Tyre Test Checklist Like the car body, tyres can be used for a long time only if they are managed properly.
Ensure safety while also extending the lifespan of your tyres through the ‘Tyre Test Checklist.’
1. Is the air pressure proper?
If a tyre is used without having sufficient air pressure, much heat is generated from the tyre. Thus, it causes separation of the rubber and code besides the code disconnection and tyre rupture. Also, the edge of the tyres is worn-out easily shortening the life of the tyres. Meanwhile if a tyre is used having excessive air pressure, the tyre is always under a state of tension. For this reason, the tyre 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 tyre is worn out fast shortening the life of a tyre.
2. Are there any tyres that are abnormally worn-out (Partial abrasion)?
To prevent an abnormal abrasion, the air-pressure and wheel alignment should be checked regularly and the tyre position
should be replaced after driving 8,000~10,000km for even abrasion of the tyres (The tyre replacement may be adjusted depending on the worn-out condition).
3. Are there any tyres below than Treadwear Index (TI) (Depth of the left dent: 1.6mm)?
If a tyre 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 tyre is operated having an alien substance, such as a nail or stone, inside the tread dent, the tyre may be punctured or rupture. Presence of tyre damage shall be checked in the tyre store and any damaged tyres 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 tyres?
For a spare tyre, the air pressure, presence of damage, and abrasion state must be checked in regular base for its instant use when needed. Any old tyres 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 tyre by the irregular load distribution. Meanwhile, the heat generated by the friction at the rim and bead part of a tyre damages the code.
