should i start to worry/think about a new one?

I was inspecting my bike today looking at what I want to fix...

I found this...


a small crack in the tire tread... should i worry? or jsut keep it at the right pressure and keep driving while paying close attention?

Somewhere I read that general rule is replace tires after two years. Don't know snce I've always worn tires out before that.
Extreme heat, cold etc start breaking down the tire and you start seeing cracks in the sidewall etc.
You didn't say how many miles or how long the tires have been on the bike but with just the small crack (good inspection by the way!) if you have ride-on in the tires you might be ok.
Keep an eye on them and if you see more developing then start shopping.
I noticed you are in Michigan and winter storage may have contributed to the small crack

just bought the bike... stock tires and it is 8 years old and 3,100 miles... the rear tire is really good. I will scan prices though.

Well Duh! *L* I should have figured out the age of the bike by your name huh!
But, given the fact that they are also 8 year old tires then yeah you probably do need to start thinking about replacements.
Actually they look pretty good with only the one crack. I'd give the sidewalls a real good check too since that is where the age stress seems to show up more.

Found this about sidewalls, it mentions Ford but gives a pretty general rule to go by
Over time, rubber degrades. Ford has recommended that tires be replaced when they are 6 years old to prevent sudden failure, even if the tire looks undamaged. In tropical climates, such as in Singapore, tires degrade sooner than in temperate climates. Tires on seldom-used trailers are at the greatest risk of age-failure but some tires are built to withstand idleness. This is usually done by using nylon reinforcement. In the past rayon was used in tires but it ages quite badly.

I bought a 2003 last August with 4,300 miles. I just dropped it off at the shop at exactly 7000 miles for new tires. The tires look fine tread wise, but have some dry rot on the sidewalls. Not a lot, but enough to bother me, especially being a new rider. I had read tires should be replaced every 5 years regardless of mileage and figure $300 is not a lot compared to my life.

I would atleast start looking for tires, and plan on replacing soon, seeing as you believe they are stock (you mean as in original?) tires.
With only having two of them under ya, if one goes, there could be trouble. Be careful if you shop the internet as many will sell tires cheap because they are old stock.

Replace both tires now... Stock tires are usually not the greatest but rather what the manufacturer could get in volume for cheap and with them being the original 8 year old skins, you are asking for a catastrophic blowout any day.

Please don't trust those tires. What you might not be seeing is the rot under the surface...
