How to Check the Production Date of Car Glass and Tires?
2 Answers
To check the production date of car glass and tires, follow these methods: 1. The production date of car glass is indicated by small dots and numbers. The dots represent the production month, and the number represents the production year. If the dots are before the number, it means the production date is in the first half of the year. Subtract the number of dots from 7 to get the month. If the dots are after the number, it means the production date is in the second half of the year. Subtract the number of dots from 13 to get the month. 2. The outer side of car tires will have a DOT mark, and the last four digits of this mark indicate the production date of the tire. Some cars are special, such as BMW, whose glass does not have black dots. If you want to know the production date, you need to enter the serial code on the glass and check it on a specialized website.
Regarding checking the production date of car glass, I've looked it up many times myself, and it's quite easy. There's usually a small mark in the corner of the glass, such as dots with a number. The number indicates the year, for example, '23' means it was produced in 2023; the dots represent the month. Dots before the number indicate the first half of the year, and dots after indicate the second half. For instance, one dot in the first half means January, up to six dots for June. Tires also have a date code. Look for the DOT mark on the sidewall, and the last four digits indicate the production date: the first two digits represent the week of production, and the last two digits represent the year. For example, '0923' means the 9th week of 2023. I always check when changing tires or buying a car to avoid safety hazards from aging car parts. After all, old glass is prone to cracking, and old tires are more likely to blow out. Regular checks can extend their service life. I recommend checking during routine car maintenance—don't wait until something goes wrong. Safety first, especially after rain when the rearview window gets blurry, you'll understand its importance even more.
