cts 06 3.8L 18" WHEEL SPORT WINTER TIRES/WHEELS
 

Any one found P225/50R 18 snow tires and 18" x 7.5" wheels that will fit the WHEEL SPORT APPEARANCE package? Tire rack says their wheels won't fit because of oversize performance brakes on CTS with this package. Also they only have P225/45R 18 tires. Finally any one have info on aftermarket tire pressure monoriting system (TPMS) tire stems? They are $61 @ from GM.
Discount tire does not have P225/50R 18 tires either.
