need help with tire rub...

i just bought some bfg tires and cragar rims. they stick out the sides a bit and when i hit bumps in the road or dips they rub. i need some advice on what to do. i think rolling the fender lip might help but i dont think it will stop the problem because it would still hit there. i did my share of searching on this topic and couldnt find much. the rear rims are 15x8 bs 3.5 i think and the tires are bfg radial t/a P275/60R15.

Re: need help with tire rub...

Do both sides stick out the same? Or just that 1 side? Is your car lowered any?

I had 285/17s on 5" bs wheels on (at stock height) and never rubbed once. But if the rear end is off to one side, you might need a new PHB, maybe just new bushings in the one you have.

Re: need help with tire rub...

the problem is the backspacing, you need at least 4.5" of bs in a 8" rim for it to fit properly on a 3rd gen.

You can roll the fenders, but that wont solve your problems.

Or you can swap in stronger rear springs, raising the rear a little and keep the car from hitting the tire. Moog Iroc replacements would probably do the trick.

Re: need help with tire rub...

I had the same proem on my 84 Z28 with drag radials. Try the wheel spacers, they gave me that extra 1/4 inch that i needed

Re: need help with tire rub...

does anyone think dragbags or coil spacers/ shims will help any.. i really dont want to buy new rims.. i know i should have gone with more backspacing but its too late for that now unless some one wants to buy the rims for 150 a piece.. they have like 5 miles on them haha

Re: need help with tire rub...

they wouold both help, the drag bags would be better, but they are both still bandaids. New IROC springs for the rear are not that expensive and will most likely solve this issue

they usually make the rear sit at least an inch higher
