GM Tire Performance Criteria (TPC) "Survey"
I would appreciate very much if those who have OE tires would post the specifics of your vehicle along with the TPC number found on the tire. It may have a couple of letters behind the number such as MS to indicate all-season.
Reply in this manner.
09 Malibu LT2 I4 AT6 (OE tire size) (TPC number) (make & model of tire) ( did you pay extra for wheels, ie price listed separately on sticker such as maybe a chrome upgrade. Simply answer, yes or no.) (same for tires. Answer yes or no.)
When sufficient data starts coming in, I'll analyze and post back.
