What is the PSI Rating for a 205/65-10 Trailer Tire

Published 08/02/2016

Question:

I recently acquired a small boat and trailer trailer see picture attached and tires, ref: 205/65 - 10. An additional marking on these types is20 5x8 0. Also, DOT K2BU Regrettably, I do not know the weight of the boat or trailer but the boat is a 12 foot semi rigid Caribe. The prior owner suggested when asked that the tires should be inflated to 32. Could you kindly give me some advice as to correct tyre pressures. Much appreciated.

The 205/65-10 trailer tire size comes in different load ranges and each load range has a different psi requirement. A load range B in this size should be inflated to 35 psi. Load range C inflate to 50 psi. For load range D inflate to 70 psi. And for load range E inflate to 90 psi.

The psi rating is usually on the tire somewhere. I believe the maximum that the 12 foot inflatable Caribe can weigh is around 1,600 pounds not counting the trailer (empty it would weigh much less, especially if the motor was removed) so any of the load ranges in a 205/65-10 will have the proper capacity it is just a matter of filling them to the proper psi.

Are there any other markings on the tire; front or back? Anything you can find might help.
