Just got a set of Michelin tires put on my Pontiac Grand Prix, 2001. Checking the recommended tire pressure on the label on the truck lid revealed that I need to inflate the tires to 30 PSI. This seems low to me, does anyone know why the recommended inflation is 30 instead of 35, which is where my other GM vehicles are set. The tire size is 225-60-16, my other cars have 15'' tires. Would this be the reason for the lower pressure? Thanks, Terry
