What are the specifications and models of heavy truck tires?

The specifications and models of heavy truck tires are 12.00-20-18PR. The following is an introduction to the relationship between tire pressure and vehicle performance: 1. Tire pressure and load capacity: Tire pressure is an indicator of a vehicle's load capacity. The tire pressure of a vehicle determines its load capacity. The higher the tire pressure, the greater the load capacity; the lower the pressure, the smaller the load capacity, provided that the tire pressure is within the standard range. 2. The relationship between tire pressure and vehicle power performance: When a tire operates on a flat road, it needs to overcome the resistance from the ground and air. When the tire pressure decreases, the rolling resistance coefficient increases rapidly, the tire deforms during rolling, and fuel consumption rises. Appropriate tire pressure ensures good power performance of the vehicle. 3. The relationship between tire pressure and vehicle ride comfort: The ride comfort of a vehicle is directly related to passenger comfort. Appropriate tire pressure can provide better comfort for passengers. When the tire pressure is too high, the tire becomes hard, the vibration frequency of the vehicle increases, and ride comfort deteriorates. Proper adjustment of tire pressure ensures the ride comfort of the tire.
Heavy-duty truck tire specifications and models are quite important. I've been driving heavy trucks for over a decade. Common specifications like 11.00R22.5 - the 11.00 represents the tire width in inches, R stands for radial construction, and 22.5 is the rim diameter in inches. For models, the Michelin X Multi D is an excellent choice for drive wheels, specifically designed for long-haul highway use with strong traction. For steer wheels, the Bridgestone M729 model works well with its shallower tread pattern for better handling. Different applications require different specifications - heavy-load models need 12.00R24 tires with a load index above 150 for safety. I once used the wrong specification and experienced rapid tire wear plus shipping delays. The lesson: always follow the manual's specified models - don't make random changes. Regular pressure checks maintain proper inflation, significantly extending tire life. Safe driving starts with attention to details.
