my jeep is a stock suspension 89 2door 4x4 4.0. but it hase 30-9.50 tires on stock rims. they bub on the lca's what is the best way to cure this? what i meen is just lifting it gonna work? or am i gonna need to go less backspacing? cause im worried if i go less backspacing its just gonna rub the fenders? am i gonna have to do both?

 

Sounds like BS is in your future. You can also find great write-ups on trimming the fenders. I just did mine yesterday and have 15x8 w/ 4in. BS. No rubbing at all.

 

yeah, you're gonna need to get rims with less backspacing.
stock rims are usually 15x7 with 5.25 inch backspacing. for those tires, ideally you want an 8 inch rim with 4 inch backspacing. that should get you away from those control arms. but may get you closer to the edges of the fender and or flares. you may have to go up an inch or two, or minimal fender trimming.
those rims will handle 31x10.5 quite easily and can possibly work with 33x12.5 with the appropriate fender trimming.
other option is 3.75 backspacing. they won't stick out too much with 9.5 tires.

 

I had the same problem on my 33x15x13.50 swamppers i just swapped rims and all was good. mine was rubbing on the rear leaf springs didnt notice till i had to replace a pin in my 588 gears

 

The backspacing will fix it. I was running 31/ 10.50's on stock wheels. It rubbed the control arm and sway bar. I found a cheap set of steel wheels with around a 4" backspacing and it still rubbed when I backed up with full turn. The only reason was for that was because I had messed with my flares so the inside was sticking out a little.

Im thinking that with the 30. 9.50's you would be fine just getting new wheels.
I went with something like this.

ok looks like new rims is the way to go then.

 

if you like the craiger soft 8's you can get them for about $40 a rim. thats what i got mine for (in 2007 from discount tire).

they are 15x8 with 4" back spacing. i still use them today with my 33 TSL super swampers.

When you get the new shoes post pictures=]

 

When I bought my 31x10.50 on stock wheels, I replaced the OE steering stop bolts with slightly longer bolts with lock nuts and adjusted them so that the tires don't rub against the lower control arms. Cost me a few bucks at Lowe's. Some owners don't replace the stop bolts but just use washers to adjust the stops out.

 

yeah soft 8's is what i was planning. they look good and there dirt cheap.
