What Air Pressure Should My Trailer Tires Be Run At

Question:

If I put the max air pressure to 65psi stayed on the side wall and drive the pressure will increase as time on the road increases, at what psi should I be worried about a blowout? Should put my tires to 58 or so and let them increase to 65 and release air if psi is getting higher than the 65

You always want to inflate your tires like the # AM1ST96 to the maximum air pressure when the tires are cold; the tires are designed to handle the additional air pressure that will build up as the tires get hotter. For every 10 degrees in temperature the tires increase, the PSI increases about 1 psi, but again, they're designed to handle the increase in pressure as your tires warm up. If your tires say 65psi, you'll want to start each day at 65psi; lower pressure can cause uneven wear and is just as bad as tires overheating when it comes to causing malfunctions.

If you're concerned with the tires overheating you might want to get a TST TPMS for RVs - Color Display - Signal Booster - 4 Tire Sensors # TST-507-RV-4-C which monitors air pressure and temperature of your trailer tires. This kit comes with 4 sensors and an easy to read color LCD monitor that will alert you when tire temps get too high, so that will give you some peace of mind while on the road that your tires are running in the safe zone.

I've linked a brief review video of this system for you to have a look at.
