Causes:

Over inflation
Rim width is too narrow (tires and rims do not fit each other)
Rear wheel drive vehicles centralize load bearing on rear tires

Impact on Tires:

Tread center wears quicker than shoulders, reducing tire life
Enhances tire rigidity but decreases cut resistance and comfort level
Likely to cause sudden tire blowouts due to foreign impact
Increases braking distance, weakens grip, decreases safety

Solutions:

Deflate the Tire: use a tire pressure gauge to deflate the tire until the pressure reaches the recommended level set by the vehicle manufacturer. The recommended tire pressure can be found in various areas of the vehicle such as: car owner’s manual, driver’s side door, and fuel filler door.

The pressure should be checked after the tire cools down (at least 3 hours after stopping or traveling within 2 km).

What Causes Rapid Shoulder Wear on One Side?

Causes:

Incorrect camber angle or toe

In order to achieve maximum tire life, please check the suspension system and perform proper wheel alignment.

to the top

Causes:

Under inflated tires or overloading
Frequent braking or sharp turns
Tire and rim do not match or rim is too wide

Impact on Tires:

Inner and outer shoulder wears quickly, reducing tire life
Leads to higher tire temperature, reduces tire durability, and causes accidents
Increases rolling resistance and fuel consumption

Under inflated tires – tire shoulder bears most of the load.

Solutions:

Inflating to the proper tire pressure (measured with a tire pressure gauge). The recommended tire pressure can be found in various areas of the vehicle such as: car owner’s manual, driver’s side door, and fuel filler door.
Make sure tire and rim fit each other
Good driving habits, avoid abrupt stops and acceleration

The pressure should be checked after the tire cools down (at least 3 hours after stopping or traveling within 2 km).

What Causes Irregular Tread Wear?

Causes:

Vehicle anti-lock braking system (ABS) fails
Brake or tire lock
Loose bearings or components
Improper wheel balancing
Deformed or off centered rims
Chemical contamination

Impact on Tires:

Affects Tire Life

Solutions:

1. Please perform tire balancing and wheel alignment checks
2. Please perform suspension or steering system checks

to the top

Main Causes:

Poor vehicle suspension system will cause the tire surface to appear uneven and rough. In severe cases, the tread pattern will appear feathery.

Common Causes:

Incorrect toe in
Poor vehicle suspension system

Solutions:

1. Please perform tire balancing and wheel alignment checks
2. Please perform suspension or steering system checks


Results in Rapid Wear on Front Axle Tires:

Large positive camber will cause feathering and outer shoulder wear
Large negative camber will cause feathering and inner shoulder wear


Impact on Tires:

Affects tire life.

Solutions:

Vehicle needs to perform wheel alignment and suspension system checks.

Factors That Affect Tire Life:

Driving habits and styles
Tires paired with correct vehicle model
Different road surfaces
Vehicle and tire maintenance
Improper wheel alignment
Braking system error

Impact on Tires:

Affects tire life.

Solution:

To achieve maximum tire life, please check the suspension system and perform proper wheel alignment.

Causes:

Driving with insufficient air pressure for long periods
Tread cuts, punctures, or improper repairs

When tread separation occurs, replace tires immediately.


What Is the Appropriate Tire Pressure for My Car?

The recommended tire pressure for each vehicle is set by the car manufacturer and can be found in various areas of the vehicle such as: car owner’s manual, driver’s side door,fuel filler door, and etc.

Vehicle load and tire pressure is interrelated.For larger loads,please increase the tire pressure.

Please check the tire pressure when the tire is cooled to obtain a more accurate measurement. In other words, when the vehicle has been traveling for less than 2 km or parked for at least 3 hours.

When the tire crown exposes steel cords, the tires should be replaced immediately.

Causes:

Internal tire structural damage.

When driving, the tire shoulder or sidewall is impacted by foreign objects (e.g. potholes and curbs) which causes the tire casing cord to break. The internal tire pressure combined with the weakness in the sidewall causes bulges to form at the area of weakness.

How to Prevent Tire Bulges:

1. When mounting tires, visit a professional tire shop that uses professional equipment and procedures
2. Avoid driving on poor road conditions for long periods and reduce speed on poor roads to help minimize the impact of foreign objects (e.g. potholes)
3. Try not to hit obstacles when going on the curb or parking
4. Develop good tire maintenance practices such as performing regular tire pressure checks to make sure proper pressure is used

Causes:

Scratched by sharp objects (curb, stones, metal fragments, and etc.)

Solutions:

1. Avoid road obstructions
2. Go to the nearest service center to repair tire scratches and avoid further damage

Prolonged exposure to direct sunlight, high temperature, heat, and generators will deteriorate tires. At the same time, oil, gasoline, and other substances will also cause deterioration.

Parking the vehicle outside for long periods, hinders anti-aging properties from being released.

to the top

Causes:

When traveling on the road, sharp objects impact the tire crown and cause the steel belt to break and corrode leading to a deformed tire casing and abnormal tread wear.

When the tire crown exposes steel cords, the tires should be replaced immediately.

Directional Tread Pattern:

Usually has a V-shaped pattern and sidewalls are marked with tire rotation direction
Must be mounted in the same rotation direction marked on the sidewalls
If all four tires are the same size, directional tires can only be rotated vertically (front-back)

Symmetrical Tread Pattern:

Usually has a continuous rib or block design with the same features on both inner and outer tread
Wavy pattern
If all four tires are the same size, symmetrical tires can be rotated diagonally, horizontally, or vertically

Asymmetric Tread Pattern:

Have unique patterns on both sides of the tread. Outer tread usually has larger grooves for better water dispersion and increased wet handling while inner tread usually has smaller grooves to increase contact area and improve grip
Sidewall markings identifying inner and outer side of tire
If all four tires are the same size, asymmetric tires can be rotated the same way as symmetrical tires with care given to the inner and outer tire markings

to the top

Causes:

Tire reaches wear limit and must be replaced when the tread depth is 1.6 mm or leveled with the TWI (Tread Wear Indicator).

Solution:

Take your vehicle to the nearest Giti Professional Service Center for a tread depth inspection.
