Can tires produced four or five years ago still be used?

[DiJulianna]

Tires produced four or five years ago cannot be used. Tires are rubber products and will age on their own even if not used. Continuing to use them poses a risk of blowouts. Tire shelf life: Generally, tires should not be kept in storage for more than 3 years from the date of production, and should not be used on vehicles for more than 8 years. Tire replacement cycle: The service life of car tires is four years or 80,000 kilometers, whichever comes first. If there are more than 5 damages, early replacement is required. If there is damage on the sidewall, even one instance requires replacement. If the car frequently travels on rough roads and the tires show severe wear, early replacement is necessary.
