Proper Air Pressure for Kenda Karrier S-Trail ST145/R12 Tire  


what is the recommended air pressure for a Karrier S-Trail ST145 R12 tire. Using the on a single PWC trailer. PWC is about 900 pounds. Your help is appreciated. Thank you


Expert Reply:

Unlike passenger car tires that have a certain range the tire needs to be inflated to, trailer tires should always be kept inflated to the maximum air pressure listed on the sidewall of the tire.

We offer the Kenda Karrier 145/80-12 (aka 145/R12) in a load range D or E. A load range D tire like # AM10130 has a capacity 1220 lbs when inflated to its max pressure of 65 psi. The load range E tire, part # AM10140 has a capacity of 1520 when correctly inflated to its max pressure of 80 psi.

I've linked you to our Trailer Tire FAQ article.
