Sorry, but I cannot agree with any the comments made. We see a lot of Porsche's, as well as other makes, whose alignments are way off kilter. Quite often, it starts with a customer complaining about the car handling funny, pulling, hunting at speed, or experiencing unusual tire wear; and every time we put the car on the alignment rack, it is a mile out of spec.

Cars with large diameter wheels, larger tires, and those driven over pothole infested roads simply go out of alignment faster than your average Prius. It is a simple fact of life. So if you want those 20" diameter low profile tires to live a happy life, expect you are going to have to invest in periodic alignment, or deal with the consequences. After all, it's your car and your money.
