How old can the production date of new car tires be?

[EthanLee]

New car tires are generally fine if their production date is within 3 years. Here are the details: 1. Definition of stock tires: Tires that have been in storage for over 1 year after production are considered stock tires. However, this also depends on the tire's service life. Typically, all-season or economy tires have a service life of 3-5 years or about 50,000 kilometers. 2. Checking tire production date: To identify a tire's production date, you need to understand how to read the date code on the tire sidewall. It usually appears as a 4-digit number following the DOT code (a series of letters and numbers). The last four digits indicate the production date - the first two digits represent the production week, and the last two digits indicate the production year.
