TRAILER KING RST
Trailer King RST tires: purpose-built rubber for the road behind your rig
Trailer King RST tires are made for one job: riding under a trailer. Whether you are hauling a utility trailer, a boat or a travel unit, this is trailer-service rubber designed to carry a load and track straight behind the tow vehicle. You can browse the model alongside the rest of the lineup on the Trailer King brand hub, and see every trailer option under all tires.
The sizes we carry
We stock the RST in rim diameters from 13 to 16 inches, covering small utility trailers up through heavier tandem-axle setups. These are the sizes we carry rather than the model's full size range:
- 13-inch: 175/80R13 at $80 and 185/80R13 at $86
- 14-inch: 205/75R14 at $98 and 215/75R14 at $109
- 15-inch: 225/75R15 at $126
- 16-inch: 235/80R16 and the taller 235/85R16
The two 16-inch fitments are the heavy end of the range — see the 235/80R16 at $155 and the 235/85R16 at $157.
Ratings we actually stock
Across the sizes we carry, the RST comes with an M speed rating and service descriptions of 91M, 94M, 102M, 105M, 117M, 124M and 128M. That load-index span — from 91 up to 128 — reflects the jump from the light 13-inch sizes to the load-carrying 16-inch fitments, so heavier trailers land on the higher-index sizes.
Price band and who it suits
Pricing runs from $80 to $157, which keeps the RST firmly in value territory for trailer owners who want dependable replacement rubber without overspending. It suits utility, boat and camper trailers alike. If you want a different balance, the sibling Ultra STR is a separate trailer model worth comparing, and the Ultra ST is another trailer option in the same family.
