By Perry J Zucker
When a tire failure occurs on a moving vehicle, there could be catastrophic events. Depending on which tire had failed, the vehicle could moment (2) in a specific direction and/or another, within a fraction of time. Ideally, the operator of the vehicle, should be experienced in this type of situation, to achieve the best outcome. Some tire(s) failures are cause by road hazards, under or over inflated tire(s), manufacturers defects, worn threads, and age of tire(s); dry rot, which may not be visible from the outside of the tire, etc. Therefore, it is extremely important that the date of the tire is read as well as noted.
Manufacturer's Date Code (Age of Tire) - 2000 and newer
Beginning in the year 2000 and newer, all tires should have a manufactured date coding (Federal Regulations) somewhere on the side wall. Some retailers / wholesale shops / garages sell / install tires, that are new, in the terms of never being installed on any vehicle, but were manufactured years prior to. Most vehicle manufacturers (OEM) recommend to take out of service, the tire(s) from use, regards of the mileages, between 4 - 7 years, as well as examining the thread wear.
Tire Manufacturers Date - Decoding - Expert
The last 3 to 4 digits after the DOT insignia is basically the date code. The "WW", is the week of the year, e.g. 31, is the 31st week of the year and the "YY" is the year of the decade, e.g. 08, is year 2008.
Conclusion - Tire Failure - Expert
When considered purchasing new tires, verify the date code (Manufactured) within 12 months) before finalizing the sale.
Secondly properly maintain the tire by maintaining the air pressure (as per manufacturer), thread conditions, thread depth and the age of all the tires, which might prevent some tire failure and accidents.
