I've got 37s and 4.10s...... Plenty of power..... My gas mileage is around 17.5 right now in the city, and on the highway I get about 20.

Everyone I know that gets 35s ends up wanting or getting 37s. Just get the 37s and save yourself lots of money. Trust me, you'll want the 37s.

 

How are 35s and 37s for highway driving? I drive around 12-15 miles highway a day, plus I'm thinking about the long trips we take on the highways. I have an auto and was thinking 4.88 for 35s and 5.13s for 37s, will the engine be over revving?

 

It won't be with an automatic and it's .69 OD. I've got 35's and 5.13's and if I was doing it over I'd go 5.38 and 37......in a heartbeat.

 

37's for sure here are a couple pics of my JK with 35's and 37's. I got 12-16 with 35's and 11-15 with the 37's.
35's

37's





Now I have 38.5's

 

How do you like those Truxus tires. I was out with a guy with them on a 62 or 63 Willys and was impressed with how they performed. How are they on the road; are they noisy. How where they to balance?

 

I'm running 35's, auto w/ 5:13 gears (replaced stock 4:10's) The gear up has my engine turning 300 rpm more at 60mph, so I fell like I have a little more "get up and go" than I did with factory set up. As far as mpg goes, I was getting 18mpg factory. I now SUCK GAS(13-14mpg) if I get on interstate at speeds above 70mph. If I go on a trip and use non-interstate routes, and keep rpms under 2000, I still get around 18mpg. Still gets good in town too. But............. wish I had 37's!!!!!!!!

 

they didnt balance out for sh!t, I put the 37's back on.

 

The guy is was out with really liked his; but then I found out that he trailered his to trails. The most road time he got was running a few miles to his motel or campsite so balance must not have been an issue for him.

I had heard they didn't balance worth beans.

Thanks

 

I am concerned with 37's of creating a higher center of gravity. Does 2-4 more inches make that big of a deal?

 

37's on a stock width CJ or TJ are one thing. But the JK is wider and more tolerant of a higher COG. As to whether it's a big deal it depends your vehicle, on where you are, and what you do. For instance I think 37's are far more desirable and needed on a 4 dr than 2 dr. In the rocks of western Colorado and Utah they are more needed than in flatland areas.
