The wheels that have "crossed over" from 1st to 2nd generation have new casts and part numbers. In
looking at RealOEM the 1st generation R97 (pn 36-11-6-768-980) is noted as "ENDED". Does this mean that replacing a damaged 1st generation R97 means getting a set of 4 2nd generation R97s (pn 36-11-6-775-685) to maintain run flat tire compatibility?
