What's the pressure on the low pressure tire?
Because of the development of the skeleton material, the load of the tyre increases remarkably, and the corresponding pressure increases. For example, the 14 tier 9:00-20 nylon bias tire load is 21.428kN (2185kgf), the corresponding pressure is 0.0657MPa (6.7kgf/cm2), while the tire cushioning performance is roughly the same as the original specifications of tires. They are usually classified as low pressure tyres.
Please inflate the tire pressure recommended by the car plant. You can find the tire pressure recommended value of the vehicle in the user manual or the cab door (near the B column), the fuel tank cover, the storage tank and so on, marked with the tire type.The recommended tire pressure is usually the tire pressure measured under the condition of cooling.A tyre cooling condition is defined as a minimum of three hours after parking or a tire running no more than 2 km. If you can only measure the tire pressure during the hot tire, please subtract the measured tire pressure value by about 0.3 bar (= 4psi), that is, the tire cooling and charging pressure.
Low pressure tire has good elasticity, wide cross section, large contact with road, thin wall and good heat dissipation. These characteristics improve the vehicle ride comfort, steering control stability. Tire depression, after heating expansion is small, relatively safe
Pneumatic tyres with inflation pressure of 0.1471 ~ 0.490MPa (1.5 ~ 5kgf/cm2) are called low pressure tires
