I know this is the 3 series forum, but doesn't hurt to try.
I'm looking for a set of 19" RFTs and TPMS that will work for a 2009 BMW 750Li.
Tires don't have to be perfect, but tread depth has to be acceptable for BMW. I believe their requirement is 7/32.
Also, if you have access to a set of oem BMW 7 series wheels, EVEN BETTER!
