Load index and speed rating are sometimes not mandatory for flotation sizes, but must be for any tire approved for street and highway use. 2- or 3-digit number: Load index; see table below. 1- or 2-digit/letter combination: Speed rating; see table below. Additional marks: see subheading below.
The wet grip index (WGI) is calculated from the results of two tests specified in the regulations. The first test measures the maximum achievable average deceleration of a vehicle as it slows from 85 ± 2 km/h (52.8 mph) to 20 ± 2 km/h (12.4 mph). The second test (the "skid trailer" test) is usually performed using a tow vehicle and trailer.
These represent the tire's resistance to the generation of heat at speed. Tires graded A effectively dissipate heat up to a maximum speed that is greater than 115 mph. B rates at a maximum between 100 mph and 115 mph. C rates at a maximum of between 85 mph to 100 mph. Tires that cannot grade up to C or higher cannot be sold in the US. [9]
If you are still alive ;-) the letter is the speed code -- the number is the load rating.

You likely have to raise the PSI.

The Fortescue railway uses 68 kilograms per metre (140 lb/yd) rail on concrete sleepers and has a maximum axle load of 40 t (39 long tons; 44 short tons), which as of 2008 was the highest axle load of any railway in the world. [1] In 2011, it was proposed to increase the axle load of the railway to 42 tonnes (41 long tons; 46 short tons).
