Would like to know the rim width for a 89 Firebird, V6, 2.8L. The rims are original and the diameter is 15 in. Thanks,

my guess is 8

The 15"s would be 6" wide. The 16"s were the 8" wide ones.

wow 6 inches wide? is that even a rim

i though they are 15x7 not 15x6

It should say what size on the backside of the rim. I think about all rims do.

You may be correct. I've never owned a 15" 3rd gen.

The first IROCs were 15x7 & I thought (may be wrong) the "lower models" got 6" wide.

It's 15x7, no thirdgen had anything skinnier than that.

the 14" rims were 6" wide

Actually, the 82 3rd gens 14" wheels were 6"....So, 3rd gens have come with 6" wheels.

i had a hard time getting traction with a 255 cant imagine smaller

Thanks, i'll just do that.... hope to see a 7.

Guess I should have added 15" wheels not having 6" width.

Thanks, appreciate the help.

its 15x7 on all of the stock firebird rims i've seen, and thats 3 different kinds.
