We purchased our 2003 S60 with Pirelli 235/45 R17s -- low profile tires with the alum. hubs. They look good, but we've had nothing but problems, especially when the weather turns cold -- they just go flat. Service center says the hubs contract in the cold and the seal breaks. (This doesn't sit well with me, but whatever...) Anyway, we're now looking at purchasing new tires and was told by the Volvo dealer that we can't replace the current set with more of a touring tire (higher profile) because the "car's ABS was programmed for the 235/45 R17s and if you put a different size tire on the ABS won't work properly." I can see how this might be an issue, but need some outside validation. Is this true? If so, can the car's ABS be re-programmed? Thanks in advance.
