Pirelli Production Dates

Can someone post how to decypher the production date code on the P7's.

Can someone post how to decypher the production date code on the P7's.

 

The Date code is a US regulation set by the DOT. A quick search of the internet will show you how to read it. Note prior to late seventies or eighties something there was no requirement. Then it was a 3 digit code with the first two numbers the week of manufacture and the last number the year. Later they switched to a 4 digit code with the last two numbers being the year. Please verifiy this though, I am going by memory.

Yes, that seems to be correct. Thanks.

Determining the Age of a Tire

 

Tires Manufactured Before 2000

 

The Tire Identification Number for tires produced prior to 2000 was based on the assumption that tires would not be in service for ten years. While they were required to provided the same information as today’s tires, the week and year the tire was produced was contained in the last three digits. The 2 digits used to identify the week a tire was manufactured immediately preceded a single digit used to identify the year.

 

Example of a tire manufactured before 2000 with the earlier Tire Identification Number format:

 

 

In the example above:

DOT EJ8J DFM 408

40 Manufactured during the 40th week of the year

8 Manufactured during the 8th year of the decade

While the previous Tire Identification Number format identified that a tire was built in the 8th year of a decade, there was no universal identifier that confirmed which decade (tires produced in the 1990s may have a small triangle following the Tire Identification Number to identify the decade).

Thanks Mike. I remember now and have passed the info onto a P7 owner.
