Thanks for the info. and the offer, however if I let the factory set go, it will be wheels & tires mounted.

I need to get more than 13,000-17,000 miles out of a set of tires. Maybe the SP9000 is not what I need. I really would prefer a more performance all-season, but in the 18" size I am very limited.
