How to Appropriately Store Tyres

Tyres naturally degenerate over time*1. However, it is possible to extend the life of a tyre by paying attention to the factors that lead to degradation when storing tyres. *1 Rubber weakens year-by-year and cracks start to appear on the tyre surface as degradation advances.

Seven points to remember for tyre storage

1 Reduce air pressure to around half the specified level*2 You can lessen the burden on the rubber and minimize degradation and cracking by removing air from a tyre. *2 Tyre air pressure specified for each car.

2 Store tyres on flat ground and still attached to the wheels We recommend keeping the tyres attached to the wheels as this helps avoid distortion in shape. You can lay the tyres on top of each other on flat ground, but be careful that the shape of the tyres underneath does not become distorted. The lateral face of the tyres may become distorted if you lay them on top of each other, so we recommend storing them vertically.

3 Avoid direct sunlight Ultraviolet light causes rubber to degenerate. Store tyres in a dark place under cover to avoid direct sunlight.

4 Avoid rain and moisture This can cause the rubber to deteriorate and the steel cord inside the tyre to rust.

5 Avoid heat and oil Rubber absorbs oil, so make sure the tyres are wiped clean before storage. Also, hot environments accelerate rubber degradation, so be sure to keep the tyres in a cool place.

6 Avoid electric sparks from equipment Ozone from motors or batteries causes rubber to crack.

7 Do not store directly on the ground Make sure the tyres are not touching the ground by placing cardboard or a wooden board between them and the ground.
