Tire Sizing

[WildBill]

Im brand new here and to my Yukon. I need to put new wheels and tires on and I want to go bigger. Everywhere I read gives me conflicting info, so I need some expierence...

The plan is 305/55/20 Nitto trail grapplers and 20*9 -12 offset Black Rhino Wheels.

Right now the front stock keys are full up. I dont really want to lift much more (got kids), but I could do keys if I had to.

WILL IT FIT?

Thanks.

The nittos are about 33.2" in diameter. Depending on the agressiveness of the tread depth, you might get some rubbing. I know most people can get 33's with minor rubbing on aftermarket keys, so with stock keys, you might have more rubbing than most. If you wanted to play it safe, go with 0-3" aftermarket keys. That way, you shouldnt have a problem. There is a member in this section, s2kstephen that has put on 35s on keys and spacers, so your 33s should be ok. But I'd get some other opinions, but that's just what I've heard from this forum.

Good luck

U will rub a good bit with that set up. Go with a 305/50

So If I did the 33's, what kind of trimming am I looking at?

Would it fit for sure with a 2-3" Leveling kit?

i fit 33" discovery stts on 20 rockstars with stock keys cranked like halfway. no rubbing its alot easier then you think
