Is a car tire that's almost a year old considered a stock tire?

Fast one-year-old tires are stock tires. Here is more information about tires: 1. The role of tires: (1) Tires must ensure that the car has good ride comfort and driving smoothness. (2) Tires are crucial for the safety of drivers and passengers, so they play a very important role in the use of vehicles. 2. Tire selection: (1) If you focus on wear-resistant and multi-purpose tires, you can choose Pirelli STR, which is a semi-urban, semi-off-road SUV tire suitable for various road conditions. (2) If you focus on handling performance, you can choose Bridgestone HP-SPORT, which is a sporty urban SUV tire. (3) If you focus on comfort performance, you can choose Continental CCC-UHP, which is a comfort-oriented SUV tire.
Tires that are almost a year old can indeed be considered a form of stock tires, as rubber materials naturally age over time, even if they have never been mounted on a vehicle. I've personally researched the tire aging process, which is primarily caused by oxidation, making the rubber harder and more brittle. To determine if it meets safety standards, first check the DOT code on the tire sidewall: the last four digits indicate the production week and year. For example, '3523' means the tire was produced in the 35th week of 2023. A tire that's almost a year old may still be within its usable lifespan if stored properly—such as in a dark, low-temperature environment—but any signs of aging, like fine surface cracks or a dry texture, should absolutely be avoided. In practical applications, tires stored for over two years show significant performance degradation, including reduced grip and an increased risk of blowouts. I recommend proactively asking the dealer about the production date when purchasing a car and prioritizing tires manufactured within the last six months to ensure driving safety. After all, tires are the foundation of driving and should never be overlooked.
I once helped a friend deal with an issue with stock tires. He bought a tire that was almost a year old, and initially thought it was fine, but after a few months of use, he started noticing problems. Tire rubber degrades over time; the longer it's stored, the more likely it is to harden, especially under the high temperatures of summer, which accelerates deterioration. Checking the production date is simple: look for the last four digits of the DOT code, for example, '1823' means it was manufactured in the 18th week of 2023. A tire that's almost a year old isn't too bad, and if stored in a garage away from direct sunlight, it might hold up, but it's crucial to regularly check for cracks or discoloration. If signs of aging are obvious, it's better to replace it to avoid potential issues. I often advise car owners to choose reputable shops when replacing tires and to request newer batches to avoid old stock—safety first can also save you from future troubles and expenses.
Tires that have been in stock for almost a year can still be considered in inventory, but they don't necessarily need to be scrapped immediately. When I changed my own tires, I noticed that the rubber hardens over time, even if unused. Checking the last four digits of the DOT code, such as '0124', indicates production in the first week of 2024. Tires nearly a year old might still be usable but are affected by storage conditions. If there are cracks or poor gloss, replace them without hesitation as severely aged tires pose high risks. When selecting tires, choosing fresh ones produced within the last six months is the most reliable option.
