Coming to you from A & R Tire, talking about how to buy tires. Buying tires, as far as how often you should do that, that really depends on how many miles you drive per year and what kind of driving conditions you are doing. Typically, a tire today is going to run--last you about 50,000 to 60,000 miles is probably a good average. Other conditions is the casing; it deteriorates after about five years. So we always recommend that the date coat on the tire, the last four digits, are five years old. We always recommend replacing that for safety issues. The tires, basically, has seen its useful life, and it's more likely in our Southern California market that tire will probably and more likely will [SOUNDS LIKE] dry rot. So we always recommend five years, but we also look at the tread. If it's 2/32 or less, it is time to replace that tire. On most of your vehicles today, on your light-truck tires, as far as the spare goes, on your light-truck tires, it's usually a full-size tire, the same tire that came with the other set of four. So yeah, those tires are good for 40,000, 50,000, 60,000 miles. You should also do a five-tire rotations, keep a fresh spare under there at all times, and you'll get a little bit more wear. You're going to get another 20-30% of life out of your set of tires. When you, of course, when you have a space saver, that tire is going to run, get you about, providing the vehicle's properly aligned and you drive it 50 miles an hour, that vehicle--that tire is going to get you approximately 5,000 miles.
