Properly inflating truck tires to the correct pressure is crucial for ensuring safety and operational efficiency. Incorrect tire pressure can lead to tire blowouts, increased fuel consumption, and reduced tire lifespan. So, how do you inflate truck tires correctly? This article from Xe Tải Mỹ Đình will provide you with essential information about truck tire inflation, including standard pressure and important considerations.
Key Considerations for Truck Tire Inflation
Regularly Check Tire Pressure
Regularly checking your truck tire pressure is very important and should be done at least once a month or more frequently if the vehicle often travels long distances. This helps ensure safety, saves fuel, and extends tire life.

Use an Accurate Tire Pressure Gauge
Use a specialized and high-quality tire pressure gauge to get accurate readings. Avoid using your hand to check tire hardness, as this method is inaccurate and can lead to incorrect inflation pressure.

Avoid Over- or Under-Inflating Tires
Over-inflating tires in hot weather can cause tire blowouts due to temperature and friction increasing the pressure inside the tire. Conversely, under-inflating tires increases the contact area with the road surface, leading to higher fuel consumption, faster tire wear, and reduced vehicle control.

How to Read Truck Tire Sidewall Markings
Each tire has technical specifications printed on its sidewall. Understanding these markings will help you determine the correct inflation pressure for your vehicle. For example, the code “P225/70R16 102T” indicates:
- P: Passenger car tire type. The symbol “LT” indicates a light truck tire.
- 225: Tire width (mm).
- 70: Aspect ratio (sidewall height as a percentage of width).
- R: Radial tire construction.
- 16: Rim diameter (inches).
- 102T: Load index and maximum speed rating.

Understanding Truck Tire Pressure Specifications
Typically, the maximum tire pressure for truck tires is around 8 bar (8 kg/cm2 or 116 PSI). However, the actual inflation pressure depends on the vehicle’s load and should be about 5% lower than the maximum pressure. Refer to the manufacturer’s guidelines for recommended pressure for each vehicle type and load capacity.

Important Notes on Truck Tire Pressure
Although the maximum pressure (Max. Press. PSI) is marked on the tire, you should not inflate to this level. The recommended pressure is usually lower to ensure safety and operational efficiency. Maximum tire pressure typically ranges from 110 to 135 PSI, and the actual inflation pressure should be adjusted according to the vehicle’s load.
