Rear Tire Pressure Survey

[darrell]

I carry the Cycle Pump and their air branded air gauge I attach in line when adding air. I have checked all my gauges against another persons calibrated gauge so know the adjustment factor for each one. My 3 gauges have a range of 2.5 psi difference between them. When traveling I check tire pressures every 2 - 3 days adjusting if a ½ # psi off my 38 and 42 setting. If significant elevation or temperature change from day to day I check daily. The reading from the bike is strictly to verify I’m not leaking air and a close to 4# difference remains front to rear otherwise useless to me. Pressures are always checked when tires are cold.
