Power change running 30 x 9.5 tires
i currently have 32 x 11.5, 15 tires on my 2" lifted CJ7 (with stock gearing, T5 ) and need to replace the tires soon.
running the 32's are really sluggish on hills on the highway and would like to replace them with something smaller which would give me more uphill/passing power. my 5th gear is pretty much useless (can't really accelerate on it with any kind of incline or headwind) and running in 4th up a slight hill on the highway is a chore if there are more than 2 people in the truck.
was wondering if anyone notices a significant difference going to 31 x 10.5? or should i just go all the way and get 30 x 9.5?
i don't really go hard core offroad (mostly just fireroads getting to trail heads for backpacking) so big tires don't mean much to me. i mostly drive on highway, etc. and just don't want to get laughed at by my friends when they see a 18 wheeler pass me.
