I noticed today my rear Shinko is almost down to the wear bars so it's not going to get me through the rest of this riding season.

I've got a "new" Kenda 761 I got a deal on a couple of years ago sitting in the basement and was thinking about just putting it on for the rest of the year. It's a tad "street-oriented" for me, but it should get me around where I need to go as long as I remember it's back there.

It's never been used or mounted and has been kept in my climate-controlled and dry basement for the past couple of years. It still looks and feels like new.

I've tried to give it away on here a couple of times and had relegated it to kind of a backup emergency rear, always opting for another Shinko 244 rear instead of mounting the Kenda.

I don't see any reason it wouldn't be safe to use. Anybody think it would be unsafe?

I think I "read somewhere" you shouldn't use a tire that's been sitting around for a couple of years, but that seems kind of far-fetched to me. I could see that reasoning if the thing had been exposed to wide swings in temperature, humidity, etc. but this one hasn't.

If I don't use it now, I'll probably just wind up throwing it in the trash because I'm getting tired of looking at it.

I really can't imagine there aren't tires in any given motorcycle shop that haven't been sitting back in the warehouse racks for a couple of years before somebody wants them and they put them on, but maybe I'm wrong.

Edit: Found this date stamp on the tire that shows it was made in the 31st week of 2011 so the tire is basically 3 years old. I would project that it will most likely stay mounted on my KLR until next Spring, so say 5-6 months of riding, maybe 2000-3000 miles tops since I don't commute regularly any more; mostly just joyriding. For the record, the little specks on the tire are sawdust. Even though it was still enshrouded in its original plastic shipping wrap, it's been sitting right behind my chop saw for all this time.

I wouldn't hesitate to use it.
That's what I'm thinking, stew. The following is an excerpt I found on the web site of an unnamed motorcycle dealer. I see their point: it would be possible to buy a set of "new" tires online that are already 10 years old, but it seems to me like they're just trying to use scare tactics get people to buy tires from them instead of finding better deals online:

"So, the “new” tires you just bought online last month for your bike could actually have already been a couple of years old and well into the disintegration process before you bought them. The tread can even look perfectly fine as if it just rolled off the assembly line, but the structural integrity can be weakened and possibly deadly. Then, the dried out rubber being susceptible to the elements, can start to visually dry rot on the outside. There’s no rhyme or reason to how long it takes a tire from here to actually become ‘unsafe’, but who wants to find out? No thanks."

2 years old and "well into the distentegration process?" I just don't buy that. But, as noted before, where and how they were stored could play a large role in that.

I've been wrong before, though, so thought I'd throw this out there for opinions.

As a side note: "never leave a battery sitting on a concrete floor." I've heard this one for years but it never made any sense to me.

I think I have had my tires on my bike for at least 6 years. It has seen extremes in temperatures (I lived in both Northern Canada and Perth Australia) other than normal wear, the tires are fine.
To me it sounds like a dealer trying to flog his own products and using fear mongering to do it. I'm sure your stored tire is fine. You would be crazy to toss it in favour of a new one. IMHO

Well, two opinions are good enough for me. The Shinko's technically not dead, but it's close enough. The Kenda will be going on this weekend.

Unless signs of deterioration (e.g., "dry rot") appear, I'd imagine the tire is safe, ESPECIALLY a tube-type tire.

Why the distinction between tubed and tubeless? A tubed tire does not depend upon the casing for air-tight integrity. A serviceable inner tube helps insure an aging tire holds air.

The 761 seems to get pretty good reviews except for traction on wet pavement. I intended to put it into a rotation of experimental tires but never did after being quite happy with the Shinko 244.

Agree with all of the above. Sounds like it was not exposed to any bad weather and the manufacture date puts it in the safe range. A dealership would sell it.

I just replaced my 761s with another set of 761s and in my trip last summer I ran 4 hours in rain that was pouring sideways and they handled perfectly, no slippage. I, on the other-hand, just need a bar of soap to complete that shower...
