If I were you, I'd check with the tire mfg or a place like "TireRack". Never trust oil change places or a run of the mill tire shop. They are still living in the age of the 3K oil change/32PSI ideas. From what I've learned, the lower profile tires run/wear better at higher pressures. We have been running 38PSI in our cars for years. (Jetta TDI's, Hyundai Sonatas. Trucks, totally different ballgame (3/4Ton Dodge 4x4), 65 no load, 80 loaded.......Just my 2cents, OK, maybe a dime's worth.
