Excuse me: What kinds of car tires are there? What are their advantages and disadvantages? What types of loading vehicles are suitable for each? thank you

The thick rubber layer in contact with the road surface requires good wear resistance and impact resistance.

Belt (belt)

The steel wire layer that closely connects the tread and the carcass can improve the rigidity of the tread.

shoulder

The part between the tread end and the upper end of the sidewall has the function of protecting the carcass and dissipating the heat generated during driving.

Side wall part

The rubber layer between the lower end of the shoulder and the bead can protect the carcass.

Carcass part

The single-layer or multi-layer rubber-coated cord part that constitutes the tire skeleton needs good impact resistance and flex resistance.

Bead part

The part where the carcass cord is wound and combined with the rim consists of bead steel wire and rubber.

inside

The inner lining of the tire needs good air tightness.

Pattern is not only the decisive factor for the beautiful appearance of the tire, but also related to whether the traction, braking, steering, drainage and noise performance of the tire can be fully exerted. It is mainly composed of grooves, blocks and nodes. Tires have been developed for more than a hundred years, and there are countless patterns, but they can be roughly divided into the following categories.

Stripe pattern: the groove direction is consistent with the circumferential direction.

Advantages: small rolling resistance, difficult skidding, good maneuverability and stability, good high-speed performance, low noise, less heat generated during driving and good driving comfort.

Disadvantages: poor braking performance and wetland stability, easy to crack under load.

Uses: Good road surface, front wheels of trucks and buses.

Horn pattern: the groove direction is perpendicular to the circumferential direction.

Advantages: good braking and handling performance, good traction performance.

Disadvantages: high noise and rolling resistance, not suitable for high-speed driving.

Uses: Dumpers, industrial vehicles and rear wheels of buses running on bad roads.

Compound pattern: it combines the characteristics of strip and trumpet patterns.

Advantages: The stripe pattern in the center of the tread provides good handling performance and prevents side slip. The claw pattern on the tread shoulder provides good traction and braking performance.

Usage: Suitable for all kinds of packaged and unpacked roads, mainly installed on the front and rear wheels of trucks and buses.

Block pattern: the grooves are connected with each other, showing an independent block structure.

Advantages: excellent braking and handling performance, excellent handling and stability performance in snow and wet roads, and good drainage performance in rainy days.

Disadvantages: independent block structure, poor wear resistance.

Uses: All-weather and snow tires for automobiles and rear wheels of commercial vehicles.

Asymmetric tread pattern: The left and right tread patterns are different in shape.

Advantages: As the touchdown pressure of the side pattern during turning is increased, the high-speed turning performance is greatly improved, and the wear resistance of the side pattern is supplemented.

Disadvantages: Be sure to pay attention to the correct installation direction of tires.

Uses: Competitive vehicles and high-performance vehicles.

Single guide pattern: the grooves are connected with each other, showing an independent pattern block structure.

Advantages: excellent braking performance, excellent drainage performance and excellent stability in rainy days, suitable for high-speed driving.

Disadvantages: the tire installation position must be consistent with the driving direction.

Uses: High-speed automobile tires.
