Car Tire Classification? What types of car tires?

According to the inflation pressure, it is divided into: high-pressure tires. The inflation pressure is generally more than kilogram force cm2, the stiffness is large, the buffering performance is poor, and it has been rarely used.

Low-pressure tires. The inflation pressure is generally 2 kgf cm2. With the improvement of cord strength and tire carrying capacity, some tires have inflation pressures of more than kgf cm2, but their cushioning performance is close to that of low-pressure tires, and they are still low-pressure tires.

Ultra-low pressure tires. The inflation pressure is generally less than 2 kgf cm2. According to the tread pattern, it is divided into:

Plain tread tires. There are many length, horizontal, and two-way designs. Ordinary transverse tread tires are suitable for use on poor and gravel roads; Longitudinal tread tires are suitable for use on good road surfaces; Tires with both longitudinal and transverse patterns are suitable for use on both normal and poor road surfaces.

Off-road tread tires. The tread has a large pattern and is suitable for use in mines, construction sites, deserts, loose ground and slush roads. Mixed tread tires.

It is suitable for good pavement, gravel pavement and loose soil pavement. According to the carcass structure, it is divided into: ordinary structure tires.

The cord of the cord layer is laminated and glued together in a cross form, and the carcass is firm and has good lateral rigidity, but the cushioning performance is poor. Radial construction tires. The cord of the carcass is arranged in the form of a meridian, which is orthogonal to the circumference of the outer tire, and the strength is fully exerted.

Radial structure tires have less rolling resistance than ordinary structure tires, good cushioning performance and long mileage. According to the application, it is divided into passenger tires and truck tires. Passenger tires:

For low-pressure tires with an inflation pressure of less than 4 kgf cm2, the ply layer is generally 4 6 layers, and the bead diameter is generally less than 16 inches. Passenger tires are used in cars and light trucks. Passenger tires are developing in the direction of ultra-low pressure.

Truck tires: low-pressure tires with an inflation pressure of more than 4 kgf cm2, the ply layer is generally 10 16 layers, and the bead diameter is generally 16 32 inches. Truck tires are used in medium and heavy trucks, buses and trolleybuses.

Specifications and sidewall markings The nominal outer diameter (d), cross-sectional width (b) and inner diameter of the bead (d) of the tire are the main specifications of the tire, which are generally marked on the sidewall in the imperial system. High-pressure tires are denoted by d b; Low-pressure tires are denoted by B-D. The sidewall also has a code name indicating the type of carcass cord.

In China, m is used to denote cotton cord; Use r to denote rayon cord; Use n to represent nylon cord; G is used to represent the ordinary structure of steel wire cord; z is used to denote the meridian structure. In addition, the sidewall is also marked with tire pressure, maximum load, number of ply layers, brand, date of manufacture, etc. The load capacity of the tire is expressed as "layer", and the layer of the cotton cord tire is the actual number of layers of the carcass cord.

The higher the level, the greater the load capacity. Cords such as rayon, nylon, polyester, steel wire or polyarylamide are all stronger than cotton cords, so the actual number of cord layers in tires made from these cords is not the same as the layer used to mark the load capacity. For example:

6 layers of nylon cord tires are equivalent to 10 layers.

The types of car tires are AT off-road tires, snow tires, all-season tires, semi-hot tires and hot melt tires. Tires are a kind of vehicles or machinery assembled on the ground rolling annular elastic rubber products, tires are usually installed on metal rims, can support the body, cushion external impact, to achieve contact with the road surface and ensure the driving performance of the vehicle. The maintenance methods of tires are:

Move the tires indoors when it rains to avoid water inside; Avoid areas that cause tire scars or deformations; When dismantling the tire for a long time for storage, pay attention to the inside of the tire and stain the ground due to chemical leakage; Do not place next to generators, batteries, etc.

Tires can be classified according to structure: bias tires, radial tires. It can be classified according to the pattern: strip pattern, transverse pattern tires, mixed pattern tires, off-road pattern tires. In addition, it is possible to classify by vehicle type and size.

There are tubeless tires, tubeless tires, bias tires, radial tires.

