WHEN purchasing new tires, it is important to look at the four-digit DOT, or Department of Transportation date.
TikTok creator @brandon.haneline created a 42-second video explaining the secrets of car tires.
Titled 'what your local tire company doesn’t want you to know,' the hack video accumulated more than 3million views.
When purchasing a new set of tires, Brandon suggests you pay attention to the DOT number located on the inner tires.
For example, 0521 means the tires were made on the fifth week of 2021.
0219 means it was built the second week of 2019.
Tire companies do not want you to know this because they want to sell you old tires.
"You don't want to buy tires that are already two or three years old," shared brandon.haneline in the video.
The short hack video has reached more than 1,470 comments and 132.5K likes.
One user commented: "Tires do expires because they’re made of rubber, & the older they’re can suffer separation from heat, & cold. The date matter."
