What is the pressure of truck tires?
2 Answers
Here is the pressure of truck tires: 1. No uniform standard: Trucks have different tire pressure standards according to different usage environments, tire model standards, layers or actual specifications, etc. 2. Pressure: For tires below 825, the pressure should not exceed 10; for steel wire tires above 825, the pressure should not be lower than 12. For tire model 650, the pressure is 6.5; for 750, it is 7.5. Below is extended information about truck tires: 1. Meaning of numbers: The first number indicates the tire section width, and the latter one indicates the rim diameter, in inches. 2. Example: For example, 205/55R19 means a radial tire with a width of 205 mm, an aspect ratio of 55, and a rim diameter of 19 inches.
Having driven trucks for over a decade, I've gained deep experience with tire pressure matters. Generally, truck tire pressure should be determined based on load - typically around 7 bar when fully loaded, and 6 bar when empty, but always refer to the vehicle's label (usually found on door frames or fuel caps). Overinflation causes rapid tread wear during bumpy rides and increases blowout risks, while underinflation leads to excessive tire deformation, fuel consumption spikes, and safety hazards. I make it a habit to check monthly using a pressure gauge on cold tires at dawn. Road conditions matter too - highway driving requires slightly higher pressure for stability. The key is flexible adjustment without cutting corners, as this directly impacts vehicle longevity and safety.
