correct tire pressure

You can go to the Goodyear web site and see their tire loading inflation chart, recommended tire pressure vs weight on the tire. But as noted, you need to weigh each axle, and preferably each tire, to see just what the correct pressure should be. Max pressure will ride harder. And will cause more wear in the center of the tread if it is too much pressure for the weight. But is a safe bet without knowing weight.
