Q. I have a 2006 Jeep with a full-size spare tire I’ve never used. I plan on keeping this Jeep as long as possible, and now it’s time for another set of tires. Can I use the spare and buy three new ones?

A. The tire industry trade group RMA doesn’t look at age as much as overall condition of the tires. Other experts recommend replacing tires that are six to 10 years old, just to be safe. With a four-wheel-drive vehicle like your Jeep, it’s important the tires all match. Since the spare tire was exposed to a variety of weather conditions, and tread designs can change over time, I would purchase four new tires and keep the spare where it is.
