Can You Buy Just One Tire -

The short answer is yes, you can buy just one tire. However, while it is physically possible and often the most budget-friendly immediate choice, whether you should depends entirely on the health of your remaining tires and the type of vehicle you drive.

In summary, buying a single tire is a viable "patch" for a new set, but a risky gamble for an older one. When facing this choice, the best course of action is to have a technician measure the tread depth of your remaining tires. If the difference is too great, the upfront cost of a second tire—or even a full set—is a small price to pay compared to the long-term costs of uneven wear or mechanical failure. If you're dealing with a flat right now, tell me: What is the of your car? Is it All-Wheel Drive ? Roughly how many miles are on your current tires?
