My friend has a new dunlop that has been sitting in his garage for over 2 years. Any problems with using a tire that has been sitting that long??
Thanks

 

The front one on my bike is over 2 years old.

If there hasn't been anything laying on it to squash it, or chemicals spilled on it, or mice chewing on it, and it doesn't look bad...I'd ride it.

 

The tires on my Kawasaki H1 are 36 years old. I go over 80MPH frequently with them. I'm not saying that I know that nothing is wrong with them, in fact it might just mean that I am crazy. When I inspect them I don't see any bulges or cracks and they don't wobble like a tire with a broken bead so I have just stuck with them.

 

YIKES! Change 'em man, before you get killed!

There is a date code on the tires, have him check it (I'd have to get up to tell you exactly where it is, and I ain't getting up right now!) and see how old they really are. Anything beyond 6 or 7 years is suspect.

 

I wouldnt use them. the interior of the tire has been exposed to the elements and who knows what else. Rubber rots. Why take a chance? Is money that tight?

 

I'd use it, 2 years isn't that long.

 

Probably OK, but there are some ifs: If it has been stored next to an area where electric motors run much or has been stored next to some electric switchgear/panels then the ozone that those things generate would have done some damage to rubber content. No joke!... it is very real. Also, if it was bathed in sunlight every day then that is a deteriorator too. Visually look for tiny cracks. Every day of its life some of a tire's chemicals cook/harden/evaporate.

 

Who's to say it didn't sit in a warehouse another 2 or 3 years before they got to your buddys garage. Being stored in a garage humidity and temp changes also affect the rubber. May look good now but when you start running them, they may break down fast.

 

worst thing IMO would be chemicals and direct full time sunlight contamination.
a lot of tires even sit in stores for two yrs.
I know car tires have date codes in them, not sure MC do but I would think so. as stated above 6-7 yrs regardless of miles on them then there out of here....

 

I'd say bend the tire back and forth . lookin for weather cracks , chemical burns , or just plain rot . If it's not present ..............good tire .........Kev
