Well you must have not been driving too much. lol Anyway, if you look at a tires thread, they have between the threads what you call a tire wear mark. You will see a raised ridge of rubber perpendicular to the two threads. If the tire thread wears down to this then the tire is no good.
In theory, you change them when the thread seems to get low. Hard to explain though. Here is a URL to explain about tires and should answer all your questions.

Now the next thing is where to buy them. Well if there is a Discount Tire or NTW store or some other tire place check with these stores. Reason is most tire places will price match. Remember to check with at least 3 tire places. The trick is that at Discount Tire if your tire blows out and you need a new one, you just pay for the warranty on the new one. The other places will pro-rate your tire. So if you pay $70 for a 70,000 mile tire and it blows out after 20,000 miles then you have to pay like $20 extra to get the same tire again. It might be even more at some places. Check with the tire places and ask AHEAD of time on what there replacement policy is. If the tire blows out how much would it cost to get a new one? If the tire brand is not available will you match it. (Montgomery Ward would not match my tire. I would have had to pay like $60 more to get another tire and Discount Tire will get you another tire to match and there is NO extra charge, even if it is a better brand of tire)
The brand at Discount are the same as Sears except cheaper at times. When to buy tires is like on a Monday. Sunday papers usually have the sales on, and you can use this when you go to Discount or another place.

It is not so much the miles as it is the wear of the tires. If you stop by a tire shop they have a guage they can put in the groove of your tire and it will measure the amount of tire tread left. I think for North Carolina a tire has to have 1/8 inch groove to pass state inspection. The less groove you have the more likely your car will hydroplane or slide out of control in the rain. It helps to have your tires rotated every 5000 miles you drive your car. This makes them wear more evenly.

i agreed with knox about 30,000 miles is the average. it also depend how the person drive the car. if the wheel is out of alignment, it worn out fast! and have to replace it.
if your tire is back in 2002, you have to replace it too beacuse, tire also has an expire date. usually about 2 -3 year after it manufacture date. if the tires its more than 3 year, what happen is, the tire rubber is hard and it wont get proper grip for your car.
go change your tires.

Here are my thoughts on your question:
I'd ask how comfortable you feel with your tires? How is the traction and handling? That is the most important question because if you have a tire that has a lot of tread but the traction and handling is poor...well then you'd replace it.
However, with the mileage you have on them I would start shopping around so that you will have an idea of what a new set will cost you.

If you are driving a race car, about a hundred miles or less. If you are driving Miss Daisy, twenty miles a day at five miles an hour - never. It all depends on tread wear. Which depends on road conditions, speed, tire pressure and so on.

You didn't say how many miles you've put on your car...-But after 5 years, I'd say it was a pretty safe bet you probably need new tires now... Go to your local car repair place (any one will do), & get their opinion. If they don't say that you need new tires by yesterday- I'll be surprised. Take their advice & be safe. :)
