Hey y'all I was wondering if any of you had 35's by 10.5's on their two door jeep. Also, i was wondering if you felt they caused your jeep to be much slower (acceleration wise).

I was thinking of getting some 33X12.5 but i thought the 35x10.5 might be similar to the ladder in terms of a decrease in acceleration.

tell me if my thinking is stupid

I am running the 35x12.50 and have the optional 3.73 gears and don't feel that it slowed me down at as far as getting up to speed goes. Can't pull 6th gear up hills or into headwinds though unless I am running way above speed limit. So I dirve it like a 5 speed unless I have a tail wind or am behind big rigs on the interstate, I stay at one truck length and some behind and that give me just enough air resistance relief to pull 6th at 70 mph.

that's also what I'm trying avoid also. I'd like to keep the use of 6'th gear. Would the decrease in weight/ friction from riding a 10.5" tire instead of a 12.5" tire be enough to keep use of 6th gear?

Most likely not.

There would be a little less drag, not sure if there would be enough less though.

i don't think it has as much to do with drag (from time width) as much as it's the overall increased circumference of the taller tire.

It's like playing around with the sproket sizes on a bike - going uphill on the small sproket vs the biggest one.

I agree with above post to a point. Circumfrence dictates gearing, however those 10.5's would weigh much less than the 12.5's so you would have much less rotating weight, which robs horsepower. I don't know if they make that tire in a radial though. Have you found them? What brand? I'm certain they would handle better on the pavement than the wider ones as long as the load range was up there.
