5 parameters on car tires that drivers need to know
(Baonghean.vn) - By understanding these parameters, you will see the tire life of the car you use every day increase significantly. And this is also a detail that manufacturers do not want you to know by heart.
1.Tire type designation
 |
Tire size specifications usually start with 1 or 2 letters, such as P or LT. These letters tell us what type of vehicle or conditions the tire is intended for... For example LT235/75R15 104/101S/C). This type of tire is for light trucks, cargo pickup trucks, heavy trucks with a load capacity of 750kg to 1 ton. In addition, it can be used for some SUVs or Full-size Vans. |
2. Tire width
 |
Is the contact surface area of the car tire with the road surface. The parameter is located right after the tire type symbol. It is the distance from one sidewall to the other sidewall of the tire measured in millimeters. For example, P 225/45R17 91V, this is a tire with a width of 225mm. The width of the tire can be converted to inches; a P225 tire corresponds to a width of 8.86 inches. |
3. Tire structure
 |
For example, P225/45 R17 91V. This is a tire with a radial structure (symbol R - abbreviation of radial). According to statistics, 98% of current tires have a radial structure. In addition, there is a diagonal structure (symbol D - Bias). In addition, we can see the symbol B, the structure is similar to the diagonal structure but has an additional layer of reinforcing belts under the tire tread. |
4.Speed limit index
 |
For example, tire P225/45R17 91 V, the letter V indicates the maximum speed limit that the tire can operate at is 220km/h. In addition, there are other indexes from M to Z corresponding to maximum speeds from 130 to more than 240km/h. |
5.Limit load index
 |
Since 1991, all tire manufacturers have been required to specify the load capacity limit on their tires. For example, the P225/45R17 91V tire has a load index of 91, which corresponds to a weight capacity of 615 kg. Typically, load indexes range from 71 to 110, which corresponds to a weight capacity of 345 kg to 1060 kg... |
