8 year old tire question
Hey guys my 2005 Roadking Classic has 15,000 miles on it and the tires still have 4/32 rear and 5/32 front tread depth on the original tires. They are showing some signs of light cracking between the treads. I heard over the weekend they should be changed every 2 years regardless of the tread depth. What do you guys think?
Industry says 4-5 years from date of manufacture is tire life. Irregardless of tread depth. Depending upon condition, they might be okay up to 10 years. But most manufacturers say 10 is the max.

I work for Bridgestone Firestone corp
The tire manufacture states that a tire become unserviceable at 6 years or 2/32 tread ware.
After 10 years the tire become unstable at speeds and can come apart as the tire heats up from driving.

Yes. Tires have a shelf life.
On the side of every tire sold in the us is a set of numbers. Dot numbers. 8 to 12 digits in length. The last 4 numbers is the week and year the tire was produced and is timed from that point on.
A tire with the numbers xxx-xxx-0208. Represents a tire that was produced and put in service in the 2nd week of the year 2008 it is the birth date of the tire. At6 years it should be taken out of service no matter how good the tread is and at 10 the tire can no longer be serviced by a dealer legally that is.

There are various 'rules of thumb' about tyre life, and cda1277's 6 years falls in the middle. I recommend you fit a new pair as a matter of some urgency! You will probably find the bike rides much smoother, in lovely new rubber cushions, and handles more sweetly too.
