From more recent entries (GT5 & 6) we're missing BLITZ BRW, Covered Steel Wheels, Classic Wire Knock-Off, ENKEI ES-TARMAC, a whole line of made-for-game rims (GT-AaXX/GT-AbXX, XX being the number of spokes), HAYASHI RACING Street Wheel, PDI P525/525N/P814 (also made for game), Prodrive GC-010G, and probably some more that escape my mind right now.
