BMW only uses the PSS for 20s for now. Just bought a set of PSS for my e90 and wanted to price compare from the dealer, they don't have PSS for our 18s or 19s. Very unfortunate. They're a major upgrade from those conti sport contact 3s that came on my car. Can't chirp the tires shifting into 3rd anymore
