What is load rating C on tires?
For example, a “C” load range indicates that a tire is equivalent to a 6-ply construction tire. This tire isn’t actually built with 6 plies, but rather one or two plies of equivalent strength. Both have a 4-ply rating, but the Extra Load can support additional load at up to 42 PSI while the Standard Load is 36 PSI.
What’s the difference between load range C and D?
The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The D rated tire has a higher capacity. For a ST175/80D13 like # AM1ST77, the capacity is 1,610 pounds at 65 psi. For a C load range in the same size, like # AM1ST76 , the capacity is 1,360 pounds at 50 psi.
