The tire load rating changes with tire pressure because of tire compression. When loading a vehicle, the tire’s volume decreases, increasing the pressure. The spec plate shows two pressure values: one for normal use and one for loaded use. Adjust the tire pressure based on vehicle specifications for optimal safety and performance.
When tires are inflated to their recommended pressure, they achieve optimal load rating performance. If the inflation is either too low or too high, the load rating does change, compromising safety. This is why it is crucial to regularly check tire pressure, especially before long trips or when carrying heavy loads.
Regular maintenance helps in sustaining the correct tire pressure and load rating. Drivers should adhere to manufacturer specifications found on the vehicle’s door jamb or owner’s manual.
Now that we understand the relationship between tire pressure and load rating, we can explore how different driving conditions and load types affect tire performance and safety further.
