Just wanted to point out that you need to know the volume of air (tire size) to equate inflation pressure with load capacity.
Wheels have specific inflation limits which usually relate to the rim flange strength. The load capacity is usually limited by the disk portion of a wheel (where bolt holes are). Since these are two different portions of a wheel they are not tired to each other.
Hope this clears up the confusion.
The reference Herk cited is from the wheel specs. Specs:
•Rim dimensions: 15" diameter x 6" wide
•Bolt pattern: 5 on 4-1/2"
•Wheel bolt size: 1/2"-20
•Pilot diameter: 3.19"
•Load rating: 2,150 lbs at 65 psi
•Limited 1-year warranty
Has nothing to do with tire size or volume of the tire itself. It merely states that the wheel will take a load of 2150 with 65psi of air in some size tire. Clearly the limit on the wheel.
