Trailer Master Multi Duty APT-1 245/70R19.5 135/133M H 16 Ply tire

Commercial Highway Trailer Tire

The Trailer Master Multi Duty APT-1 is a highway terrain, all-season tire built for commercial trailer axle positions. Its ribbed tread pattern maintains continuous road contact to improve steering responsiveness and towing stability. The strengthened internal structure and durable compound resist deformation under heavy loads. This 245/70R19.5 tire carries a 16-ply rating and Load Range H for demanding commercial use.

Suits Heavy-Duty Trailer Axles

This tire fits medium and heavy trucks needing a 19.5-inch rim diameter and a 135/133 load index for dual or single fitment. The M speed rating supports operation up to 81 mph on highways. Buyers requiring a different rim diameter, a higher speed rating, or a passenger-car load range should look elsewhere. The overall diameter measures 33 inches and the section width is 245 millimetres.

19.5-Inch Rim Diameter Decides Fitment

The 19.5-inch wheel diameter is the single specification that determines whether this tire matches the vehicle. Verify the wheel size stamped on the existing rim before ordering. An incorrect diameter makes the tire unusable regardless of load rating or tread design. The tire is sold individually; rims are not included.