The types of car tires include AT off-road tires, snow tires, all-season tires, semi-hot tires and hot-melt rental tires.

Tires are a variety of vehicles or machinery assembled with a ground rolling annular elastic rubber products, tires are usually installed on metal rims, can support the body, cushion external impact, achieve contact with the road surface and ensure the driving performance of the vehicle. The maintenance methods of tires include: moving the tires indoors to avoid water inside the tires when it rains; Avoid areas that cause tire scars or deformations; When dismantling the tire for a long time for storage, pay attention to the inside of the tire and stain the ground due to chemical leakage; Do not place next to generators, batteries, etc.

1. According to the classification of cars and species, it can be divided into 8 types:

1. PC car tires;

2. LT light truck tires;

3. TB tires for trucks and buses;

4. AG agricultural vehicle tires;

5. OTR engineering vehicle tires;

6. ID industrial vehicle tires;

7. AC aircraft tires;

8. MC motorcycle tires.

2. According to the inflation pressure

1. High-pressure tires: the inflation pressure is generally more than one kilogram force per kilogram per kilogram of bright centimeters, the stiffness is large, the buffering performance is poor, and it is rarely used;

2. Low-pressure tires: the inflation pressure is generally 2 to kilogram force per centimeter;

3. Ultra-low pressure tires: the inflation pressure is generally less than 2 kgf per centimeter.

3. According to the structure, it is divided into radial tires and bias tires.

Fourth, according to the pattern, it can be divided into strip pattern, transverse pattern tires, mixed pattern tires, and off-road pattern tires.

Off-road tires, snow tires, all-season tires.

Tires are classified according to the type of vehicle, and can be divided into about 8 types. Namely:

PC - car tires;

LT - light truck wheel chain tires;

TB - truck and bus tires;

ag - agricultural vehicle jujube bush tires;

OTR - engineering vehicle tires;

id - industrial stool stool cherry tire;

AC – aircraft tires;

MC – Motorcycle tires.

Hello! Automobile tires are classified according to their structure, and there are two types: bias tires and radial tires. According to the pattern, it can be divided into strip pattern tires, transverse pattern tires, mixed pattern tires, and off-road pattern tires.

However, we usually classify some special tires according to the characteristics of use.

High-performance tiresIn pursuit of the ultimate driving pleasure, owners of high-performance sports cars often go to tuning shops to replace them with tires with better grip and handling, which are called high-performance tires. Its rubber adopts a different formula from ordinary tires, and the tread and tread have high design requirements, such as Michelin's pilotsport3 and pilotsupersport.

Snow tires Snow tires have softer rubber for better grip when driving in the snow, and installing snow tires can prevent the vehicle from skidding in harsh winter conditions. These tires often carry pictographic mountain and snowflake logos.

Muddy tiresThe mud tires are large in size, so they are not easy to get stuck in the mud and cannot extricate themselves, and because the pattern adopts an open design, the mud can be quickly discharged. Centrifugal force can be used to keep debris away from the surface of the tire when the wheels are turning, preventing clogging.

Run-flat tires are also known as "run-flat tires" by many people, but this kind of tire only has a small chance of a puncture, and it is not that it will not puncture. Run-flat tires have thickened sidewalls to maintain their original shape for a distance in the event of a run-flat tire, allowing the driver to drive the car to the nearest service point. Hope it helps.

Tires can be divided into radial tires and bias tires according to the classification of internal structure, and the arrangement of the internal ply layer of radial tires is parallel to each other, and the circumference of the center of the tire crown is at an angle of 90 degrees. At present, basically all cars use radial tires.

Classification by tire tread.

Tires can be divided into four types: strip pattern tires, transverse pattern tires, mixed pattern tires and off-road pattern tires according to the surface pattern classification.

Classification by tire type.

Tires can be classified into 8 types according to the type of vehicle. PC - passenger car tires, LT - light truck tires, TB - truck and bus tires, AG - agricultural vehicle tires, OTR - engineering vehicle tires, ID - industrial vehicle tires、—— aircraft tires, MC - motorcycle tires.

By applying climate classifications.

