Dating tires

The last two numbers identify the year of manufacture (e.g., a tire with the information "DOT XXXXXXX2714” was manufactured in the 27th week of 2014).For tires manufactured prior to the year 2000, three numbers instead of four indicate the date of manufacture.This particular tire was made the 35 At Tires-easy we consider the tire warranty to begin from the date of purchase, not the DOT Date Code.This means if you purchase new tires today, and the DOT Date Code was a year ago, your warranty still begins on the purchase date, not the manufacture date of the tire.

The chronological age of any tire can be found on the tire sidewall by examining the characters following the symbol "DOT".

I used to think, “the tread looks great, no bald or worn out spots, these things could last at least a couple more years”.

They may last another three years, but your tread has little to do with it. Tires are made of rubber, obviously, and when rubber gets old, it starts to dry and crack (often times from the inside out – this process is not always visible to the naked eye).

I thought it was all in the tread and visible cracking.

I also had no idea that tires have a manufacture date stamped on them.
