I have a JKU with 3.5" lift and 35/12.50/17 MTR Kevlars with a superchip. Be running it for 65,000 miles with 3.73 and live in hilly Georgia and jeep dies great. I can run 80mph on hwy with no problem.

 

Jeep rides great. Typing on s damn cell phone.

 

I just put mine on yesterday. I was running 16"steel wheels and 32's and went to a 15" inch alloy and 35 KM2's. I think the acceleration and performance on flat roads is about the same. I am running a Superchip on 93 tune. I haven't programed the tire size change into the computer yet so my speedometer is still off.

 

auto tranny + 4.10 gears + 35" KM2's + Colorado hills/mountains = shitty ride

Regearing very soon along with RIPP Supercharger (once available)

 

I have a 6 speed , 35" km2 and 3:73 gears. Been driving with the 35's for a month and it sucks. Forget about 6 th gear all together and plan on downshifting to 4th on the freeway if there is any incline. Around the city is fine and if it isreally flat where you live you should be ok for a while. I off road pretty hard with the stock gears too. Just use 4 wheel low. By the way my jeep is in the shop right now getting 4:88's and arb's Can't wait to get her back tomorrow.

 

Have to agree, as long as you can live with it. Go slow it's a jeep.

 

BTW, I have an auto and gas isn't a concern for me. I don't care if I get 12 mpg. I'm just worried about performance (ie if I need to pass up someone doing 40 mph in a 55)

 

35/12.50/17 km2 auto 3.73. I'm fine with them.

 

Ive got 35's and i HAD 3.73 but now ive got 4.88 with a manual and what a difference. No regret one bit.

 

ran that setup for 2 years with an auto, wasnt bad because most of my driving is city but I still hated it lol. got 5.13s now and its a lot better. dont fear the gear!!
