Trailer Tire & Wheel Assemblies

Match the assembly to your trailer's tire size, load range (ply rating), wheel bolt pattern (PCD), hub bore diameter, and weight rating; check your trailer tongue plate or owner's manual for the required tire size and load capacity before buying

Choose a tire with a load range and rated capacity that meet or exceed the maximum axle or gross vehicle weight rating (GVWR) divided by the number of tires per axle; when in doubt, pick the higher load range for heat resistance and longevity

Pre-mounted assemblies save time and ensure proper seating and balancing for most buyers, while separate purchases allow mixing specific wheels or tires for specialty needs; pre-mounted is convenient for immediate replacement

You must match the wheel's bolt pattern (e.g., 5 on 4.5"), center bore, and stud diameter to your trailer hub and studs; measure existing wheel or hub specifications or consult the trailer's documentation to ensure compatibility

Maintain proper tire pressure, inspect for cracking or uneven wear, repack wheel bearings and replace seals per manufacturer intervals, balance or rotate as needed, and store the trailer out of UV exposure when not in use

Use tires marked for trailer use (ST) when replacing trailer tires; passenger (P) or light truck (LT) tires may have different load and heat characteristics and can affect handling and compliance with vehicle weight ratings

Trailer tire and wheel assemblies commonly span a range from lower-cost options under $100 to higher-rated assemblies several hundred dollars each; higher-priced units often offer stronger wheels, higher load ranges, or better corrosion protection, but fit and rated capacity are the primary purchase criteria
