1. Rated load

When choosing tires, the first thing to ensure is that the tires cannot be overloaded. Tires of the same specification may have different load capacities. When selecting, attention should be paid to the following factors: firstly, tires of the same specification have different structural layers, so their load capacities are also different. Secondly, tires of the same specification have different allowable loads when used as single tires and when installed together as dual tires. When installed together as dual tires, due to the curvature of the road surface and the downward bending deformation of the axle after loading, the load on the inner and outer tires is not the same. At this time, the total load capacity of the two tires is about 1.72 times that of the single tire state, not twice the relationship.

2. Production date

The production date of the tire is also very important. A string of four digits can be seen near the wheel hub, with the first two digits being the production week and the last two digits being the year of production. If you buy a tire that has been stored for a long time, it may age and affect its performance.

3. Avoid refurbishing tires

When purchasing, it is important to avoid retreading tires as much as possible. The method of identifying retreaded tires is simple, and the most common is to observe the color and luster of the tires. Refurbished tires have a dull color and luster, leaving fingerprints when touched. Therefore, do not blindly purchase such tires.

At the same time, there are some raised marks on car tires that indicate the tire model and performance. These are also the breakthrough points for identifying refurbished tires. The marks on refurbished tires are reattached after refurbishment, while the marks on brand new tires are integrated with the tires. The identification method is to scratch these marks with fingernails. Generally, these marks on refurbished tires are not tightly attached, and those that can be removed are undoubtedly refurbished tires.

4. Pay attention to tire type

When choosing tires, it is also important to be careful not to mix different types of tires, such as combining tires that are more suitable for off-road vehicles with tires for regular cars, or mixing directional sports car tires with regular tires.

5. Tire cushioning performance

Tires must have good cushioning performance, absorbing and buffering vehicle vibrations together with the suspension. If the cushioning performance of tires is poor, it will affect the ride comfort of the vehicle and also affect the life of other parts of the vehicle.

6. Tire noise

During tire driving, noise will be generated. Tires with different structures and patterns will produce varying levels of noise at different speeds, and sometimes the noise can reach an annoying level.
