Pontiac dealer also says I should rotate the right front to left front and right to left with the rears, also. He said some Cadillac models have the same arrangement and several customers have had good luck with this method.

I rotated them today and carefully examined the tires for cupping, etc. I could see no evidence of abnormal wear hence no reason I can see to have alignment checked. It gave me a chance to clean the inside of the rims, which are very visible on these forged aluminum wheels. You don't realize how huge these tires are until you take them off the car.
