In the good ole’ USA, big business lobbies against consumer rights and quite often wins.
Why would the big tire manufactures want to pull their tires off the shelf to be destroyed?
It pays to be an informed consumer, both in terms of finance and safety.
If you’re driving on a tire with this format, it’s time to retire it.
Example of a tire manufactured before 2000 with the earlier Tire Identification Number format: 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). Most tire manufacturer’s warranties cover their tires for four years from the date of purchase or five years from the week the tires were manufactured.
Therefore, it is possible to see a Tire Identification Number that appears incomplete and requires looking at the tire’s other sidewall to find the entire Tire Identification Number The use of a partial Tire Identification Number on the one sidewall (shown above) reduces the risk of injury to the mold technician that would have to install the weekly date code on the top sidewall portion of a hot tire mold.
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.
So if you purchase new tires that were manufactured exactly two years ago they will be covered for a total of six years (four years from the date of purchase) as long as you have your receipt.
If you lose your receipt, your tires’ warranty coverage will end five years from the week the tire was produced (resulting in the tire manufacturer’s warranty coverage ending only three years from the date of purchase in this example).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).Believe it or not, you can actually determine your tire’s manufacture date based on these codes.Let’s discuss pre and post 2000 tire manufacturing date stamps (if your tire is older than this as indicated by a lack of this standard, you’ll want to have it replaced immediately).Another thing to note when getting new tires or checking your old is that all four tires will most likely not be the exact same age.
