51-250: Check out The Tyre Load Index Chart

Tyre load index or tyre load rating is just a numerical code on a Tyre sidewall that specifies the most load the Tyre can hold when inflated at its maximum permitted cold pressure, under certain service conditions – specified by the manufacturer.

The strain index is identified as the main tyre size designation or the tyre’s service description, along with the speed index.E.g., tyre size designation: 205/60R15 91V – 92V in “service description” means this tyre can hold a maximum load of 630 kg/1389 lb(load index is 92) and it sustains the maximum speed of 240 kmph/149 mph(speed index is V).

Tyres with exactly the same load index, irrespective of tyre size, may carry exactly the same load, but not at all times, and they might require substantially different inflation pressures. The same or greater load index does not at all times match equal or greater load capacity at all inflation pressure settings, particularly when you compare P-metric and Euro-metric passenger car tyres.

Light truck tyres mostly utilize the term Load Range that’s marked on a tyre with a letter, to denote the most load-carrying capacity of the tyre.
