hey guys i have a 2dr "x" with 4.10 gears. i will be getting new tires soon and was wondering if 35's are going to make my jeep a dog on the highway. i currently have 33's but just want a bigger tire. does anyone have this setup and if so hows the mileage, acceleration, and any breakage yet?

 

I've got 35's and 4.10's. It sucks!!! Bareable but it does SUCK!!! I get between 13 and 14.8 mpg. It does not like hills. Any hills. It likes 80 to 85 but struggles at 70 on the highway.

 

I have an unlimited X with an auto and 4.10's, and am currently running 35x12.50R17 BFG Mud KM's. It is a dog on the freeway, and has difficulty holding overdrive beyond 65MPH. It does fine in 3rd, but only gets about 13MPG. When you get it to hold overdrive it gets 19-21 with the 35's. These numbers are corrected to account for larger-tire-caused speedometer error.

Perhaps a less aggressive tread would help a little. Perhaps not.

14-15mpg You can get overdrive to work if you keep it over 75 on a uncorrected speedometer. But then your probably going 85-90 It's bearable, but I too am saving for gears.

 

OK so i should be fine with 4.10's on 35's considering i have a Manuel, is this mainly becuse i can physically put myself into overdrive?

 

I agree,I have the same set up with ProComp Xtreme A/T and its no better.
I dont understand how people could says it O.K. with Auto,4.10gears and
35's

 

4.10s and 35s=dog!

Its fine city driving but weak on the fwy.

 

I'm saving for mine right now. I know that as soon as I have my 35s I'll want higher different gears.

 

So what are the ideal gears for someone running 35" or 37" tires with a 6 speed manual in a JK? Right now I have 3.73's......what's that gonna do with 35 or 37's?

 

I have a 2dr manual with 4.10s and 35s. It's fine. Sure, 4.88s would be nice, but the 4.10s are OK for now. I actually get about the same MPG on the highway as I did with my 32s.
