The sidewall provides valuable information about the tire including the specifications, the brand, and the type of construction. All numbers are standardized and recognized by tire manufacturers around the world.
Load index corresponds to the load capacity while speed rating is designated using letters from J to Z and represents the maximum speed of the tire. These two factors are interdependent. Please refer to the tables below for the load index and speed rating.
Run flat tires also known as safe tires or zero pressure tires are designed to perform after a puncture or complete loss of tire inflation pressure has occurred. These tires allow you to drive up to 80km at 80km/h to help you reach a safe place.
Summer thunderstorms produce water on road surfaces and causes tire skidding.
Proper Tire Pressure Is Important.
Leads to: air leaks, flat tires, shorter tire life, and affects safe travels
Leads to: reduced handling, braking, and water dispersion abilities
Leads to: uneven tire wear, reduced handling and comfort, increased fuel consumption, and even tire blowouts
When faced with complex road conditions, do you know how to choose the right tires for your car?
Selecting Suitable Tires for Different Road Conditions is Essential!
Fine Tread Pattern (HT)
Comfort Low Noise
Exaggerated Tread Pattern (MT)
Strong Off-Road Capabilities
Rough Pattern with Attention to Details (AT)
Balancing Off-Road Capabilities and Comfort
Every tire is designed with a tread wear indicator (TWI) which is a raised section molded into the grooves of a tire. In passenger car tires, the TWI is around 1.6 mm and the tire shoulder is labeled with TWI or the △ symbol.
TWI indicates the tread wear limit and helps vehicle owners understand the tread wear so they know when to replace the tires. When the tread is leveled with the TWI, the tread pattern will be separated and the tires need to be replaced immediately.Note: When tread wear limit is reached, handling, braking, and water evacuation will significantly be decreased. Extremely dangerous!
Please replace tires immediately to avoid tire blowouts
Increases probability of tire leak
Tire shows signs of deterioration
If your tires have any of the conditions mentioned above, it is recommended that you visit the nearest Giti Professional Service Center to replace the tires!
The sidewall of a tire contains information for your safety and knowledge. Being able to read sidewall markings will help you better understand the performance of each tire and provide information for mounting and servicing the tire.
Under specified conditions, speed rating is a letter representing the maximum speed at which the tire can carry a load corresponding to its load index (except for passenger car and motorcycle tires with speeds greater than 210 km/h).
Under specified conditions, load index is a numerical code representing the maximum load the tire can carry corresponding to its speed rating (except for passenger car and motorcycle tires with speeds greater than 210 km/h).
Speed rating is represented with a letter from J to Z and is the maximum speed corresponding to its load index.
