When I bought the car these wheels were on it and wanted to see if anyone can decode these imprints on the wheels since I know nothing about wheels.
They are BBS wheels and have the following marking:
F--81/2Jx18 H2
R--10Jx18 H2

I'm assuming the 18 is for 18" and on the rear the 10 is the width but I could be wrong. Not sure about the front at all.

Thanks in advance!

8 1/2 in the front 10 wide in the rear.

Great. Thanks bro! Is that the normal size folks go with on aftermarket 18's?

8.5 is pretty common in the front, either 9.5 or 10 in the rear is fine.. Lets see some pics of the wheels

Not a very good iphone pic but all I have right now. Will give you a general idea though.
