When one tyre of the twin-configuration is flat, the other tyre carries the extra load, which may result in damage to both tyres.

1. Regrooving can extend the tyre life by 25%; 2. Regrooving can improve tyre’s grip and water dissipation for better safety.

1. Check tyre pressure and make necessary adjustments. Ensure the correct tyre pressure, extend the tyre’s mileage and increase your chance of retreadability; 2. Check on the tyre damage, perform professional repair if necessary. This will extend tyre life and increase the chances of retreadability;

1. Over-inflation increases sensitivity to cutting and tearing and centre wear on drive axle 2. Under-inflation causes excessive casing deflection and heating of the tyre; 3. Results in tyre scrap and mileage reduction.

Tread depth difference between tyres installed on the same axle should be within 5 mm. This can ensure the steering, handling, stability and safety.
