Trucks and buses, unlike passenger cars, significantly differ in weight, mileage and operating conditions. They shall carry bigger load and be equipped with tyres having characteristics appropriate for the particular vehicle category. Therefore, there are tyres specially designed for trucks.
Their design can be radial or bias. The most up-to-date and promising are radial. They have a number of advantages in comparison with the performance characteristics of bias. Cord threads in design of these products do not intersect, they are located along the tire, parallel to each other, reducing shear deformation of rubber and ensuring longer service life. Due to reduction of carcass plies the heat dissipation is improved. Tyres provide higher mileage, better wear resistance and handling as well as lower fuel consumption.
Cord threads of bias tyres are located diagonally from side to side. Due to thicker sidewall they have better impact strength. In addition, they are remarkable for durability on bad roads or in heavy road conditions.
Bias and radial truck tyres can be tubeless and with tube. Tube tire consists of a tire, a tube and a rim strip that protects the tube from wearing down on the rim and pinching by the tire beads. Instead of tube, the tubeless tyres have the inner liner vulcanized to the inner side of the tire. The shock absorbing ability of a tire is determined by the air pressure in the tire and the tire elasticity.
The sidewall of the truck tire has markings with complete information (country of manufacture, model, trade mark, size, certificate numbers for compliance with international rules and standards, date of manufacture, etc.).
They may vary depending on the size.
For example, the size 11,00R20 150/146 K means:
Type of truck tyres:
Letter symbol indicates application.
Tyres are mounted on trucks according to their application on the steering or driving axle, etc., as they differ in their technical characteristics and operational properties. In order to avoid premature truck tire failure, poor handling, etc., do not mount tyres different in design and parameters on the same axle.
The performance properties of the car depend on the tread pattern. It shall correspond to the properties of the road surface.
Depending on the tread pattern, truck tyres are divided into road, multi-purpose and all-terrain. Road are recommended to be used on improved permanent road surface, multi-purpose – on permanent roads and roads with thin surfaces, all-terrain vehicles – in off-road conditions and on deformable soils.
Driving style affects the operational life of the tire as much as technical factors. It is necessary to observe the load requirements provided by the manufacturer. Otherwise, you’ll contribute to reducing the overall performance properties of the tire – intensive tread wear, etc.
Check the pressure in tyres every two weeks. The pressure shall be measured in a cold tire. Otherwise, it will be out of service much earlier.
Balance the wheels when first mounting tyres, when there are signs of uneven wear and after repair.
When replacing or interchanging tyres, follow the rules of installation and disassembly to avoid mechanical damage.
Tyres shall be replaced
after 5 years of operation or when the tread is worn to a level of
