Scroll down to the Load Index and Load Carrying Capacity to answer your specific question.

Good and correct information.
RE the specific max tire load capacity ALL DOT approved tires have a statement "Max load 3,000Lbs at 80psi" or something similar. Usually down on the sidewall near the wheel. Statement also gives loadin Kg and inflation in Kpa.
Since it is the inflation that supports the load you have to inflate to the stated level to support the stated load.
