Tires are arguably the most important safety feature on any vehicle. They are the only part of the vehicle that makes contact with the ground and their grip is of paramount importance. Tires are also the part most likely to need replacing over the life span of a vehicle. In fact, the only part of a car, truck or sport utility vehicle guaranteed to wear out are the tires. So it is kind of surprising how little most people know about tires. When shopping for new tires, most people simply take the advice of the sales person they are speaking with and go with the tire that is recommended for their make and model of vehicle. Yet this is not always the best approach. Sales people, after all, are often pushing to unwind inventory or unload certain tires that are not selling well. Knowing some information about tires—even basic information—can help ensure that you get a good deal on the most suitable tires for your vehicle. Here are eight tips to keep in mind when buying tires.
8. Know the Size of the Tires You Need
This might sound painfully obvious, but ask most people on the street what size tires are on their car and they’ll look into space and blink a few times. Most people have no idea what size tires are on their vehicle. And it is for this reason that incorrect tire size is one of the biggest problems that occur when it comes time to replace tires on a vehicle. Fortunately, the tire size is readily available. People just have to look. And you can find the correct size on the sidewall of your tires. The tire size and its capabilities will be right there. Jot it down on a piece of paper before you go to the garage or tire dealership and make sure the new tires you buy are the exact same specifications.
