BIGGEST TIRE ON A COLORADO ZR2: NO TRIMMING

In this video you will see the tallest tire we can fit on a 2020 Colorado ZR2. Our truck is a 2020 ZR2 Dusk Edition that has been leveled with a Readylift 1.25” leveling kit. We haven’t added fender flares and we haven’t done any trimming. The video will start out going over tire sizes and what they mean. We will go on to explain load ranges, tire ply, and speed ratings. We will end the video by explaining our thought process and why we chose the tires that we did. You will also see the truck flexed near the end of the video showing how much clearance is or isn’t left. Remember: No trimming.
We hope you enjoy.

This video is so well done that I just can't say enough about it! My ZR2 is ordered so I have plenty of time to watch videos-my first mod of course with be a level and tires. I now have the clearest and best understanding of what to do! I'm coming from a full size GMC and spent countless hours doing research on height, tire and wheel combos, so your level of detail is greatly appreciated. Again, the video is awesome. Use of drone footage and photos, and great narration, I'm impressed!

[@ewertdavid9741]

Very good and correct explanation of the tire size info on the sidewall, one of very few vids where this is done correctly. Secondly, the tire weight is often overlooked as being such a huge factor on HP, and gas mileage, again very well done. Lastly, the '80' series tires are far too often overlooked and are a great option to go tall, and limit the chance of rubbing at full lock when articulated. Again excellent video, one of the better ones I have seen!

[@DustinFaddis]

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.

[@bbaaspencer1]

On my 2018 Colorado, I had 265/60-18. I installed the leveling kit and added 265/65-18 Goodyear Trailrunners. It’s the front struts you have to worry about by going wider. My next set will be either KO2, Duratrac or STMaxx 275/60-18 because I have the room. Oh, and anyone out there, your speedometer will be off. Mine is only 2 mph.

[@DustinFaddis]

I'm so glad someone has finally gone with this tire size and shared their experience. I have been curious about it since I got the truck. The one question I have for you is whether you think the leveling kit is necessary considering you said you didn't get close on the front. I have the same mud flaps and would like to keep them. Thanks for the upload!

[@DustinFaddis]

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.

[@doublejj39]

Great video. I have a bison. How much ground clearance did you gain from stock? Or maybe I missed it.

[@DustinFaddis]

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.

[@markdalern1]

Thanks for the content. Do you think you could run a 265/80/17?

[@DustinFaddis]

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.

Have been meaning to come back around on this helpful video. Thanks for all the information! Confirmed, my 2022 Bison is on 265/65 17 Wranglers. Once those wear out it just makes sense to finally give the right look and functionality to my Bison by going with the 255/80 r17 setup with the 1.25 leveling kit. Is there a preference on leveling kit? And is there a software update I need to do in order to calibrate speedometer? Again thanks - Mike

[@DustinFaddis]

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

[@matdan2s6v]

Has the taller tire affected the trucks performance or fuel economy? Is the 33" tire on the cusp of having to do a gear change? Did you have to get the speedometer recalibrated? Thanks for the excellent video,s

[@DustinFaddis]

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

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]

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.

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?

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.

Any idea if a 255/75 will fit a ZR2 without a level and no trimming?

[@meltaylor1374]

Great video, I'm new to the chevy colorado ZR2 and really love it, I assume a 33" tire won't fit in the spare tire well? After watching this I'm convinced with going with that same tire size.

[@DustinFaddis]

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

Do a best LED next. The aev 33" trim and 1.5 lift fits a 10.5x34" on my truck with oem wheels. E rated Wildpeaks.

[@DustinFaddis]

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.

[@madcratebuilder]

@@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.

[@DustinFaddis]

@@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?

Alright thank you

I don’t have the ZR2. I have the Z71 but the bed is the same. I’m eventually going to get a RETRAX POWERTRAXPRO XR TONNEAU COVER with a LEITNER DESIGNS ACS FORGED TONNEAU - RACK ONLY - Chevrolet. This bed rack can come with various mounting options including minted boxes for storage.

With no Clue of the mechanical part, was well done, but to ignore the most important part is the Gear Ratio in the Differential so wont kill the transmission also along with a broken front axel weak remote engagement.

What’s the biggest I can go with a 1.25 inch leveling kit

[@jasonyang2869]

Great video! I'm looking for a larger tire myself for my 21 zr2. I just noticed that the overall diameter of 225/80r17 DISCOVERER ST MAXX tires is 32.8 when I was doing my research and some other tires of the same size are a little over 33. Have you looked at other tire brands of the same size? Since the cooper tires are a tight fit, does it mean the other tires are likely to rub?

[@DustinFaddis]

Thanks Jason, you will have to do a little more research and look into individual brands for the 255/80 r17. You can still purchase a tire that is slightly larger. You would just have to put about 5,000 miles before fully flexing the truck. So that’s still an option of you’re really wanting a different brand. All of the tires I looked at were all within about .2” off the diameter that I chose. Which brand tire are you looking at?

[@jasonyang2869]

@@DustinFaddis I was actually looking at the Toyo open country at. The overall diameter is 33.1. I think you are right. It's actually not that big of difference. I think I can accept that it might rub a little bit on the first few thousand mile.

[@DustinFaddis]

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

[@210078]

I just bought the exact same size tire for my 2019 ZR2...going slightly mad researching this!! I haven't had the tires installed yet..Talked to people at 4 wheel parts, told me the ZR2 already has the leveling system etc... will these fit without the 1.25 leveling kit?! My goal is to get the 4" BDS suspension lift installed, (down the road) and the folks at BDS don't recommend NOT doing the leveling kit in unison with their suspension. Will I be able to get away with just grocery getting without a leveling kit for now?! Your thoughts would be greatly appreciated!

[@thesal1000]

Did you have any clearance problems with a taller tire in the stock, spare tire location?

[@DustinFaddis]

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

[@Brzsteve86]

Wonder if this is the same with a z71 doubt it tho since the zr2 has extended fenders

[@DustinFaddis]

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

[@Kovaction]

What did you use to calibrate the speedometer? I have the Hypertech from my 2016 but I was told it won't work on the 2021...

Question? Are the mudflaps by WeatherTech? Interested in them. No the best looking, but like you said....they wont win any beauty contest, but they get the job done. Thanks man. Also again, thanks for the informative content.

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.

[@justkillintime7554]

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

[@DustinFaddis]

@@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.

[@harolddenton6031]

On my new 2024 zr2 it came with 285/70R17 goodywar terriroty m/t tires. I am thinking about going with 295/70R17 or 305/70R17 new tires by either toyo,yokohoma or cooper. But those skinnies 255 width pizza cutter skinnies tires make more sense for better fuel economy.

[@janpayne964]

Maybe it’s in the comments and I didn’t see it. Do you think putting the 1” lift in the back and 2” in front. That the rear would gain a bit more clearance? Thank you for the great video.

I have the same truck, What leveling kit did you use or suggest. I only want an inch or two.

[@DustinFaddis]

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

[@MrRyanmcmahon]

@@DustinFaddis great thank you very much.

[@MrRyanmcmahon]

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.

[@DustinFaddis]

@@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

[@azpathfinder6191]

Do you think those tires would fit on a GMC Canyon? I plan on throwing a 3 inch lift on it.

[@DustinFaddis]

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

[@erickwells2493]

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.
