Almost every car on the road has a spare tire, but do you know how to use it? Better yet, do you even know where it is? It seems that many people don’t even realize they have one, and we’ve seen spare tires in 15-year-old vehicles that have never seen the light of day. Chances are you, too, may never need to use one, but it’s a good thing to know. After all, you never know if you might wake up to a flat tire in your driveway or have the TPMS (tire pressure monitoring system) give you a warning out on the highway.
If you think about it, a tire is basically a balloon, albeit a very serious balloon. Made of steel and fabric bands encased in rubber, your tires give you traction, control, and a measure of shock absorption. Still, as a balloon, it can be deflated. Road debris, such as stray car parts or sharp rocks, can puncture the tire. The tire may leak from the valve stem or between the tire and the wheel. In some cases, wheel damage, such as a bent or cracked rim, can allow air to leak from the tire.
The result is a flat tire, and they can happen to everyone. It doesn’t matter who you are, what vehicle you drive, or even how you drive it. Still, everything you need to know is right there in your owner’s manual, which you should get to know intimately. If you don’t have your owner’s manual, you can buy one from your dealer or Amazon or eBay. You might be able to download it for free at JustGiveMeTheDamnManual.com. In case you get a flat tire, here’s what you need to know.
There are three kinds of spare tire, depending on the vehicle. If your vehicle is equipped with a full-size spare, then it works the same as the tires already mounted on your vehicle. If your vehicle has alloy wheels, the spare may be mounted on an alloy wheel or a steel wheel, and different lug nuts may be required.
The temporary spare or compact spare, sometimes referred to as a “donut,” is narrower than the tires mounted on your vehicle and may be of a smaller diameter. As its designation suggests, it is for temporary use only, for a limited distance and maximum speed.
Vehicles equipped with run-flat tires are usually not shipped with a spare tire, and may not even include a space for one. Instead, run-flat tires are built with extra-strong sidewall materials. If a run-flat tire goes flat, you can still drive it but, like temporary spare tires, for a limited distance and speed.
While you can use a full-size spare under all the same conditions, speeds, and distances of the regular tires, use caution when driving with a temporary spare or run-flat tire. The temporary spare and run-flat tire are only meant to be used for a limited distance and speed. Exceed that distance or speed and you could ruin the tire, your car, or lose traction and get into an accident. Replace a temporary spare or run-flat tire as soon as possible.
Once you discover you have a flat tire, you’ll have to replace it with the spare tire. It’s a good idea to practice this on a nice day if you can. Full instructions for your specific vehicle can be found in your owner’s manual, but here are the basic steps you need to follow.
