that because the tire is slightly skinnier you save a tiny bit of weight and rolling resistance so the short answer is no we haven’t noticed a difference that would make us want to regear the truck. Regearing is always great for torque and off-roading but definitely not required. We’ve even towed Max weight of 5,000 lbs and it was still better than a Tacoma that I used to have. The speedometer is progressive so you have about a 1mph difference at around 20mph and at 70mph it will be off about 5mph. Just know that if you go exactly the speed limit you’re already doing your 5mph over on the highway. You can have it recalibrated if you want but again it’s not necessary. Hope this helps. Thanks for watching Dan

Nice that’s good to hear. Do you get any rubbing at full flex? Also did you do anything to the cut edge of your fender to prevent rust for long term? Being up here in Alaska they put a lot of corrosive stuff on the roads in the late winter and spring. Thanks for watching Steven.

@@DustinFaddis No rub at full flex. I used brush on rustoleum on the trimmed sheet metal. My new tires are 52lbs, didn't notice any change in acceleration, a bit more brake pedal at low speed. The E rated rides stiffer, I run 34psi (hot) from the chalk test for contact pattern.

@@madcratebuilder sounds like you've got a great setup. Wildpeaks are great tires. I agree that E rated tires definitely make the ride a little stiffer. Are you on Instagram?

I would recommend the level. They’re super cheap. Now for the ready lift one we used they’re on Amazon for like $115. If you check out our Level video there’s a link to the exact part. It can be done in your garage with basic hand tools. My wife and I knocked it out in under two hours while filming the process. Thanks for watching and thanks for the feedback

Congrats on the bison by the way

Perfect then i will take a look at that thanks man!

😆 that's how I picture someone dressing that gets all butthurt about new guys asking questions online haha. Thanks for watching.

I think the leveling kits are all made well and they’re so simple it doesn’t matter. Just stick with the 1.25

Thanks man. I appreciate it.

Glad you liked it Brandon. Thanks for watching

You’re welcome

Thanks for watching Shelley. That is a step that bolts onto the stock rock sliders. We picked it up at 589 fabrication. I talk about it a little in another video while going over the mods we’ve done.

Here’s the other video. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-oJdC_b6m7_Y.html

If you don't have the highmark flares you'll have the same clearance. Minus a little up front due to the bison front bumper. The front will not matter though. There's plenty of room. I hope this helps. Thanks for watching.

KO2s are definitely a solid go to. Thanks for watching Shannon. We appreciate the support.

Thanks for the feedback. I’ve seen that a lot on Facebook. I tried to flex it as much as I could. There was a few times that it got extremely close but never touched. I was taking it easy though. I could see if you go through some huge ruts real fast or really beating the crap out of the truck it’s possible it could rub. So the short answer is… mine doesn’t rub. But if you’re slamming it around off-road it is possible. 😆 thanks for watching. We appreciate the support.

@@DustinFaddis Thanks for the response! I can only find 255/80 in an E-load range. Would you say you experienced any significant declines in ride comfort, engine performance, and/or MPG? I’d love to get the Wildpeak AT3w tires in that size but I’m hesitant to put E rated tires on such a light truck.

@@stingrayray3413 I E load range on my truck and it still drives great. I’ve noticed a slight decrease in acceleration. And no significant mileage change. I haven’t noticed a change in ride comfort.

@@stingrayray3413 id check overall tire weight and go with the lightest tire. At least one of the lightest tires so it won’t change engine performance or mpg.

Glad it was helpful Damon. I just added a link to the ready lift leveling kit that we used from Amazon. It’s in the description. They have a great build quality and they’re pretty inexpensive. Currently they’re running about $115. Thanks again for watching.

The mud flaps are weather tech. They’re great quality but again they’re mud flaps so not real cool. They have really helped keeping mud and rocks off the truck. Well reduced anyway haha. Thanks for the feedback. We appreciate it.

