Max Tire Size - 20" Wheels 2011 Yukon

[Tusa123]

Afternoon all, I am wondering if anyone knows what the max tire size without rubbing would be on factory 20" wheels? Vehicle is a 2011 Yukon SLT.

Apologies if this is a repeat but I have searched and can’t seem to find the answer. Many people are increasing tire size but with a front end level lift or aftermarket wheels so those don’t apply.

My goal is to maintain the factory look with the 20" wheels but put a heavier duty tire. By jumping up to max tire size it will help fill the gap in the wheel well. Just trying to figure out what that magical size is.

Any help would be huge and pictures would be a bonus!

Thanks everyone!

There is not many options. The fenders in these trucks are taller than they are wider. The next size up is 285/55r20 that's about .43 inch taller. Next would be 275/60r20 which is 1.08 inches taller. I have put on this size with a level kit but still had some rubbing on a 2wd tahoe. May have to trim some plastic or cut some of the extra metal around the inside if the fender to get the extra room.

Donovan, thanks for the quick reply. Do you have any pics of your tires? Would be very helpful!

Huge thanks again, this gives me a starting point in terms of what to research. It sounds like the 285/55-20 is going to be my safest bet. Rubbing is a problem given my driving habits and on/off road balance which is a split between hwy, winter passes to the resort and spring/summer camping on old skid roads.

Cheers!

I had 305/50/20s with the tiniest of occasional rub.

Stock size but my wheels are 20x9.5

Sway bar. I'm looking to see if a simple wheel spacer will fix this problem. Dorman makes a ¼” 6 lug spacer that I think will work. There appears to be enough lug stud left on the oem studs to make this work. Keep an eye on the What Did You Do To Your Truck Today thread for an update. Since the item is special order from Kentucky it'll take a few days before I can post results and let everybody know if this works.

Back of the front inner liner for me.

I still think these wheel spacers will silver your problem. Our locations for rubbing are probably only different because of my leveling kit. Otherwise, I'm rubbing in the same general area. Sway bar on our trucks is behind the wheels instead of in front.
