Proper Inflation and Inspection – Before every towing trip I quickly check the PSI of each tire and inspect them for damage. The sticker on the trailer recommends 65 PSI cold tire pressure meaning measured the morning before travel.
What should the tire pressure be on a single axle trailer?
A single-axle boat trailer with a 2,490-pound GVWR (trailer plus cargo) rolls on ST175/80R13C tires with a max trailer tire PSI of 50 pounds. At 50 psi, each tire is rated to carry 1,360 pounds, or a combined 2,720 pounds for the pair of tires.
Is 80 PSI normal for tires?
The 80 psi is required if the tire is operating at rated load. You most likely have a load range E tire. I have run load range E tires for years on my 4 Runners at 32 psi front and 30 psi rear.
What is the tire pressure for RV tires?
The tire pressure on an average 16″ RV tire can be anything between 35-80 PSI or 280-550 kPa. That’s a wide range – and you need to find the right number for your specific weight and number of wheels.

The trailer tires need to be inflated enough to handle the top load from the trailer, their sidewalls are designed so. But, with less than specified psi, the tire sidewalls will start generating excessive heat and result in failure.
Should I inflate motorhome tires to max psi?
When you weigh the RV it should be fully loaded including food, clothing, full fresh water tank, passengers, towed vehicle, etc. Once you have determined the heaviest end of each axle you need to inflate all the tires on that axle to the recommended PSI.
What should the tire pressure be on a 5 th trailer?
Trailer tire pressures correspond with the load rating. Trailer tires identify the load range using a letter system. Most travel trailer and 5 th wheels tires fall between range B and E. As you move up in load range the carrying capacity of the tire increases as does the maximum inflation pressure.
When to inflate trailer tires to Max psi?
Trailer tires should be inflated when they are cold and should be inflated to the max psi rating on the sidewall. In your case you would want to run 80 psi. If you don’t inflate them to the max psi figure you will lose weight capacity and potentially cause the tires to overheat and fail. helpful expert reply by: Jameson C

RV trailer owners having tires with greater than 85 PSI max rating can use the manufacturer’s tire load charts available below plus add a 25% margin. For trailers with max cold air pressure greater than 85 PSI, until the trailer has been weighed, never inflate less than the manufacturer label or the max cold air pressure molded on the tire.
