Let me apologize up front if this topic has been addressed before but I couldn't find it in the forums. I am trying to decide on two different sizes of tire for my 2017 Ram 2500 Longhorn. The first is 295/60/20 (33.94" OD)which I am almost 100% certain will fit. The other is a 295/65/20 (35.12" OD). Both tires are the Toyo Open Country A/T II Xtreme. The truck is still stock and has not be lifted in any way or the wheels replaced. The tires will be going on stock wheels. Any thoughts?

35x12.5x17/18/20 will fit on a stock 2500/3500. May have minor rubbing on stock wheels. Anything with a +18 offset and you won't rub


2018 2500 6.4L

I ran 285/65 20s (34.6x11.2) without issue now leveled I'm running 295/65 and as stated you have slight rub at full lock with stock wheels.
