When replacing a single tire, where should the new tire be placed?

Placing a new tire on the rear axle is the recommended practice to ensure optimal vehicle handling and stability. When a new tire is installed on the rear axle, especially alongside a tire that has deeper tread, it enhances traction and reduces the likelihood of oversteer. This is particularly important in conditions where road surfaces are wet or slippery, as worn tires on the rear can lead to a loss of control.

The rationale for this approach is based on how vehicles handle during cornering and braking maneuvers. If the rear tires lose traction while the front tires maintain grip, this imbalance can cause the vehicle to spin out, posing a safety risk. By ensuring that the rear maintains the best possible grip with newer, deeper-tread tires, drivers can sustain better control and reduce the chances of losing stability.

This practice contrasts with the idea of placing a new tire on the front or on either axle arbitrarily, which does not adequately address concerns regarding vehicle dynamics and safety. Prioritizing the rear axle when replacing a tire ensures a balance in handling and safety.
