What is the pressure of truck tires?
2 Answers
Here is the pressure of truck tires: No uniform standard: Depending on different usage environments, tire model standards, layers, or actual specifications, trucks have different tire pressure value standards that are not uniform. Pressure: For tires below 825, the pressure should not exceed 10 bars; for steel-belted tires above 825, the pressure should not be less than 12 bars. For tire model 650, the pressure is 6.5 bars, and for 750, it is 7.5 bars. Below is extended information about truck tires: 1. Meaning of numbers: The first number indicates the tire section width, and the latter represents the rim diameter, measured in inches. 2. Example: For instance, 205/55R19 indicates a radial tire with a section width of 205 mm, an aspect ratio of 55, and a rim diameter of 19 inches.
I remember when driving a truck for long distances, tire pressure always needs to be maintained within the appropriate range. Generally, light trucks require around 32 to 35 PSI, but the exact value depends on the sticker by the door or the manual. Before each load, I always use a pressure gauge to measure the cold tires—pumping them to the upper limit when fully loaded and reducing it appropriately when empty. In summer, the pressure naturally rises due to heat, while in winter, it's the opposite, requiring regular checks and adjustments. Ignoring this makes the ride bumpy and uncomfortable, and fuel consumption becomes ridiculously high. This isn't just about saving money—it's fundamental for safe driving.