Have the same mud flaps on my 19' ZR2. They work great and screw into factory holes so no drilling new holes required. I'm gonna have to look into the rock slider steps for the wife

@@justkillintime7554 I agree, the mud flaps are made really well and fit perfect. My wife loves the steps. I was going to paint then black but the wife wanted them powder coated to Color match. She was right I think they look great like that.

They’re 589 fabrication rock slider steps. They shipped to us bare metal and we powder coated them to match

I’ll be tiring to stuff one of these tires up in the spare tire location shortly

Glad you liked the video

@@DustinFaddis thanks, it would be nice to know although I think I really want to get a hitch tire carrier and get the tire out from underneath. Thanks to your videos my want list has gotten even longer 😆

@@meltaylor1374 haha, glad to help with your list Mel

Walter, that’s a great question. I feel that they look better than they function for everyday use. What I mean is, when it’s icy out or muddy, you can actually step up on it. Or if you change the way you get in and out of the truck it works well. That being said, if you’re wearing nice clothes and try to step out on the ground then your pants get dirty because the step sticks out. All that being said, we actually like them

Those are the rock slider steps from 589 fabrication. I talk about them a little in this video below. I had them powder coated to match. I really think that makes it. I think we’re currently the only zr2 that has them color matched. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-oJdC_b6m7_Y.html

I love the orange crush. Thanks for the feedback

Thanks For the feedback David. I’m glad to hear you got some value from the video. I’ll definitely check out that rack. I’m stuck trying to decide the next mod or upgrade.

No problem, glad to hear you got something out of it.

@@DustinFaddis just bought a 2022 colorado zr2 bison diesel

Had an 18 loved it what's those things on your rock sliders looks step like my dear wife belly aches about its hard to get in.

@@larryburrow6278 congrats on the purchase. How are you liking the diesel? I just did a video on installing an XXL fuel tank on my Ram truck. I was wanting to do it on my zr2 to extend the range but they don’t make gas tanks… only diesel 😔

@@DustinFaddis my 18 was diesel it got after 30000 miles 26 putting and over 29 on trips I just love that diesel

That would definitely help. I have the blocks but I just haven’t gotten around to installing them yet

Thank you

@@janpayne964 anytime

Check 589 fabrication

I would take a look at the 265/70 r18

Alright thank you

Thanks Justin. Well it depends on exactly what you mean by ground clearance. The front bumper is up over 3 inches. Technically the lowest part of the truck. “The rear axle” , only raises as much as the tire that you put on. This tire is over 2.5” taller maybe closer to 3” so that would make the lowest part of the truck about 1.5” higher. It doesn’t seem like much but your rear axle is actually a little higher with this set up than it would be with a lift and using 285/70 17 tires if that makes sense. Thanks for watching.

😆 Great selection Larry. We’re really happy with our tire selection as well. I feel it’s the perfect combo for this truck. Unless you’re going all out and lifting, cutting and regearing

We’re real happy we went this route. When off-roading the side of the truck has stayed a lot cleaner haha. Every little bit helps. The extra height helps when we cross through creeks. I think it looks great too. Are you planning to run the same setup? Thanks for watching Ron.

Yes likely go with similar setup. I don’t want to cut up my fenders. I have enjoyed the GY Wrangler Duratracs tires for wear, traction and noise. Are the Coopers noisy on hwy?

@@ronpoirier41 I didn’t want to cut my fender either. At least while it’s this new. The Coopers are noisier at hwy speed but that’s due to their more aggressive tread pattern.

There are definitely lots of factors that go into it…. Like you said, bfgs run small. They’re like shoes. You can’t just go by size 😆 thanks for watching Karl

@Jason Yang depends on the tire. BFGs run small.

@Jason Yang these are all good questions Jason. Sorry didn’t cover more on the video. I just didn’t want it going like 30 minutes or more trying to cover all possibilities. Just like Karl said, some manufactures or brands run small. BFG is one of those brands.

@Jason Yang sounds good. You’ll have to post some pics. Are you on Instagram?

@Jason Yang Cooper makes a fine tire. What type of terrain do you wheel in?

