Under normal use, the aging cycle of industrial tires is about 3-5 years, and the specific aging rate can vary several times depending on the material, environment, and usage habits. The following is a detailed analysis of the influencing factors:

1. Basic aging cycle

Ordinary rubber material industrial inflatable tires have a standard aging start-up cycle of 3-5 years under standard operating conditions. After 5 years of use, rubber oxidation will enter the acceleration stage, and the risk of tire blowouts will significantly increase.

Industrial solid tires contain anti-aging agents in their formula, with a normal aging cycle of 3-10 years. The aging rate of high-end polyurethane materials is much slower than that of ordinary rubber.

Even if the tires are not installed for use, the shelf life of idle storage is only 3 years. It is not recommended to purchase tires that have been out of the factory for more than 3 years, as the rubber has already begun to age naturally.

2. Core influencing factors

(1) The greatest impact on the usage environment

Temperature and Light: Working in a high-temperature and sun exposed environment for a long time will accelerate the oxidation rate of rubber, and the aging rate will be 30% -50% faster than in a cool environment, directly shortening the service life by half. In high-temperature areas with an average annual temperature above 30 ℃, the safe service life of tires will be shortened from 5 years to 3 years.

Road conditions: Working on rough gravel roads such as construction sites and mining areas for a long time, the tires are continuously impacted and rubbed, which not only wears out faster, but also increases the aging rate by 40% compared to flat roads, and the service life may be less than 3 years.

Corrosive environment: Contact with oil stains and chemical corrosive substances can directly damage the rubber structure and accelerate aging and cracking.

(2) The influence of usage habits

Long term overloading: It will cause the tires to continuously bear excessive stress, accelerating the aging rate by 30% -50%.

Speeding: Driving beyond the design speed will cause the tire temperature to continue to rise, accelerating rubber aging and degradation.

Intense operation: Frequent rapid acceleration and sudden braking can cause the tires to repeatedly deform and generate heat, increasing the aging rate by 15% -30%.

Abnormal tire pressure: Both too low and too high tire pressure can cause uneven stress on the tire, local abnormal heat generation, and accelerate aging.

(3) The influence of material formula

The wear resistance and anti-aging performance of high-end polyurethane industrial tire is 3-4 times that of ordinary rubber, and the anti-aging life under ideal conditions can exceed 8 years.

The formula added with benzimidazole antioxidant can directly extend the anti-aging life of tire, and the aging speed is about 20% slower than that of the formula not added.
