Recently, a tire boss roast that some car owners choose the latest tires when they buy them.
They are not interested in tires with longer inventory and believe that tires stored for 2-3 years become "expired tires".
Is that really the case?
How should tires be stored, what are the factors that affect tire performance, and how long does it take for a tire to be considered "expired"?
It is inaccurate to say that tires expire in 2-3 years
At present, there is no standard in the world to determine the expiration date of tires,
Because the damage to each tire depends on various factors such as temperature, load, tire pressure, speed, and even the road conditions on which the tire is used.
Therefore, it is highly inaccurate to hastily assume that tires have expired after only 2-3 years of storage, especially since these tires are stored in a good environment and have not been affected by any of the factors mentioned above.
South Korea and Germany conducted comparative tests on new tires and tires with three years of inventory, respectively.
The results indicate that the difference in performance between new tires and tires that have been stored for three years can be ignored.
The view of the British Rubber Manufacturers Association is that tires that are 10 years old or older from the date of production must be replaced or disposed of.
Tire storage temperature is crucial
The European Technical Organization for Tires and Wheels (ETRTO) recommends storing tires at a temperature not exceeding 35 ° C.
A study in Saudi Arabia found that tires stored at 50 ° C age twice as fast as tires stored at 40 ° C and four times faster than tires stored at 30 ° C.
In fact, tire shops can explain the issue of inventory tires to car owners without worrying about "expiration".
