Tire size.

My 2021 bighorn came with 275/65r18’s. Curious to know if I can move to a 275/70r18 without any rubbing. Truck is stock with no lift/level. If so, what tires do yall recommend? Would like to go with something a bit more aggressive but not overboard.

Same question here. In my search it's difficult to find any conclusive answers. It would be great to have a "sticky thread" with confirmed maximums for various models and lifts. i.e. base, base+ORP, Rebel, TRX, base+lift, etc.

You should be fine. Alot of folks run 275/60r20's without a level, and these are pretty close.. They may rub a little so some trimming may be required.

Plenty of threads on this subject in the Tires subforum. Yes, you can run this size without rubbing. A General ATX is the only C range tire, all the rest will be E range, riding rougher and losing mpg.

I have 275/70 r18 Michelin Defender LTX M/S, stock ride height no rub. They are 33.2" x 11"