You’re right estevan. The zr2 has slightly flared fenders. And the z71 has a bumper that might get in the way. I’d look at 255/ 75 17 or 265/ 70 17 if you want zero rubbing at full flex

So, unfortunately I believe that they will rub. The zr2 has wider fenders and a 2” lift from stock. I think that you would have to add a 3” to comfortably fit them. That could still leave you with a little trimming. There are some nice lifts out there if you’re ready to go all out

@@DustinFaddis yeah I had a feeling it would be a little much, might just go ahead and stick to the 265/65s for now, sounds like maybe 265/70 for the KO2s as the sore lugs don’t stick out too far. Thanks for the quick response!

@@ballpython365 no problem, anytime

Thanks for watching Mark. A 265/80 17 would definitely rub on the front of the rear fender at full flex. I’m not sure the difference in size would be worth worrying about. I believe it would clear up front without issues. Surprisingly each truck is slightly different. I’ve seen 2 zr2 trucks with the same tire and size… on one truck it rubbed slightly the other truck it didn’t.

I haven’t tested that yet but I will as soon as we get our snow tires removed

Yes. Mentioned a few times in comments he is only running 1 1/2 level up front and likely don't need it as he had not rubbed, but got close to rubbing on back tire.

Thanks

And thanks for watching

I think if you add a 3” lift the tires should fit. The zr2 has a 2” factory lift and I added a 1.25” spacer. I think you should have room

We used the ready lift kit. It’s a 1.25” level. We really like it. It was made really well, the quality is great. It gives perfect clearance for our set up. If you look at the description there’s a Amazon link to the same ready lift kit that we used. It’s perfect height without worrying about throwing your axle angles off

@@DustinFaddis great thank you very much.

Looks like cooper has the same tire in 255/75/17 as well ( still a pizza cutter). Does that (75) in stead (80) make the over all diameter a 32 inch in stead of a 33 inch. I can't seem to find the diameter specs on tire rack. I am just trying to figure out if that (75) side wall will help slightly with any potential rubbing? Load rating is a C instead of an E .Again thank you for this video and information. Shoot I found it, Yes the difference between the 75 and the 80 is i inch in diameter.

@@MrRyanmcmahon you’re correct. That will make the tire a 32” from what I see it’s 32.06. That being said. Each tire manufacturer builds the exact same tire size slightly different. So if you’re going with a 32 I’d go with the largest 32 you can find. Otherwise, as soon as you put some miles on you’ll be in the 31” range. Hope this helps

Thanks for watching Curtis. When we took the truck out and flexed it as much as we could, the tires were nowhere near rubbing in the front. So I can imagine that they would rub much without the 1.25” level. Especially if you’re not flexing off-road. Are you still running stock rims?

@@DustinFaddis The truck hasn't arrived yet, but I will be running the stock bison rims. Thanks for the quick reply

@@curtisknott congrats on the purchase. We looked for a bison but couldn’t find one up here in Alaska

Great question. I’ve actually been unable to get a 5th tire up here in Alaska. Most companies are telling me that it’s unavailable to ship to my location. So I’m not sure yet. As soon as I get one I’ll post an update. I’m actually considering getting these same tires on my dually, so maybe if I buy 7 they will ship them. Thanks for watching

I haven’t even recalibrated yet. It’s only like 4mph off right now. I was just waiting until I tune it. That will be coming up soon.

@@DustinFaddis Cool. I'm curious how to do that on a '21.

@@Kovaction I’m about to order the trifecta tune. I’ve heard great things about it. I’ll post and let you know how it goes.

They are weather tech direct fit mudflaps. They actually fit perfect and don’t run with our tire setup

I think they will rub a bit. A zr2 has more open fenders and a 2” lift

@@DustinFaddis say i was to lift it, would there still be rub? or would some trimming be needed?

@@turley52 I’d say with a 2 or 3” lift you might have to slightly shave your front bumper just a touch. But that’s just a guess, I haven’t actually seen the setup in person. I’d go for it…. 6” rough country lift you’ll have no issues
