without being able to drive the car it's hard to diagnose a problem of this sort. The 2 most common problems for trammeling of this sort are 1. bent wheels 2. having a pire this has a radial pull. which in essence is a defective tire. Bear in mind that many performnace tires will follow the grooves in a given road to some degree, but if it is really bad, it's most likely one of the 2 options above. If I were you, I would have a local shop take a look(and drive) and see whT they have to say. Aaron
