Karl, recommend having matching wheels on the same axle ... if not on both axles. It appears the previous owner either: 1) did things on the cheap, or 2) lacked attention to detail.

My son bought a 1997 BMW M3 that had 3 wheels the same size, while 1 rear wheel was the larger staggered size wheel. It cost him hundreds of dollars to buy another larger size rear wheel.
