Question: What is the expected life of a road tire and tube?

I am using the stock wheel set that came with my 2002 Trek 2200. I do not want to risk a blow out and am willing to spend a bit extra to keep the wheels in top shape. I ride on average roads during the season and on rollers in the winter. Any idea about how many miles / KMs a tire or tube should be replaced.

Thanks in advance.

Round and round in circles all the time. What a headache.

You might as well ask what is the life of a human being. There are far too many variables for there to be a definitive answer. Just by riding you are risking a blowout, so unless you have a museum-quality bike (which you don't), I wouldn't get too caught up in it. You will have a blowout at some point. Expect it. It won't destroy the wheel, and most likely it won't even harm the wheel.

Just ride. Replace your tires when they get worn. Replace or patch your tubes when they go flat.

Tires vary depending on use. Rear tires wear faster than front ones. For a rear tire, expect a minimum of 1,000 miles (unless you get a cut). I'd guess 2,000 is about as far as you'd expect a rear tire to go, but if you're lucky, maybe longer. If you think yours might be betting old, ask your LBS to take a look.

Make sure your best tire is in the front. If you buy a new rear tire, rotate your old front to the rear. The reason for this is that at speed a front blow out is much worse than a rear.

Tubes can last forever if you're careful and/or like to use patch kits. If the tube blows it's history, but a puncture can be fixed. A buddy of mine brags that his slime filled MTB tubes are more than 3 years old, and he has never done anything except top them off with air before riding.
A couple of factorsKerry

The primary items for tire life are rider weight and tread thickness. These two combined (light rider, thick tread) can easily result in a 5X factor difference in tire life. At 180 lbs. I get about 2000-2500 miles on a Conti GP3000, while my 125 lb. wife gets over 10K miles on a Conti GP. Then you can throw in riding style, road surface, and tread compound for another 10-20% variable. Some throw out tires well before they are truly worn out on the theory that worn tires have more flats. That's not been my experience, and I run tires until the casing threads just start to show through the tread. Obviously a cut that goes through the casing means the tire is dead. Cuts can happen to brand new tires, and are not more likely as a tire ages except from a statistical point. Unless you are riding very low mileage, you'll wear out the tire before the casing gets weak enough to worry about blowouts.

Tube life can be thought of as "years" since you can patch them repeatedly without increasing the probability of subsequent flats. Punctures that require overlapping patches, seam failures, and stem base leaks are the reasons to throw out tubes, and this may take years to occur. When you do a poor job of patching a tube, sometimes you will tear the tube when removing the old patch, and that obviously means throw away day.
Shallower cuts mean more as tread wears down.dzrider

I also look for any sign of casing threads and replace the tire immediately when I find them. If a cut produces a bump, I replace the tire. In my experience the most dangerous cuts for blowouts are on the sidewall, not the tread.

I have 4,200 miles on a pair of Michelin Axle Pros. It has a lot to do with your weight and how aggressive you ride. I have had only 1 flat in that time also.
