As one of the important components of the vehicle, the tire works with the car suspension to alleviate the impact of the car when it is running, and ensure the car has a good ride comfort and ride smoothness. Ensure that the wheels and the road have good adhesion, and improve the traction, braking and passing of the car. Bearing the weight of the car, tires are very important to the car.
So do you really understand tires? What is the difference between a tire and a tire? How should tires be selected? What kind of tires are there?
Type of tire structure
The structural types of tires are divided into radial tires and bias tires.
radial tire
Radial tire is a structural form of tire, the international code is "R", commonly known as "steel tire". The cord arrangement of the radial tire carcass is different from that of the bias tire. It is nearly parallel to the section of the casing, arranged like the meridian of the earth, the cord angle is small, generally 0 °C, and there is no focus between the carcass cords.
The advantages of radial tires are:
1. The ground contact area is large, the adhesion performance is good, the tread slip is small, and the unit pressure on the ground is also large, so the rolling resistance is small and the service life is long.
2. The wheel crown is thick and has a hard belt lay

2. The wheel crown is thick and has a hard belt layer, which is not easy to pierce, and has small deformation during driving, which can reduce fuel consumption by 3%-8%.
3. Because the number of plies is small and the sidewall is thin, the radial elasticity is large, the cushioning performance is good, and the load capacity is large.
4. Good heat dissipation performance, can adapt to high temperature and high speed driving.
5. Tax incentives: Since January 1, 2001, radial tires are exempt from consumption tax.
Bias tire
Bias tires are also known as ordinary structural tires, codenamed "B". Refers to the pneumatic tire in which the carcass ply and the adjacent layer of the buffer layer are crossed and arranged at an angle of less than 90°C with the center line of the tread. The tire has good longitudinal rigidity and is suitable for moderate-speed running on ordinary roads.
The advantages of bias tires are:
1. The tread and sidewall of the bias tire have high strength and good elasticity after inflation.
2. Strong carrying capacity.
3. Compared with radial tires, the price is cheaper.
Type of tire pattern
1. Straight groove pattern, also known as ordinary pattern, this pattern has excellent tire maneuverability, low rolling resistance, low noise, especially excellent drainage performance, and is not easy to laterally slip.
2. Horizontal groove pattern, the driving force, braking force and traction force of the horizontal groove pattern tire are particularly excellent, and its wear resistance is excellent, so it is very suitable for construction vehicles such as excavators on the construction site. Poor drainage performance.
3. Vertical and horizontal groove pattern, also called comprehensive pattern, it has the advantages of both vertical groove and horizontal groove pattern, so it is more suitable for off-road vehicles.
4. The mud and snow pattern is specially designed for the use of mud and snow.
5. Off-road pattern, off-road pattern is a pattern specially designed to adapt to dry, wet, rugged mountain roads and muddy and sandy roads. Tires with this pattern can be used in a variety of harsh environments and climates.
Numbers and letters on tires
As shown in the picture above, there are a series of letters and numbers on the tire. What do these numbers and letters represent? Don't look down.
First look at the big fat boy at the top of this picture is the logo and name of Michelin tires. There is nothing to say. The English letters PILOT SPORT 4 SUV behind Michelin represent the series of Michelin tires. The tires are the velvet version of the racing 4 SUV owned by Michelin.
Look at the numbers below the tires, 265/45 R 21. The 265 here means the width of the tire is 265mm, the 45 at the back means the sidewall thickness of the tire is 45mm, the R means the tire is a radial tire, and the last 21 means the diameter of the rim is 21 inches .
brand of tires
After talking about the numbers on the tires, let's introduce the brands of the tires.
1. Michelin tires. The Michelin Group is a global leader in tire technology. It was founded with Clermont-Ferrand in France a hundred years ago. During the long process, the Michelin Group invented the first removable tire for bicycles in 1889 and the first pneumatic tire for cars in 1895. Since then, it has continuously invented tire technology and manufacturing.
Advantages: strong quietness, good grip, high drainage efficiency and good stability.
Disadvantages: not wear-resistant, easy to bulge.
2. Goodyear tires. The American Goodyear Tire and Rubber Company was founded in 1898 and has a history of more than 100 years. Goodyear is the world's largest tire company headquartered in Akron, Ohio, USA. The company produces tires, engineered rubber products and chemicals in more than 90 plants in 28 countries.
Advantages: high wear resistance, long life, good grip and strong drainage.
Disadvantages: It is easier to clamp stones, and the noise is relatively large.
3. Continental tires, formerly known as Continental AG (German Continental Group), was founded in 1871 and is headquartered in Hannover, Germany. It is the third largest tire manufacturer in the world and the largest supplier of auto parts in Europe. In 1882 The German Continental Group uses the strong horse Peugeot, which symbolizes speed and passion, as the company trademark, hence the name of the Continental tire.
Advantages: strong comfort, especially quiet.
Disadvantages: general grip, not wear-resistant, short life.
4. Dunlop Tire, a Japanese tire brand, is affiliated to the Sumitomo Consortium. It was originally founded in Japan by the British Dunlop Company. After Japan declared war on the United Kingdom during World War II, the Dunlop Rubber Factory was also annexed by the Japanese hardcore right-wing Sumitomo Consortium. Dunlop, a British company, is good at applying high-tech achievements to sporting goods designed to allow sports players to reach their personal limits.
Advantages: cost-effective.
Cons: Dunlop tires are decent in every way, but not the best in every way.

Recommended for each tire type
Strong mute:
As a world-class tire company, Michelin tires have launched many tires with particularly strong mute effects. The first one is the Boyue PRIMACY LC series tires under Michelin. This tire continues the central idea of Michelin tires: reducing fuel consumption, Reduce carbon dioxide emissions. Although it has a strong mute effect, the speed level can also reach 270 kilometers per hour.
Strong wear resistance:
Since you want to choose wear-resistant tires, Bridgestone is a tire brand that you must consider. The tires recommended for everyone also meet all the characteristics of wear-resistant tires. First of all, in terms of price It is very affordable and can be applied to all economical cars. Although this tire mainly focuses on wear resistance, its quietness and comfort are also acceptable.
Strong grip:
When it comes to strong grip, we have to talk about Pirelli tires. Pirelli tires are the tires with the strongest grip. Many F1 cars and supercars are matched with Pirelli, which is enough to prove the performance of this tire. The tires of the new Pirelli P1 Cinturato series recommended by everyone can be said to be very good at the same price in terms of grip.
Summarize
Having said so much about tires, I believe that everyone has a preliminary understanding of tires, so how to choose tires suitable for your car in the future? Let me tell you a word here, expensive tires are not necessarily the most suitable tires for your car. Be sure to find the best tires for your car.
Finally, I wish you all to find the most suitable tires for your car!
