Hey Everyone,
So I Just purchased a set of 33x12.50r15 Cooper Discoverer SST Pros for my 1990 XJ. I currently have a Dana 30 HP out of an 99 XJ for the front axle with upgraded 760 Ujoints. Out back I have an 31 spline 8.8 out of a 99 explorer that I am about to put an Aussie Locker in. both have 3.55 ratio.(I know, ill get to changing them). My question is I am going to purchase a set of Crager soft 8 wheels and need help picking them out. I am thinking the 15x8 with 4.0 backspacing but my only question is that the tire says it is rated for 8.5"-11.5" wide wheels. Will this be a problem, or should I go to a 10" wide wheel? Also, I like the tires to poke out and so will I need to change the backspacing if I go to a 10" wheel? I do intend to offroad this vehicle a good bit. I have never purchased wheels before so please school me.

Thank you for your time!

 

15x 8’s work well with 12.50’s.
Just saw your in douglasville. I’m up in Forsyth.

 

That's what I am thinking. I know the go to for 33s is 12.50s with 15x8 crager soft 8s. I just wanted to make sure I wasn't doing something terrible. I don't want to go up to 10s as I know staying with an 8 is alot better for airing down.

Yeah, I am going to windrock august 29th-31st for the Warn event with BleepingJeep, you should. Come.

 

12.5s on 8" is the Gold standerd.

Chaulk your tires to tune your street air psi.

Id probly start at 25psi and chaulk would tell me to drop 5 psi..

Im running 35x12.5 on 8s with about 18psi currently. all tires air needs wants and desires are unigue find out what yours wants

never run the air the tire Shop puts in its bad Karma and the wrong psi

 

This is great info, thank you.
