Hi All,
After reading countless threads about appropriate tire and wheel sizes, I wanted to post to verify before I order my set.

I got the Jeep with Steering and Braking issues. Just replaced 4 tie bars and have ordered the HD Steering shaft and a new steering gear box.

Current tire rig needs to be replaced also, it is running 15x10 American Racing alum with 295/50-15 Cooper Cobra Radial GT tires. The rims barely fit on the stock hub and I get some rubbing when I do full turns.

I am looking to go back to 15x8s with this setup.
Cragar Soft 8 Black Steel Wheels - 15 in. x 8 in., 5 x 5.5 in. Bolt Circle, 4 in. Backspace,
BFGoodrich Mud-Terrain T/A KM2 Tires - 31X10.50R15LT

Does anyone run this setup currently? Would it be worth it to go for the KM3's around the same price? Could I run a 33?

This vehicle will be for mostly off-roading on my property with the occasional trip camping and to the beach.

Thanks All

What's a 'tie bar' ? :confused:
PLZ, fill out your vehicle info. ;)
What ring and pinon ratio are you run'n?
FWIW: I have run BFG A/T 33's on 15x8 Alcoa wheels for many yrs, and have no plans to change.

Tie Bar? Probably a place I could grab a drink. What I meant was 3 Tie Rod ends. Not sure what I was thinking.

I filled out what I could on the vehicle info. I would assume my ring and pinon ratio is whatever it was stock. All the mods were done before the owner I purchased it from.
 
Go to the rear differential cover. Look at the 3 O'clock spot, next to the cover.
There will be a letter stamped there on the flat part of the axle housing.
What letter is it? Is it a single letter or a double stamp?
There should be, on the front axle cover on the drivers side. A metal tag between the 2 mounting bolts. What does it say?

I have ran 31-10.5 on all my Jeeps. they will fit under a stock Jeep and have got me every where I have wanted to go.
 
I wanted to provide an update.

I ordered Cragar Soft 8, Steel, Black, 15 in. x 8 in., 5 x 5.5 in. Bolt Circle, 4 in. Backspace for $61.24 each from SummitRacing.
I ordered BFG KM3 31x10.5x15 from costco for $189 each.

Should have everything mounted and ready for photos within 3 weeks.

Thanks for everyone's help!
 
Sounds like a good setup can't wait to see the pics.
