Mine is a '98. picked it up last Nov. and the tires looked to be in excellent condition. Plenty of tread, no sign whatsoever of any rot, they've been holding air with no issues. Got her back on the road and didn't really think about it much until I looked at them a bit closer recently.
They are both Bridgestone Exedra tires with the following codes:
front PCB1901
rear PMD277
If I remember the codes right, the front was manufactured the 19th week 2001, the rear - 27th week 1997.
I'm a bit concerned that the tires are so old but as I said, they still look to be in great shape. How worried should I be about 12 and 16 year old tires?

I agree, I would replace them. Even though you don't see any cracks, when the sidewall is flexed, they may become visible.

Just did this with a set of truck tires made in 1998. Almost new tread with no visible cracks, when the tires were flexed taking them off the wheels, the whole sidewall was covered in hairline cracks. These tires would have probably blown out at the worst possible time, in a turn at 50 mph, beside one of our many cliffs and river banks.

The old front tire on my bike looked ok, but was deformed after it was off the wheel.

I'm lovin' my new Shinko tires. Bikemaster has them on sale right now, but I got a great deal on two tires from Pinwall Cycle on Ebay. Their shop is in Massillon, Ohio.

I just replaced a set on a friends Harley ,02 model with 4k on them .While on the outside they looked perfect with little to no wear after taking them off the back one was full of rubber particles almost as big as a bb ,that had came off the inside sidewalls.

I would absolutely change them out ASAP !!

If they have a good tread on em, you can always tube em....thats what we did in the old days when a lil dryrot was showin in the sidewalls...you could get another 6k if the tread is good....

The recommendations for replacing motorcycle tires, regardless of tread depth and condition, varies by class/type of bike;

Racing: 2 years
Street Sport: 3 years
Cruisers/touring: 5 years

In fact, the local race track will not let any bike on the course with tires more than 2 years old, even if they are brand new! I'm told other race tracks have similar rules.

Also, get the newest pair of tires (check the date codes) when you purchase new tires. If they have been sitting on the shelf in the shop for 10 years, then they are no good either.

I don't go by any time or mileage recommendations for replacing tires, I go by condition. Those time recommendations are there to protect the tire companies, and to help sell new tires. I have used bike tires older than that, that had good tread and no cracks without problems. I have used 40 year old belted car tires with no problems Rubber lasts a LONG time if not exposed to sunlight. All tire companies always recommend replacing any motorcycle tire that has been punctured, even if it is brand new. I have 2 plugs in my rear ME880 right now, with maybe 10,000 miles left in it. I intend to wear it out. But it does depend on the size, type, and location of the puncture. A piece of a broken bottle of sharp metal can destroy a tire. A small nail puncture in the tread area is no cause for concern IMO. But just like the tire companies, I'm not going to advise you what to do, I don't want to be responsible for an accident. Just be aware that there are no hard and fast numbers to go by, check the tires, and make your own decision.

There is one thing that can destroy a tire, and not show any indication of a problem. That is flat spots. If the tire has been sitting with the weight of the bike on it for some time, especially if the pressure was allowed to get low, the tires are likely damaged. The belts take a "set" and stay that way. They may look round when inflated, but it is easy to find this kind of damage. If the whole bike jumps up and down while riding down the road, the tires are likely flat spotted, and ruined. The belts will eventually break and separate at the flat spots.

It's always good to know what your life's riding on. Old tires can be a hazard but, it like Jerry said, you have to decide what your comfortable with. The front tire on mine had good tread but had dry cracks in it when I bought it. I rode on it till it was wore out, with no problems. I have since replaced both tires with shinkos. All told I was out 140-150 bucks for new rubber and I did all the work my self. My bike is my primary so it pays to keep up her up to speck. A flat when u gotta go to work is no fun.

I took a chance becouase I couldn't afford new rubber at the time. If your ever in the same boat u know u do what u gotta. Wolfe is on to something though. If the treads good but your doubtful about the sidewalls it would be cheaper to tube it yourself and get the use out of it than just replace the tire. I hadn't thought of it at the time or that's what I would have done.

I anticipate wearing out the tread on my new tires befor I have issues with age but like I said I ride pretty much daily. Most bikes don't see the miles I put on mine so a set of tires may last years for the weekend rider. I say if you have the jack then take the high road and wrap some new rubber one the rims, if not then yea tube it and get the use out of thoese bad boys:) just my 2 cent
