Tips for Tire Management Tire management and inspection are the fundamentals of safe driving.
Tire Test Checklist Like the car body, tires can be used for a long time only if they are managed properly.
Ensure safety while also extending the lifespan of your tires through the ‘Tire Test Checklist.’
1. Is the air pressure proper?
If a tire is used without having sufficient air pressure, much heat is generated from the tire. Thus, it causes separation of the rubber and code besides the code disconnection and tire rupture. Also, the edge of the tires is worn-out easily shortening the life of the tires. Meanwhile if a tire is used having excessive air pressure, the tire is always under a state of tension. For this reason, the tire may be ruptured and cut easily in case of having an external impact. Also, a vehicle tends to skid when pressing the break and the middle part of the tire is worn out fast shortening the life of a tire.
2. Are there any tires that are abnormally worn-out (Partial abrasion)?
To prevent an abnormal abrasion, the air-pressure and wheel alignment should be checked regularly and the tire position should be replaced after driving 8,000~10,000km for even abrasion of the tires (The tire replacement may be adjusted depending on the worn-out condition).
3. Are there any tires below than Treadwear Index (TI) (Depth of the left dent: 1.6mm)?
If a tire below Treadwear Index (TI) is used, a vehicle is easily skidded as the breaking distance becomes longer. Also, it tends to be ruptured when an alien substance is pierced and generate hydroplaning causing difficulty in breaking and handling operation.
4. Are there any damages?
If a tire is operated having an alien substance, such as a nail or stone, inside the tread dent, the tire may be punctured or rupture. Presence of tire damage shall be checked in the tire store and any damaged tires must be replaced to a new one in case when the damage threatens the safety of carcass.
5. Is there any abnormality on the spare tires?
For a spare tire, the air pressure, presence of damage, and abrasion state must be checked in regular base for its instant use when needed. Any old tires mustn’t be used.
6. Are the wheels balanced well?
The poor wheel balance causes difficulty in driving as the handle shakes and discomfort while driving. Also, it generates partial abrasion and severe noise.
7. Is there any damages on the wheels?
The damaged wheel is the cause of an accident as the air-pressure is released. It also causes rupture of a tire by the irregular load distribution. Meanwhile, the heat generated by the friction at the rim and bead part of a tire damages the code.
