Appropriate tire weight gives your bicycle a chance to roll rapidly, ride easily, and fight off pads. Limited tires need more gaseous tension than wide ones: Street tires normally expect 80 to 130 psi (pounds per square inch); Mountain tires, 30 to 50 psi; and hybrid tires, 50 to 70 psi. To locate your optimal weight, begin amidst these extents, then factor in your body weight. The more you gauge, the higher your weight should be. For example, if a 165-pound rider utilizes 100 psi on his street bicycle, a 200-pound rider should run more like 120 psi, and a 130-pound rider could pull off 80 psi.
