Everything 13 inch for a trailer on one page: ST175/80R13 tires in radial and bias, 13x4.5 wheels with the 5 on 4.5 bolt pattern in galvanized, white spoke, black and silver modular, and the same tires already mounted, balanced and inflated on those wheels. 13-inch is the standard on jet ski and personal watercraft trailers, small aluminum boat trailers, pop-up campers and light utility trailers.

Common questions

Which 13-inch wheel fits my trailer?
Nearly every 13-inch trailer hub is 5 on 4.5. Count five lugs and measure center to center across two studs, skipping one; 4.5 inches confirms it. Galvanized is the saltwater pick, white spoke is the classic, modular is the clean look.

Tire only or mounted?
If your current wheel is sound, buy the tire. If the wheel is rusted, bent or you want a ready spare, the mounted assembly costs little more than the two parts and arrives ready to bolt on.

Can I move up to 14 inch?
Sometimes, with fender clearance and the same bolt pattern. A 14-inch 205/75R14 is about two inches taller. See our 14 inch trailer tires and wheels.
