I was wondering if someone could enlighten me on the meaning of J or JJ. To give you an example, the Audi A6 16" wheels are 16 x 7J, while those on the Chrysler 300M are 16 x 7JJ, and the wheels on the Lexus GS300 are simply 16 x 7-1/2.<p>Thanks!<br>

I think it has something to do with the wheel offset, but not positive

...where the tire bead seats. I was reading about it somewhere (I think in my Z3 owner's manual). I'll try to research it a bit and post or email you.<p>CraigB

The BMW owner's manual states, "Code letter for flange type"; I'm not sure what that means. I was thinking of Asymetrical Hump, which means the tire stays on the rim much longer, after losing air pressure. Sorry!<p>CraigB
