I have a 2001 S with PSM. I can get a deal on a lightly used set of Toyo Proxes 888 where 2 are 225/40/ZR18, 2 are 255/35/ZR18. the 255s are shorter than the 265s I have today. I realized this is a small difference but I don't want to buy them and find out my PSM will trigger too much. Anyone know? (being rear tires, I am thinking PSM might apply the brakes to the rear more than necessary) THanks!
