Cals is definitely right. And the scary thing is that a tire store can sell you an expired tire and you may never know and it puts you at risk.Tires can dryout before the treads wear out. They begin to seperate or crack in between the treads or on the sidewall. This usully beings to happen around five years but can happen quicker to cheaper tires. They are made of steel belts with rubber glued to them and under go extreme temperture changes so after time they become more and more pron to giving out. Be sure to check your tires psi, wear and for deep cracking (if you can fit a ball point pen in you should replace). Tires have a born on date; the last four digits of the DOT number are the week and yeaer a tire was built. XXX XXXX XXX 0306 would be a tire built the third week of 2006. Hope this was some help.
There are no stupid questions only stupid answers. The post above are correct heres a link;Okay at the risk of sounding stupid, I ask this question.
I recently heard that tires actually have an expiration date?
That after X-amount of years even if the tread is good, the rubber is bad?
Can anyone clarify this for me please?
No, the conti's are just garbage to begin with. That's why you have only 50% left.im checking exp dates from now on before i drop 500 bucks of my hard earned money on tires. i had no idea tires had expiration dates. Maybe my conti's i got with my g6 were expired because i've had my car 6 months now and there is less than 50% tread left. Phuk dealerships they screw you over on everything except warranty replacements. Tire exp dates: one more thing to check before buying a car (other than looking at the tire and saying good enough)
yup.. now I knowHere's an informative link to tire life, manufacturing and tire dealer sales. There are no guidelines issues by the NHTSA on how to regulate tires. The manufacture date is generally stamped on the inside of the tire, so people (like you and I) ignore it instead of taking the time to check how old the tires are. New cars are generally built with tires less than one year old. Europe has age limit laws, where us poor North Americans, do not.
