Special Trailer Tire Load and Inflation Table
Tire load and inflation table for Special Trailer tire sizes with corresponding tire inflation pressures and load carrying capacities.
Trailer tires feature heavy-duty construction with a greater load range and tire inflation to be used on utility trailers. Maximum load capacity and maximum tire inflation depend on tire's load range and load index. Most trailer tires come with a load range of B, C, D, E, F or G. For trailer tires with dual load index values, first load index is for a single tire appliation, and second load index is for a dual tire appliation. Dual tire load capacity value is generally lower due to safety reasons (in case one tire is deflated, the second tire has to carry the load by itself).
Inflating trailer tire over its maximum inflation pressure will not increase its load carrying capacity.
