I had the factory all black Chevy wheels on mine , on my 2020 Rally RST and then i put on the trail boss lift and put on 285/50/22 Nitto Ridge Grapplers , plenty of room.

I have the same truck only in black and got rid of my Bridgestone Alenza tires right away, too much of a car tire, so I had the dealer install the trail boss lift and I went with Nitto Ridge Grappler tires 285/50/22, I tried 285/55/22 tires but they were very close to touching at full crank I think with a .236 wheel spacer they would be fine, so far the tires have been good they look aggresive but are pretty quiet, I must say they are not the greatest on snow or on wet pavement you can break them loose easy with the 6.2 , but overall I like them and the look.

Sharp truck!! I too have the same rims but on a Silverado, what is the tire size on the sidewall and what kind of tires ? are they Nitto`s and is there any wheel spacers?

No that is the trail boss lift but it does come with longer axles, and with them installing it it doesnt void your warranty, I had it put on my 2020 RST Rally with the 6.2 and put on 285/50/22 tires

Thanks, looks amazing!

What size lift and tire size did you go with? Looks great !

I have 285/50/22 on my 2020 RST with a trail boss lift and factory black 22 inch wheels, I iwent to discount tire and they test fit the 285/55/22 and they fit but was super close on the inside, if I had a .250 wheel spacer I think they would be fine. As far as how good they are, they are not great on snow but any large tire isnt and wet roads they break loose very easily, and the noise is not bad at all, I have 17000 mile on mine and they just make a little noise but you cant have a big aggressive tire and not have any noise , but you cant beat the look. The ride is pretty good also, I would buy them again.

Nice truck , but the rims just arent my style.

Do you have oversizes tires? or rims that stick out? do you drive on a gravel road fast? do you have running boards? All these things factor in.

I have a 2020 RST Rally 6.2 which has the 22 inch factory wheels and had the dealer install the factory trail boss lift and I put on 285/50/22 Nitto Ridge grapplers and there is NO rubbing at all in fact I tested the 285/55/22 Tires and they were just about touching but but little to no extra clearance but still fit.

I dont blame you those factory GMC wheels are very ugly

Looks good but I think 35 inch tires would be perfect without lifting it more, 6 inch lifts are too high in my opinion

Yes, your current 20 inch tires are 1 inch taller than the 18`s

Looks good!! maybe get the front windows tinted and add a stubby antenna

Well I dont know about the GMC but that is only 32.58 tall tire , I have a Silverado RST and I put on TB lift and I put on 285/50/22 Nitto Ridge Grapplers which are 33.22 tall have have no rub at all.

What lift did you go with? and tire size? I have the basically the same truck only the RST Rally with the 6.2 and I put the TB lift and went with 285/50/22 Nitto ridge Grapplers

I went with the Nitto Ridge Grapplers , aggressive side wall and nice and quiet.

I do believe it does void the warranty if not done by GM service , but how does it sound ??

I was also looking at both, going back and forth and ended up getting a Black RST with the 6.2 and 10 speed transmission, I just didnt like the huge front end of the GMC but the 10 speed is awesome.

Nice thank you!!

what kind of bike rack is that ?

I swapped out my Bridgestone Aleza`s for some 285/50/22 Nitto Ridge Grapplers much better tire.

The tire size is one inch larger on the 21
