Product Description

Tire introduction

Tires are ground rolling circular elastic rubber products assembled on various vehicles or machinery, usually installed on metal rims, used to support the body, buffer external impact, and ensure the driving performance of the vehicle. Tire in the driving process to withstand a variety of deformation, load, force and high and low temperature effects, so it must have a high load bearing performance, traction performance, buffer performance, while requiring high wear resistance and flexural resistance, as well as low rolling resistance and heat generation.

Classification of tires
1. High-performance tires: Designed for high-speed driving scenarios, through soft but strong grip tread, increase traction at high speeds and corners, ensuring smooth operation of the car. However, soft tread can also lead to faster wear, so the frequency of replacement is relatively high.
2. Mud tire: With wide tread and deep and large pattern design, it can effectively prevent the tire from getting into the mud and ensure the grip on the muddy road. However, it brings a sense of turbulence and noise.
3. Snow tires: Use a deeper pattern and soft tread material, combined with additional threads to enhance grip. However, when driving on normal roads, it is noisy and the fuel consumption is relatively high.
The main parameters of the tire
1. Width: the wider the width of the tire, the larger the ground area, the better the grip and traction, but the fuel consumption will increase accordingly.
2. Flat ratio: The ratio of the height from the wheel to the tread to the maximum width measured by the cross-section of the tire, the tire with a large flat ratio has a strong buffer and higher comfort, but has poor feedback on the road surface.
3.R: represents radial tire, its internal cord braid arrangement direction and tread center.

Product Description

First, excellent performance

The advanced rubber formula and innovative pattern design of this tire effectively improve the grip and achieve excellent braking distance on both wet and dry roads, providing a solid guarantee for your driving safety. The unique pattern structure also reduces noise, allowing you to enjoy a quiet and comfortable driving environment.
Two, durable and reliable
The use of high-strength materials to construct the body, with excellent wear resistance, significantly extend the service life of the tire, reduce the cost of use. At the same time, the strengthened side design enhances the impact resistance of the tire to cope with a variety of complex road conditions.
Third, precise control
The optimized tire profile and advanced manufacturing process ensure the stability and precision of the vehicle when driving at high speeds and corners, giving the driver a confident driving experience that perfectly matches your pursuit of driving fun and safety.
Fourth, energy conservation and environmental protection
Carefully designed tires have low rolling resistance, reduce fuel consumption, reduce carbon dioxide emissions, save energy and environmental protection at the same time, but also for you to save fuel costs, is an ideal choice for environmental protection and economic benefits.
Whether you are driving a car, SUV or light truck, [brand name] tires will become the ideal companion for your car with excellent performance and reliable quality, accompanying you on every wonderful journey. line at a 90 degree Angle, suitable for high-speed driving.

Tyre Pattern

Longitudinal pattern

• Features: The direction of the pattern groove is consistent with the direction of the circumference, in a straight line or slightly curved line shape, such as the vertical straight pattern on the common bus tire.
• Advantages: small rolling resistance, can reduce fuel consumption, the vehicle is not easy to slip, can improve the handling performance, often used in cars, light buses and other vehicles pursuing comfort and fuel economy.

Cross pattern
• Features: The pattern groove direction is perpendicular to the circumference direction, is a horizontal groove, similar to the shape of the claw, also known as the claw pattern.
• Advantages: large tire contact area with the ground, excellent braking force, driving force performance, good wear resistance, often used in engineering vehicles such as bulldozers, excavators, etc., but also suitable for vehicles driving in bad road conditions.

Block pattern
• Features: The pattern groove is connected to each other, showing an independent pattern block structure, like composed of multiple block graphics.
• Advantages: Strong grip and traction, can adapt to complex road conditions, such as off-road, mud, snow, etc., commonly seen in off-road vehicles, SUVs and other models.

Single guide pattern
• Features: The pattern has obvious directionality, is arrowhead-shaped or similar shape, the tire block is larger, and the crosscutting groove is less.
• Advantages: small rolling resistance, high speed level, strong handling, good drainage performance, often used in high-speed cars. When installing, note that the arrow direction should be consistent with the rolling direction of the tire.

Asymmetrical pattern
• Features: With the central groove of the tread as the center line, the two sides of the pattern is different, one side of the pattern focuses on drainage and control, the other side focuses on grip and support.
• Advantages: It can improve high-speed cornering performance, increase the landing pressure of the outside pattern during cornering, and improve the handling stability and grip of the vehicle.

Mixed pattern
• Features: The characteristics of a variety of patterns are integrated, usually the longitudinal pattern in the middle is used for rapid drainage, and the horizontal or blocky patterns on both sides increase the grip.
• Advantages: Adapt to a variety of road conditions, not only has good drainage performance, but also has a certain grip and control ability, widely used in cars,buses and trucks.

FAQ

First, tire life is related

• Q: How long do tires typically last?

• A: Tire life is affected by many factors, such as driving habits, road conditions, vehicle load, etc. Under normal circumstances, the mileage of the tire is about 40,000-60,000 kilometers, and the use time is about 3-5 years. However, if you often drive in bad road conditions or have a more aggressive driving style, the service life may be shortened.

• Q: How can I tell if a tire needs to be replaced?

• A: Mainly look at the wear mark. There is a wear indication mark in the tire pattern, the general height is 1.6 mm, when the tire pattern is worn to be flush with this mark, the tire should be replaced. In addition, if the tires appear bulging, cracks or serious rubber aging, they must also be replaced.

Second, tire performance related

• Q: What is the difference between different tire patterns?

• Answer: longitudinal pattern tire rolling resistance is small, good comfort, often used in cars; The transverse pattern tire has strong grip and wear resistance, which is common in engineering vehicles; Block pattern tires have excellent grip in off-road and complex road conditions, which is a good choice for SUV and off-road models; Single guide pattern tires have good drainage and handling, and are generally used for high-performance cars.

• Q: What is the use of the tire speed rating?

• A: The speed rating indicates the maximum speed the tire can withstand under specified conditions. For example, a tire with a speed class of H has a maximum safe speed of 210km/h. The speed of the vehicle should not exceed the speed grade of the tire, otherwise it will be a safety risk.

Third, tire maintenance related

• Q: How to properly maintain tires?

• A: To check the tire pressure regularly, the general car tire pressure is between 2.2-2.5 bar. Also pay attention to the cleaning of tires, to avoid oil, chemicals and other corrosion of tires. At the same time, when the vehicle is parked for a long time, try to choose the flat ground to avoid local pressure on the tire.

• Q: Is tyre transposition necessary?

• A: Absolutely necessary. Because of the different degrees of wear of the front and rear tires of the vehicle, regular transposition can make the tire wear more uniform and extend the service life of the tire, it is generally recommended to transposition once every 10,000 to 20,000 kilometers.
