What are the different psi applied on road surface by vehicles?

The pressure exerted by a vehicle's tires on the road surface is measured in pounds per square inch (psi). Different types of vehicles apply different amounts of psi depending on their weight, tire size, and suspension systems. Here are some typical ranges of psi for different types of vehicles:

- Passenger cars: 30-35 psi

- Light trucks and SUVs: 35-40 psi

- Heavy-duty trucks: 80-100 psi

- Motorcycles: 32-36 psi

- Bicycles: 80-110 psi

These ranges are general guidelines, and the actual psi may vary depending on the specific vehicle and its specifications. For example, higher tire pressure may be recommended for heavier vehicles or vehicles carrying heavy loads.

Additionally, some vehicles have a feature called tire pressure monitoring system (TPMS) that alerts the driver if the tire pressure is too low or too high. This helps ensure that the tires are inflated to the correct pressure recommended by the vehicle manufacturer.