According to the classification of tires, there are three types of tires: winter snow tires, summer tires and all-weather tires.

According to the carcass structure, it can be divided into pneumatic tires and solid tires. According to the different composition structure, it can be divided into two types: tubeless tires and tubeless tires; According to the working pressure in the tire, it can be divided into three types: high-pressure tires, low-pressure tires and ultra-low-pressure tires; According to the different directions of the cord arrangement in the carcass, it can be divided into ordinary bias tires, bundled bias tires and radial tires. According to the different tread patterns, they can be divided into ordinary pattern tires, mixed pattern tires and off-road pattern tires.

There are many standards for the classification of automobile tires, including four categories, which can be classified according to structure, pattern, model, and specifications. The details are as follows: according to the tire structure, the tire can be divided into radial tire and intelligent bias tire according to the internal structure.

The inner layers of the radial tires are arranged parallel to each other and at an angle of 90 degrees to the circumference of the center of the crown. At present, all cars on the sky are basically using radial tires. By Tire Tread:

Tire blindness can be divided into four types according to the surface pattern: stripe tires, horizontal tires, hybrid tires, and off-road tires. By vehicle type:

Tires can be divided into 8 types according to vehicle types, namely PC-car tires, LT-light truck tires, TB-truck and bus tires, AG-agricultural vehicle tires, OTR-engineering vehicle tires, ID-industrial vehicle tires, AC-aircraft tires and MC-motorcycle tires. According to the tire size, it can be divided into giant tires, large tires, medium tires, small tires and mini tires.

Classified by car type.

Tires are classified according to the type of vehicle, and can be divided into about 8 types. Namely: PC - car tires; LT - light truck tires; TB - truck and bus tires; ag - agricultural vehicle tires; OTR - engineering vehicle tires; ID - Industrial vehicle tires; AC – aircraft tires; MC – Motorcycle tires.

Classified by tire use.

Tires are classified by application, including truck tires, passenger car tires and mining tires.

Categorized by tire size.

Tires are classified by size, generally referring to tires with a cross-sectional width of more than 17in (inches, 1in 25 4mm) or more, which belongs to giant tires; Tires with a cross-sectional width of less than 17 inches and more than 10 inches belong to large tires; Tires with a tire section width of less than 10 inches belong to small and medium-sized tires.

Classified by tire tread.

There are many types of tires classified by tread, but they can be broadly divided into five types:

Straight groove pattern, also called ordinary pattern. This pattern has excellent stability in manipulation, low rotational resistance, low noise, especially excellent drainage performance, and is not easy to slide laterally. The reason why it is called an ordinary pattern is relative to the off-road pattern and the mud and snow pattern.

In fact, there are many types of common patterns, because each large tire manufacturer has its own laboratory and tire testing field, and countless engineers and technicians study patterns there. However, in the process of research, some patterns focus on tranquility and comfort, some patterns focus on waterproof and anti-slip, some patterns focus on grip, and some patterns focus on low fluctuation resistance and fuel saving. Therefore, although it is only a narrow tread, there are 10,000 variations, which can be really said"Between square inches, the world of thousands of flowers"。

And every big manufacturer is constantly introducing new patterns every year.

Groove pattern. The driving force, braking force and traction of the cross groove pattern are particularly excellent, and its wear resistance is excellent, therefore, it is very suitable for the use of engineering vehicles such as bulldozers and excavators, but the maneuverability and drainage performance of the cross groove pattern are poor.

Longitudinal and horizontal groove pattern. The longitudinal and horizontal groove pattern is also called the comprehensive pattern, which has the advantages of both longitudinal groove and horizontal groove pattern, therefore, it is also more suitable for off-road vehicles such as Jeep, such as the 750-16 tires used by the original Sanling Jeep factory in Japan, which is this longitudinal and horizontal groove pattern.

Tires are classified according to the type of vehicle, and can be divided into about 8 types.

Namely: PC - car tires; LT - light truck tires; TB - truck and bus tires; ag - agricultural vehicle tires; OTR - engineering vehicle tires; ID - Industrial vehicle tires; AC – aircraft tires; MC – Motorcycle tires.
