How to Check the Tire Date on a New Car?
2 Answers
On one side of the car tire, there will be a set of numbers, and the last four digits of this marking can indicate the production date of the tire. 1. The production date consists of four digits "AABB", where the first two digits "AA" represent the week of the year (normally one month equals four weeks), and the last two digits "BB" indicate the year. For example, if the last four digits are 4117, it means the tire was produced in the 41st week of 2017. 2. Tires, like other parts of a car, have a certain lifespan. If they reach a certain age or mileage, they need to be replaced in time. Otherwise, it may lead to insufficient grip, weakened performance, and ultimately directly affect driving safety.
When checking the manufacturing date of new car tires, I first crouch down to inspect the sidewall of each tire, where there's always a DOT code section. Locate the last four digits of that number group – for example, 3823 indicates the tire was produced in the 38th week of 2023. The date code might be on either the inner or outer side of the tire, so you'll need to rotate the tire for a thorough check. The production date of new car tires should be close to your vehicle delivery date, preferably no earlier than six to nine months prior to prevent dealers from using old stock. I also make it a habit to take photos with my phone and zoom in for inspection since the imprinted characters can be small – this makes documentation easier. Don't overlook this during new car delivery; spending five minutes can prevent future aging issues, as tires deteriorate and become brittle even when stored unused for extended periods.
