What's the tire pressure of a big truck?
According to your model and the total load, there is no absolute pressure, 1100R20 and 1200R20 are generally between 9.5 and 13.5.The more goods, the proposed air pressure can be increased appropriately, less goods, it is recommended less RBI gas. Please refer to.
Other answersAir pressure according to tyre type.You didn't say the model, the specification, this can't give you the answer.For example, the radial tyres of 1200R20 are different in tire pressure.Suppose a brand is marked 1 over load, generally will hit more than 1.3
1, tire pressure standards are not all cars are common. Each vehicle has its own standard.2, you can refer to your car user manual, there are detailed notes.3, you can refer to the relevant parts of the vehicle (such as the main driver's cab related parts), to find relevant annotations.4, you can find the relevant parameters directly on the tire (pressure standards), according to its standard filling appropriate pressure.5, you can go directly to the official website query, with detailed description of the vehicle parameters.D, so too high or too low will bring varying degrees of wear and tear, poor handling and other unsafe factors. According to the third requirements, according to the correct way or standard filling, to ensure that the tire pressure in the normal state, make driving safer.
A, each car of the vehicle, whether large trucks or small cars will have its special tires with conditions or standards, not all vehicles are used as tire specifications, even tire pressure is the same!B and tire pressure standards vary according to the tire design, structure, tire level, brand quality, and so on.
