To quickly determine if industrial tires are aging, three methods can be used: checking the production/use date, visual inspection, and physical testing. If any one of these characteristics is present, aging can be determined. The specific methods are as follows:

1. First, check the production/use date for a preliminary assessment:

Rubber aging in industrial tires is irreversible. Tires manufactured more than 5 years ago and used for more than 4 years, even if they appear normal, are considered to be in a critical aging state and require close inspection. Industrial tires for new energy vehicles, due to their greater weight, age even faster; tires older than 4 years require increased vigilance.

2. Observe the visual signs of aging for direct identification:

Aging tires have very obvious visual signals. Focus on these areas:

Cracks on the sidewall/tread grooves: This is the most typical aging characteristic. Fine, net-like or radial cracks first appear on the sidewall, gradually extending to the bottom of the tread grooves. If the crack depth exceeds 1mm and the internal cords are visible, the aging is severe.

Color and Texture Changes: New tires are normally matte black, but as they age, they turn grayish-white, and oxidation spots may appear on the rubber surface. Inferior tires may also become sticky and flake off in powdery form.

Bulging/Structural Damage: Aging causes the internal tire cords to become brittle and break, leading to localized bulges on the tire sidewall. This is a very dangerous type of aging damage and can cause a tire blowout at any time.

3. Simple Physical Tests to Confirm Elasticity Changes:

Aging causes rubber to lose elasticity. Two simple methods can be used to test this:

Insulation Test: Press firmly on the tire sidewall with your finger. If it becomes noticeably hard, rebounds slowly, and leaves an indentation that doesn't disappear quickly, it indicates a significant decrease in rubber elasticity, signifying aging. Normal tires will rebound quickly after being pressed, feeling soft and elastic.

Driving Experience Assessment: Aging tires will significantly increase the bumpiness of the ride, lengthen braking distances under heavy loads or on wet roads, and noticeably reduce grip. These factors can also help determine aging.
