Load Range F Trailer Tires (12-Ply and 16-Ply)

Load range F sits between E and G. On 16-inch trailer tires it is the 12-ply rated class, about 3,960 lbs per tire for an ST235/80R16 at 95 psi. On 17.5-inch commercial sizes the F rating is a 16-ply tire built for 125 psi. This page lists every load range F tire we stock, loose and mounted on a wheel.

The wheel has to be rated for the tire's pressure. Standard 16-inch steel trailer wheels are often rated to 80 psi only, so check the stamp on the back before mounting a 12-ply tire. The assemblies on this page are matched to wheels rated for them.

Common questions

Who needs load range F?
Gooseneck and equipment trailers running 12K axles on 16-inch wheels, and anyone moving to 17.5-inch wheels on 10K to 12K axles.

Can I mix F with E on the same trailer?
Keep all tires on an axle the same size and load range. Mixing across axles is possible but the trailer is only as strong as its lowest-rated tire.

What pressure?
95 psi for the 16-inch 12-ply, up to 125 psi for the 17.5-inch 16-ply. Run what the sidewall shows for your load.
