Hello everyone,
I put on 215 40 R17's on my Ronal rims on my 01 9-3 SE HOT. I should also add that the suspension was replaced with Eibach sport springs and lowered
30mm. The tyres have perhaps 20,00km and are showing signs of cupping on the inside. I rotate the rims every 8,000k and the car gets an alignment every year whether required or not. Everything is ship shape mechanically but I am perplexed about this. Any thoughts? I'm meeting the Bridgestone rep next week. I realize that these are performance tyres and boy are they ever noisy but they really stick. I don't drive quick (ie. burnouts, spin, etc.) but I do drive fast. I do feel that I should get at least 40,000k out of these don't you?Spyder
