the ones on my stock are 2505. im in the clear!

oh god, now i gotta check.. >.<

......gotta love ABC and american news. Im sorry, but tires dont have a experation date. Tires will over time decay just due to dry rot, but thats mainly because of UV rays attacking the rubber or excessive heat. The number they say to check, thats the DOT #. Its the date of when they made the tire..so if it says like for example, 2505..it means it was made in the 25th week of 2005. Tires do not expire. This is why u see guys out there with all original muscel cars from like 1968 with the original tires that still run down the road. The only time that tires will go bad is if they are dry rotted, or are bald. Thats it. For example...semi truck tires...most of the ones on the road now have over 2 million miles on them. Same set..why? they get revulcanized, in other words, retredded. I know a trucker whos been running the same set of tires since 1988. I have worked in the automotive trade since i was pretty much 15...i have worked at 3 different tire shops, i have worked as a tire installer 5 times. Tires DO NOT expire. Dont worry about it.

for claification on what dry rot is...

thats dry rot. The sidewall and or tread cracking. This is caused by improper use, long exposure to heat, lots of weather exposure without driving and long exposure to UV rays. Example of how this can happen is if you park your car for a year in your driveway under a car cover or a tarp. The UV will be hittin them in the exact same spot all the time, aswell as if it rains, the moisture will get trapped under the car cover or tarp and as the water starts to evaporate, it will take some of the moisture out of the rubber in your tires, causing these cracks.

Your best bet if you wanna keep your tires for a long time, inflate them properly (use a good gauge, not the one attached to the pump at your local gas station), dont drive too agressively, and put tire shine on. It has chemicals in it that will moisturize the rubber preventing dry rot. Its like a leather couch, u put conditioner on it to prevent it from cracking, same thing with tireshine on ur rubber.

Just because you hear somethin on the news, doesnt make it true. I seriously wanna know how many of the people or writers at ABC have ever done any work on their own car or have worked in a trade. Just be media literit

I tired checking mine, but instead was only able to find a code that contained letters AND numbers.

^^
well i've nvr worked in auto industry.. but i don't think it's just abc saying it... tire rack has it too:

as for the code having both letters and numbers... you mean the last for characters contain letters and numbers?

that code is a DOT #. It included the production date, and manufacturing plant aswell as batch #. the numbers they say to look at is the production date.

EDIT: if you read through the article, it doesnt say they expire..it says that because of weather, driving conditions, sunlight exposure, usage and storage conditions accelerate the aging of tires..ie cause dry rot, and they RECOMEND gettin your tires inspected every 5 years to make sure they are still in good working condition. It doesnt say they expire, it says exactly what i said b4. Tires dont really expire, but they do age and rot and there are variating factors that will tell how long a tire will last. There is nothing in the article saying that any body says they expire, it just says that in europe, they will refuse tires over 6 years old to be on the road, and that Japan wants tires inspected every 5 years to make sure they are road worthy.

so..once again...TIRES DO NOT EXPIRE BUT THEY DO ROT OUT OVER TIME AND WITH HELP OF ENVIROMENTAL FACTORS BUT TIRES DO NOT!! EXPIRE

wow i never knew this,gonna check my out

How do u mean they dont "expire" of course they do just like any living natural life form the cells in the rubber breakdown and die over time. Even if u kept a tire in a case with perfect conditions even with all the carbon in it it would breakdown over time.

Agreed. However, 18 Wheeler companies dont retread. To much of a liability. its also part of most insurance companies that they have new tires or they wont cover damage. atleast thats how it is in the states

Slick. Tires do not expire. They rot due to weather and use. Drive by your local trash yard and check out how fast those tires "expire".

Same as plastic. Plastic does not expire. it will deteriorate, over thousands of years but it does not go bad.

but what i am saying is that as the rubber brakes down is makes them more prone to the weather weakening them thus the "expire." And 18 wheelers do retread on everything but the fronts right?
