right i know they will fit the tire fine what im worried about is rubbing on my leaf springs and lower control arms. i read this earlier is this true or no? thansk for the help

No matter what width rim you are running. You want one with 4" or 3.75" back spacing. Any more than 4 and your tires will rub your leaf springs and Lower Control Arms. This is also based on a 11.50 to 12.50 wide tire. If your tires are wider then you'll want even less back spacing.

well how big are you planing on going
if you are ruining stock rims now
and plan on running the same tire on the new rimes they will fit fine
if you plan on something different you should post your plans
so you can get the best response

I was running 33s on a 15x8 rim with 4.5 backspacing and had no issues with the leaf springs. I did rub the LCAs when the steering wheel was fully turned. You should have no issues at all with that tire and rim set up.
