The difference between a load range E and load range F tire of the same size, 235/85-16, is the weight capacity and pressure. The Karrier Radial Tire, Load Range E, # AM10295, has a capacity of 3,640 pounds at 95 psi.

The Load Range F Tire, # AM10501, has a capacity of 3,960 pounds at 95 psi.

Trailer tires should always be inflated to the maximum psi rating indicated on the tire. If a tire is under inflated, it will cause the side wall to build up more heat faster and cause the tire to fail. Trailer tires have a thicker side wall so that they can handle more vertical load, passenger vehicle tires do not have as thick of a side wall so they should not be used on trailers.

Have a 5th wheel trailer, at this time I have a ST235/85R16 load rated E can I upgrade to load rated F without having much of a size change? Thanks..

Switching to a Load Range F tire like the Kenda # AM10501 won't increase the actual size of the tire at all. You'll have the same size unit but with a higher load capacity (3,960 pounds) and maximum psi (110).

What would a load rating "F" mean on a 7 x 14.5 tire?

@JeffP that means it is 12 ply. I would look on the side of the tire for the max load/capacity since it varies from tire to tire within load ranges.
