What is the normal difference in tire pressure between the four wheels?
1 Answers
It is impossible for the tire pressure of all four wheels to always be consistent. Generally, the front two tires will have slightly higher pressure than the rear ones, and a difference within 0.1 bar is normal. The following are the reasons for differences in tire pressure: 1. The front and rear tire pressures are inherently different, which is a normal phenomenon related to the vehicle's center of gravity position and drivetrain configuration. Front-wheel-drive vehicles have higher front tire pressure, while rear-wheel-drive vehicles have higher rear tire pressure. 2. According to research data from the "Tire Industry," tire pressure increases with rising temperature. For every 30°C increase in temperature, tire pressure rises by 16.5%, and when the temperature increases by 40°C, tire pressure increases by 19.5%, resulting in variations in tire pressure.
