The code gives a direct calculation of the theoretical diameter of the tire. However, if you own or use recreational vehicles, 15-passenger vans, collector cars, any other vehicles you don’t drive regularly, or if your annual mileage is low, you could be at risk. Tire pressure monitoring systems continuously monitor the pressure in the tires through sensors located in the tires (direct system) or the use of wheel speed and other vehicle sensors (indirect system).

For Load Range "B" tires, ETRTO (ISO-Metric) standards specify the load index rating at an inflation pressure of 36 psi (250 kPa) (table below), while P-Metric standards measure the load capacity at an inflation pressure of 35 psi (240 kPa). [15], While all ETRTO tires of the same load index will have the same maximum load, P-Metric tires with the same load index may have different load capacities depending on the tire size.
