Did You Know? The Best-on-Back Tire Rule
The “Best on Back Tire Rule”
In this episode of the Did You Know? series, we explore an important tire safety principle known as the “Best on Back” rule. Many drivers assume the newest or best tires should go on the front of the vehicle, especially if the car is front‑wheel drive. However, safety experts and tire manufacturers recommend placing the tires with the best tread on the rear axle.
Why the Best Tires Should Go on the Back
The reason behind the Best on Back rule is vehicle stability.
When the rear tires have less traction than the front tires, a vehicle can lose rear grip in wet or slippery conditions. When that happens, the back of the vehicle may begin to slide sideways — a situation commonly known as fishtailing. Once the rear tires lose traction, drivers often have very little time to regain control.
Placing the tires with the best tread on the rear axle helps maintain stability and control during rain, snow, or emergency maneuvers. While the rule may seem counterintuitive, it is based on vehicle dynamics and safety testing showing that rear‑axle traction is critical for maintaining control.
Real‑World Investigation Insight
This rule also illustrates an important lesson about accident investigation.
In one catastrophic injury case, a young driver lost control of a vehicle on a lightly rain‑covered roadway. The vehicle fishtailed and struck a fence post, resulting in a severe brain injury.
At first glance, the crash appeared to be a straightforward single‑vehicle accident that many people would attribute to driver error. However, deeper investigation revealed that not all four tires had been replaced together and the Best on Back rule had not been followed.
The tires with the better tread depth had been placed on the front axle rather than the rear. Because investigators understood the safety rule governing tire placement, they knew what to examine when evaluating the cause of the crash. That investigation revealed a contributing factor that might otherwise have been overlooked.
Key Takeaway
Small safety rules can have significant real‑world consequences. Understanding those rules — and investigating whether they were followed — can help explain how an accident occurred and whether additional contributing factors were involved.
Frequently Asked Questions
Why should the best tires go on the back of a vehicle?
Placing the tires with the best tread on the rear axle helps maintain stability. If the rear tires lose traction before the front tires, the vehicle can fishtail or spin, making it much harder for the driver to maintain control.
What causes a vehicle to fishtail on wet roads?
Fishtailing often occurs when the rear tires lose traction before the front tires. When the rear of the vehicle begins to slide sideways, the driver may have difficulty correcting the motion quickly enough to avoid a spin or crash.
Do tire replacement decisions really affect vehicle safety?
Yes. Tire tread depth, tire placement, and maintenance significantly affect vehicle stability, especially in wet conditions. Improper tire placement can increase the risk of losing control.
Why is investigation important in single‑vehicle accidents?
Single‑vehicle crashes are often assumed to be caused solely by driver error. Careful investigation can reveal other contributing factors such as vehicle maintenance issues, safety practices, roadway conditions, or equipment configuration.

This helps prevent fishtailing and loss of control, especially in wet or slippery conditions. Fritz and Bianculli has handled cases where this rule was not followed, and crashes caused loss of control and serious, even catastrophic injuries.
