Total Tire Age: Recommended Maximum is 10 Years
The total age of a tire refers to its technical age from the date of manufacture, which is marked on the tire’s sidewall as a four-digit code in conjunction with the DOT marking. According to international standards, the recommended maximum total age of a tire is 10 years.
Tire Usage Age: Recommended Maximum is 6 Years
The usage age of a tire refers to its age from the time it is first used. Determining an exact maximum usage lifespan for a tire is difficult, as wear and aging depend on many factors. However, according to international standards, the recommended maximum usage age of a tire is 6 years.
Summer Tires
The tread depth of the main grooves in summer tires must be at least 1.6 mm. The main grooves are the wide grooves located in the central area of the tread, covering approximately three-quarters of its width. It is prohibited to modify or deepen the tread grooves of a passenger car tire.
For driving in wet conditions, a safety recommendation suggests a minimum tread depth of 4.0 mm. If the tread depth falls below this recommendation, it is advisable to consider replacing the summer tires and drive with extra care in rainy conditions. However, this safety recommendation does not mean that the tire has reached the end of its lifecycle if the tread depth is below 4.0 mm.
Winter Tires
Winter tires must be used from the beginning of November to the end of March whenever weather or road conditions require them. Winter tires can be either studded or non-studded, and their main groove tread depth must be at least 3.0 mm.
For driving in snowy and icy conditions, a safety recommendation suggests a minimum tread depth of 5.0 mm. If the tread depth falls below this recommendation, it is advisable to consider replacing the winter tires and drive with extra care in harsh winter conditions. However, this safety recommendation does not mean that the tire has reached the end of its lifecycle if the tread depth is below 5.0 mm.

Tire Origin
Most of the tires we sell come from the second sets of wheels from redeemed vehicles, meaning they were not installed on the vehicle at the time of the incident that led to the redemption. If a vehicle was not involved in an accident, the tires are classified as used. Additionally, the tires may originate from decommissioned vehicles’ second sets or from other insurance claims involving tires, rims, or complete wheel sets.
