Doesnt sound like much would change in my case then. Going to 18's with 35's may even add some sidewall for me.My Sahara Altitude shipped with 32s on 18s, and I picked up some Rubicon take-off 33s on 17s. I immediately noticed a softer ride, which is quite nice.
It's basic math - a 32" tire on an 18" rim has ~7 inches of sidewall. A 33" tire on a 17" rim has ~8 inches of sidewall. That extra inch makes a big difference in the softness of the ride.
The additional rash could be a problem. Or, I could look at that as characterThey ugly don’t do it, everyone wants more meat !!! Haha if that’s your style go for it, but a buddy of mine did that at a local shop they talked him into 18’s and it doesn’t quite look right, he hates it Ofcourse, that extra inch really likes to get rock rash
