Not 100% sure but I think with a front leveling kit you could clear some 33s.

The factory tires are 33's, for example with 20" rims the 275/60(%sidewall profile of tire width) it's a 33" tire with factory sra's.

You can go to a 65 series tire (for a 17" rim just the same, add 5 profile) which is roughly a 34 and still clear everything without any rub. Speedo's off just a few MPH.

Though with air suspension and in entry mode I'd expect some rub in the wheel Wells turning Max.

35"s do need a leveling kit but not a total lift.

Hope this helps if anyone is still questioning it!

I changed mine from 20's to 17's and put 295/70R17 but I also put Bilstien 5100 leveling shocks set at 2.1 that is the biggest tire I could put on without having to put a lift kit on it.

But you don't have factory rims so did your offset change and or rim width on the 17s? I have heard 285 series to fit but not 295 factory. Even with front leveling

Yes sir they fit. Of course I can barely fit my finger between the tire and upper control arm but it doesn't rub what so ever. My speedometer is only off by 1 mph. I checked it via radar. The rim width is 8
