Can someone help me with the inside diameter of a 15” wheel for e36?


Recommended Posts

The only 15" 5x120 wheels I've been able to find are 7" wide so I'm thinking about going with steel nascar style steel wheels 9" or 10" wide.  I don't have a 15" BMW wheel to measure the inside diameter and wanted to double check before ordering.  I'm running stock brakes front and rear.

Hmm.  I see what you're saying.  I saw an e30 at Gingerman this year with steel wheels but didn't look close enough to see the set up.  


Bassett D-hole 15x10, 5" backspace, 1/4" spacer.  We run them with 245/40R15 Hankook RS4s.  The center mounting pad interferes with the brake caliper on E30 without a spacer, but probably clears on E36 given the larger rotor diameter.



or a smidge lighter:



Quick look says E36 also needs 5" backspace.  Use 5x4.75 bolt pattern - it's close enough to 5x120 for steelies and their terrible machining tolerances.  Add the spacer if needed to clear the caliper.
