proper tire pressure for bikcycles
The tire pressure range is printed on the side of the tire.
that depends on the size of tires U are using; Typically mountain bikes roll with fat tires, with recommended pressure ranges between 45 and 65 psi. Timothy :o)
pressures on tires are for max. You need enough air too keep the tire from pinching the rim when hitting bumps, rocks, logs. Max pressure means less give flex and cushioning from the tire pumped rock hard. Harder tires do work better on harder surfaces, rolling more freely. Softer tires give a bigger contact patch (flattening deflecting deforming) for soft sandy muddy snowy conditions; conforming to the soft surface. how much? I ride a 35 pound bike and weigh 165. I put my weight on the bike and look for proper inflation; some deflection but not enough to bother my bike mates saying they look flat. usually about 30 pounds or so.
