I have them on my TJ. also lighter wheels will help, what kind of wheels are on there now?
This is true, 4 bangers have 4.10s

BadMojo11 Get some 32x11.5 tires if you want to go skinner. That's what I'd do. Also make sure you do a full tune up and make sure there are no other problems causing you to lose power.

What gearing do you have? Cause I have the 4cyl, 4.10 gearing, with 35x14.5(!!!!) and while it sometimes struggles to accelerate, yours sounds much worse. Which doesn't make much sense unless you have 3.07s and/or some power issues.

Gorbenshore Thanks for the info

LouieDelTorchio Going down to 31s might look a little funky at 4" of lift. To be honest, the biggest thing you can do is regear and thats about it.

From larger to smaller tires

I apologize in advance for any ignorance. I have a 4 cylinder, 2001 Jeep Wrangler 5 spd manual. It has about a 3in.-4in. lift and the tires specs are: 33 x 12.5 OR15L7 108 R M+S. My Jeep, currently, is very slow in acceleration. It seems to struggle at highway speeds and I don't push it past 60 mph. It is fine on residential roads but I think the bulky tires are slowing it down on the interstate/highway. I rarely take it off road (the previous owner did take it off road frequently), the treads are almost worn out, and I'm just looking for a good tire replacement that will get me better mpgs and something that will make my Jeep a little faster. I would like the same tire height, just skinnier, I guess. Also, would I have to buy new rims if I did get skinnier tires? I guess the rims would have to match specifications for new tires.I'm assuming that the axles will need to be re-geared as well. Any information would be really helpful. Thanks!
