For how many miles will an average set of tires last?

There are a lot of variable in determining the life of a tire. Speeds driven, tire rotations, air pressure, distances driven, how one accelerates from a stop, how sharp one turns, weather, type of tire, weight of vehicle, payload of vehicle, and other similar factors all affect the life of a tire. Unfortunately, it's difficult to give a general estimate; however, some vehicles can fall between 15,000 and 30,000 miles.

The average is not really meaningful. Tires sold in the USA (and maybe most other places in the world) now have a tread-life rating on them to give you an idea how long they should last relative to other tires under the same circumstances. Very high performance tires with very soft tread compound may have ratings below 140. Very high milage passenger tires have ratings around 600 if I remember right. My impression (based only on my own experiences) is that a tire will last around 100 miles times the rating. If you commute on a freeway with few hard corners or jackrabbit starts and stops I (just me) think I would expect about 40,000 miles out of a 400 rated passenger tire. If you always slide to a stop and peel out at intersections, divide by 10. Maybe 20... hmmmm 50? On another note, tires also carry a traction rating (A,B,C). I would be very hesitant to buy a tire with less than an A traction rating. I certainly would not trad an A rating for a C rating, even for twice the treadwear.

I'd say 35,000 to 50,000 is about average.

It depends on the type of tires you purchase. Tires purchased new today will typically have an estimated tread life of anywhere from 35,000 to 70,000 miles though 50-60,000 seem to be pretty common ratings these days. How long they last in the real world will depend on your climate, your driving style, and what kind of tires they are. Tires engineered for high traction might wear faster than less expensive, but less grippy tires, for example.
