Operation CHARM: Car repair manuals for everyone.

Tire Age




NOTE: tires should not be older than 6 years. Not even the spare wheel.


The age of the tire can be determined via the manufacturer's code, which is listed behind the DOT code on the tire sidewall. The date of manufacture (the last four digits) is located at the end of the code.

Example

DOT DM CP 05 Y 2200 22 = production week
00 = production year 2000
