Tires and Rims (Part 1) Quality Garage Thanh Phong Auto Hcm 2024


Tires (tires) are installed on the vehicle along with the rims (rims). Vehicles running on pneumatic tires are maintained inflated by air pressure. Tires are the only part of the vehicle that comes into direct contact with the road surface.

If the air pressure in the tire is incorrect, it can cause tire wear and reduce the tire's ability to generate power.

Tires perform the following functions:

  • Support the entire weight of the vehicle.
  • Directly in contact with the road surface, thereby transmitting driving and braking forces to the vehicle, thereby controlling direction change, acceleration, deceleration, parking and turning.
  • Reduces vibrations caused by bumps in the road surface.


Tires include tubeless tires and tubeless tires. In addition, there are also radial tires and diagonal tires, both types have the following parts:

Tires include Tires with Tubes (Inner Tubes) and Tires Without Tubes

Tire treads are molded in many styles both to facilitate drainage and to cope with factors depending on the conditions of the road surface and the type of vehicle being used.

3.1. Vertical rib pattern

The near-vertical pattern consists of a number of zigzag grooves running along the circumference of the tire. This type is most suitable when driving on asphalt roads at high speeds and is used in many types of cars, from passenger cars to buses and trucks.


  • Minimize tire rolling resistance.
  • Greater side-slip resistance benefits vehicle control.
  • Reduce tire noise.
  • Traction is somewhat inferior to lug-type tires.

3.2. Lug style

The grooves in the lug pattern are approximately perpendicular to the outer ring of the tire. Commonly used on construction machinery and truck tires, this tread pattern is suitable for off-road use.


  • The lug pattern provides good traction
  • The rolling resistance of the tire is slightly high
  • Lower horizontal sliding resistance
  • The tread in the lug area may wear unevenly
  • Tire noise is louder

3.3. Vertical ribs and lugs combined

This type of combination creates stable running performance on both paved and unpaved roads


  • The lug pattern along the tire's centerline makes the vehicle more stable by reducing lateral tire slippage, while the lug pattern on both sides of the tire's centerline improves steering and braking performance.
  • The lug portion of this style is prone to uneven wear

3.4. Block style

In this type, the tread is divided into independent blocks. Used on most snow tires and lugless tires, currently the block tread pattern is used on radial tires for even passenger vehicles.


  • Provides superior steering and braking performance.
  • Reduces sliding and spinning on muddy or snow-covered roads.
  • These types of tires often wear out faster than longitudinal rib and lug tires.
  • Rolling resistance is slightly greater.
  • This type of tire tread is susceptible to abnormal wear, especially when driving on hard surfaces.

Tire Patterns
Tire Patterns


These are tires with tread patterns oriented in the direction of rotation. The horizontal grooves in the tread indicate the direction of rotation. Increases performance on wet roads, making it drain easier. The performance of these tires will be impaired if installed in the wrong direction.

Tire tread noise is the most clearly heard noise of the tire when the vehicle is running. The tread grooves in contact with the road surface have air entrained and compressed between the grooves and the road surface. When the tire tread leaves the road, compressed air bounces out of the grooves, causing noise.

Tire Tread Noise Depends on Tread Pattern
Tire Tread Noise Depends on Tread Pattern

Tread noise increases if the tire tread is shaped to attract more air into the grooves. For example, block or lug tread patterns may generate more noise than longitudinal rib patterns. The frequency of the noise will increase as the vehicle's speed increases.

Since tire tread noise depends on the tread pattern, it can be designed to minimize this noise. For example, based on the repeated installation of lugs and longitudinal ribs.
