Tire manufacturer recommended pressure not always right look in the drivers side door jamb as stated before. The reason is the tire maker does not account for vehicle weight and weight distribution. Just never go over max tire pressure on tire. Most of the time lower pressure is for better ride in that case you can get closer or at tire max pressure and get more mpg but sometimes pressure affects handling and wear. I had a link that told you how to find best tire pressure by checking it when cold then once warmed up after driving I think there was suppose to be 1 psi difference. But don't quot me on that.
