This may help you make a decision on running or tossing those outdated tires you may have laying around.
I have had a Dunlop 208 GP 180/55/17 tire with a date of manufacture being 2001 stored in a cool dark place for years. I finally decided to toss it out since it is now 11 years young. But then, I changed my mind and thought WTH, I'll mount that puppy up on my gixxer and see how it works. Well, I took it out for the first time today for some much needed wheelie practice.
I pulled out of my neighborhood onto the main road (About three blocks) and wacked the throttle. That puppy lit up like it was greased. I thought to myself, this could be a very interesting day. Then after a quarter mile I did a repeat and this time the front tire lifted skyward with no issues. I spent all afternoon with my friend GregBob playing on the rear tire and not once did it ever slip again. Maybe it broke loose the first time because it was cold or maybe had a little mold release on the tread. After all, it was made over a decade ago.
By days end I had lots of confidence that a properly stored tire will remain useable and perform quite well for a very long time. While I'm not sure every tire will hold it's useful life this long but this particular dunlop did. I would have no issues with dragging my knee in every corner on this tire once it's warmed up a bit. It's still too cold here to get excited about spanking a tire. However, I will pick up the pace on this old dog once the summer sun warms the asphalt and I'll let you guys know if the grip becomes an issue.
I'm not recommending anyone run decade old tires but this info may be good to file away in your memory bank for possible future reference!
