How to Check the Production Date of Yokohama Tires?
2 Answers
Yokohama tires indicate the production date in the same way as other tires. According to regulations, the production date is marked on the tire. On the sidewall of the tire's outer side, the last four digits of the DOT code provide the production date information. It consists of four digits "AABB". The first two digits "AA" indicate the week of the year the tire was produced, while the last two digits "BB" represent the year. Below are some considerations when purchasing tires: 1. When selecting tires, try to choose those with earlier production dates, as the lifespan of tires is generally around 3 years. Beyond this period, tires begin to age. 2. The main signs of tire aging are the appearance of fine cracks on the surface, followed by cracking. Aged tires lose their elasticity, and continued use can lead to tread deformation, increasing the risk of a blowout.
I just got a new set of Yokohama tires and checked their production date yesterday. It's simple: look for a DOT code on the tire sidewall, the last four digits are key. For example, if you see '3723', the first two digits (37) represent the 37th week, and the last two digits (23) mean 2023, indicating the tire was produced in September 2023. I think this is important because tires age, and after 5 years they're prone to cracking or reduced grip. Yokohama tires are good quality, but I still regularly check tire pressure and tread depth - they should be replaced when worn to 6mm minimum. Remember not to park in direct sunlight for too long, as it shortens tire life. In daily driving, I use my phone flashlight to inspect the sidewalls every three months to avoid overlooking safety hazards - safety always comes first.
