Tires

Hey guys!
I'm planning on gettin' some 31 or 32" tires.
I'm running on a 3" lift with 235/75 15" on stock rims.

Can I run with 32" with the stock rims?
Is it mandatory to re gear?

I think you may run into some rub issues at lock due to wheel off set (not 100% sure. Somone please verify) As for gearing I had 3.73s and flat land wasn't bad. Will not win a drag race but cruising at highway wasn't bad as it kept the rpms low. But any weight or uphill or acceleration will KILL your mileage. I was averaging 14-mid 15mpg in the highway due to Texas and their love of bridges. Made the call to go to 4.10s and i don't regret it. Got all the acceleration back that I had and my highway mps are now mid16s.

If you have the 3.50 gear set you will likely hate life.

Follow the build!

Yes on the wheels, but you will need to adjust the steering stops. And that will increase your turning radius.

4.0 or 5.2? You can run 32s on factory wheels. I ran 33x12.50 for a while.

Okey dokey. Yeah, it's the 4.0
I'm not sure about the gear it has, guess it's stock.
So the concerns would be the turning radius, gas mileage, and the uphill thingy. Guess I'll go for a set of 31s
Right now it has 235/75 but I feel like some bigger a/t ones

Most 4.0s came with 3.55. 3.73 was optional.

With 3.55 and 32s the ratio = 3.21
With 3.73 and 32s the ratio = 3.38

Thanks man.
It has a 3in lift. With 31s I don't think I'd have to replace my shocks or anything right?

I would assume with the 3in. lift, they changed the shocks then. Adding tires does not warrant changing shock absorbers.

Are you still planning running the stock rims? You might be better served with a wheel with less offset or a set of 1" wheel-spacers.

Yeah they'd have to have gotten longer shocks.

Damn, those things are probably begging for mercy. Get some longer shocks and enjoy a much better ride.

Holy crap.. get those shocks replaced with longer ones ASAP. Stock shocks have only about 8" of travel, they sit about halfway in at ride height, and the shock length is designed for a stock height vehicle. With 3" lift and stock shocks, you're looking at having only about 1" of downtravel* left on the shocks. Not good for ride quality, handling, or shock life.

* downtravel = amount of extention available on the shock
