Does anyone know if there is a dealer that only sells Michelin tires? The reason that I am asking is because I was wondering if they might carry the Pilot XGTZ4 in the following tire size 255/40ZR17. I have seen 255/45ZR17 in the tire rack but not 255/40ZR17. If I do decide to buy a 540i Sport (sedan) I would like to retrofit style 19 wheels in place of the OE wheel (style 32). The OE wheels are mixed width (17 X 8 front and spare; 17 X 9 rear). Style 19 is available in this width. The tire size is 235/45ZR17 for the front and spare and 255/40ZR17 for the rear. The auto pros say if you are going to put on an accessory or aftermarket wheel on that is the same size as the OE wheel. Same goes for tires. I don't really care for the OE Dunlop Sport 2000's. Michelin tires are the best on the planet. The Pilot XGTZ4 is an ultra-high performance all-season tires instead of a summer tire and is the tires I would like to use when retrfofitting style 19 wheels. Any info about this would be very helpful.
