Other tyre I do not know but ATS can keep more than 18 months 1. you can see from the box, because box color changed after 12 months 2. you can compare the hardness with same degree tyre 3. you can check the hardness by tyre meter ( this is the best way but only for manufacturer because the cost for this tyre meter is more than Euro500) 上文只是本人的建議 |
