How do you know when you need new tires?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

How do you know when you need new tires?

Is it just based on mileage? Are there some visible signs of wear to look out for? Wait until it blows out at 35mph?

I bought my bike used and Im fairly sure the front tire is original. The guy claimed he only put 1800 miles on the bike, but I have no way of confirming.

1800 miles on a front tire isn't bad. I usually get 1500 on the rear and replace the front with the third rear change. So that's 4500 miles.

Some tires like Conti put wear indicators on the rubber (Conti uses two little holes). Just keep an eye on the wear and don't let the thread material show. Also if you flat often, that's a potential sign to change.

Some tires have wear indicators - it's generally a little bubble in the tread that when it is gone, you need a new tire.

Other key indicators are
* Dry Rot - tire starts looking cracked.
* Squaring - The tire become flat along the main edge and it starts to look square instead of round.
* Thread casing - you can see the thread casing because the tread is so worn.

I have found that tires last anywhere from 1,000 to 3,000 miles depending on use and brand.

^What he said. If your tires have wear indicators that's usually the best way to tell. If not look for any squaring off in the tire or cracks. I have about 2700 miles on my current set of tires, both front and rear and the rear needs replacing pretty soon. Rear usually wears faster than the front.

I disagree. I often run a tire down to the cords without getting any flats. I replace the tire when the rubber wears down thin enough that I can see the casing through it.

This. Threads are the wear indicators.

i replace my tires when: they get over 4000 miles, 30 flats total, or too many nicks, tears, or the tube is sticking out of the tires.
