Load Range C Trailer Tires (6-Ply)
Load range C is the 6-ply rated class of trailer tire, the right choice for jet ski and personal watercraft trailers, small aluminum boat trailers, single-axle utility trailers and pop-up campers. In the sizes here it carries roughly 1,360 lbs (13 inch) to 1,820 lbs (15 inch) per tire at 50 psi. This page lists every load range C tire we stock, loose and mounted on a wheel.
Ply rating is a strength class, not a count of actual plies; a modern radial marked 6-ply usually has two or three. What matters is the load figure molded into the sidewall. Match it or go up, never down.
Common questions
Is load range C enough for my trailer?
Add up the loaded weight of the trailer, including the boat, fuel and gear, and divide by the number of tires. If each tire sees less than about 1,300 lbs on a 13 inch, 1,700 on a 14 inch, or 1,800 on a 15 inch, C works. Close to those numbers, step up to load range D.
What pressure does it run?
Load range C trailer tires are rated at 50 psi. Run the full pressure printed on the sidewall when the trailer is loaded; underinflation is the leading cause of trailer tire failure.
Does 6-ply mean the same as load range C?
Yes. Load range C and 6-ply rated describe the same tire.
