Is the production date on Bridgestone tires indented or raised?
3 Answers
It is normal for Bridgestone's production date to be indented. The production date on tires is formed through mold hot pressing, which can result in either indented or raised dates, and Bridgestone's production date is marked as indented. Introduction to Bridgestone: Bridgestone is a globally renowned tire manufacturer with 51 factories in 23 countries and sales in over 150 countries. The company was founded by Shojiro Ishibashi. The company's English name is derived from the literal translation of the founder's surname, Ishibashi. Bridgestone's corporate philosophy: To provide people with a safe and comfortable life, creating joy and emotion, and striving to become a trusted, beloved, and proud enterprise—this is the corporate philosophy of the Bridgestone Group.
I remember first noticing the production date on Bridgestone tires during a car maintenance check—it was always indented. Specifically, you look for the small four-digit imprint on the tire sidewall, like '1123' representing the 11th week of 2023. This is because the mold stamps it during production, and the rubber forms a recessed mark as it cools, making it resistant to wear. I’ve checked Bridgestone tires multiple times, and they all follow this design—the indented imprint is also more durable, ensuring it remains visible even after prolonged driving or car washes. For car owners, regularly checking this date is crucial, as tires aged 6-10 years are prone to aging and cracking, especially on highways where the risk of a blowout increases significantly. Personally, I check my tire dates every six months to ensure safe driving. Bridgestone’s standardized approach aligns with most major brands—reliable, no-nonsense, and reassuring.
As someone who's spent a long time in auto repair shops, it's common to see Bridgestone tire production dates indented. It's determined by the mold manufacturing process: during tire injection molding, the engraved characters on the template create recessed impressions, making the numbers clearly visible, typically located on the sidewall near the hub area. If they were protruding, they'd be more susceptible to being worn down by dust or stones. I've seen countless Bridgestone tires, and the date is always indented there - for example, the first two digits of the four-digit code represent the week, and the last two represent the year. This isn't unique to Bridgestone; other brands like Michelin do the same. Car owners should get used to checking this because expired tires harden, affecting grip and braking distance. I recommend taking a quick look every time you change the oil - it's simple and could save your life. Also, if you encounter severe wear or bulging, replace them immediately - don't hesitate over the cost.
