How to check the production date of tires and windows when picking up a new car: 1. Vehicle windows: a. The production date of vehicle windows is composed of small dots and numbers, where the dots represent the production month and the numbers represent the production year. b. If the dots are before the number, it indicates 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 indicates the production date is in the second half of the year. Subtract the number of dots from 13 to get the month. 2. Vehicle tires: a. The DOT mark is usually embossed on the outer side of vehicle tires, and the last four digits of this mark can indicate the tire's production date. b. The production date of vehicle tires is displayed in the format AABB, where the first AA represents the week number and the latter BB represents the production year.
When picking up my new car, I specifically learned this trick from an experienced driver. The tire date is hidden in the last four digits of the DOT code on the sidewall. For example, 2519 means the tire was produced in the 25th week of 2019. The glass date is even more hidden, usually marked with dotted numbers in the corner, like ·8·. Here, the number 8 represents the year 2018, and the dots in front indicate the month by subtracting the number of dots from 7. In this case, 7 minus 2 equals May. Remember to check the car's manufacturing date first. It's normal for tires and glass to be a few months older than the car, but if the glass date is later than the car's, it must have been replaced. Bring your phone to take clear photos of these codes during inspection, and study them carefully later for peace of mind.
