Why Buy Four Tires?


Why Buy Four Tires?

When you are in need of a tire replacement, we recommend replacing all four tires at the same time. When the construction, tread design, tread depth and tire type of all four tires on your vehicle match, the reaction of your tires to road conditions and driving stress will be completely uniform. An identical reaction from all four tires improves your vehicle’s safety, balance, stability and overall handling.

Ideally, with proper tire rotation and regular maintenance, all four tires should wear evenly requiring replacement at the same time. However, if you do not rotate your tires regularly on a front wheel drive vehicle, it is common for the front two tires to wear out faster than the rear. While it is best to replace all four at the same time, in situations where this is not an option, consider the guidelines below.

Replacing all four tires at one time is ideal

Replacing Less than Four Tires

  • Be sure to match the size, construction and tire type of the older tires as closely as possible.
  • If you are not in the market for four tires, we recommend purchasing no less than two.
  • The two new tires should always be installed on the rear axle of any vehicle. If you are only replacing one tire, select the older tire with the deepest tread and install it along with the new tire on the rear axle.

Why must the new tires always be installed on the rear?

The deeper grooves in the tread of the new tires effectively evacuate water away from the tire’s surface, creating better traction and greater hydroplaning resistance on wet roads. Creating greater traction on the rear axle allows you to steer the vehicle to compensate for the lower wet traction of the front tires and safely maintain control. When new tires are mounted on the front axle, the worn rear tires have less tread and lower hydroplaning resistance. They can lose their grip on wet roads, causing the rear end of the vehicle to swing around out of control.

Note: In some cases, the vehicle manufacturer may specifically advise against replacing less than all four tires. Always check and follow the recommendations in your vehicle’s owner’s manual. For all-wheel drive (AWD) vehicles, even small differences in outside diameter may cause drive-train damage or mechanical malfunction.
