Trailer owners, this 2-pack of complete tire and wheel assemblies makes replacement or upgrades super easy! Each set includes a 4.80-12 tire mounted on a 12-inch diameter by 4-inch wide rim with a 4 lug on 4-inch bolt pattern. The load range C rating with 6-ply construction means these can handle up to 990 pounds per tire at 90 PSI maximum inflation - plenty of capacity for most utility trailers. The tread depth measures 5mm with an M speed rating, and the overall diameter is 20.7 inches with a section width of 4.8 inches. The center bore is 2.95 inches, so they'll fit most standard trailer axles. Whether you're using them for travel trailers, camper trailers, landscape equipment, cargo haulers, boat trailers, horse trailers, or farm equipment, these are versatile enough for pretty much any utility need. The best part? They come fully assembled and ready to bolt on - no need to mess with mounting tires yourself or paying extra at a shop. If you're tired of dealing with flat tires or worn-out trailer wheels, having a spare set like this on hand can save your trip or workday when tire trouble strikes.
