How must vehicle tires be arranged in relation to each axle?

Tires play a critical role in a vehicle's safety and performance, and having them properly arranged is vital for maintaining proper handling, traction, and stability. For each axle on a vehicle, the tires must be the same size; this helps ensure even distribution of weight and balanced performance. When tires of the same size are used on each axle, it promotes uniformity in how the vehicle responds to steering inputs and maintains consistent grip on the road.

Consistency in tire size across an axle prevents potential friction or wear discrepancies that could arise from using different sizes, which might compromise the vehicle's handling and increase the risk of tire failure. Additionally, having tires of the same size helps avoid issues with the vehicle's transmission, as differing tire sizes can affect the vehicle's overall dynamics.

Varying tread depth or using tires of different models can lead to inconsistent performance and may violate safety regulations, which is why adherence to the guideline of uniform size per axle is essential in vehicle inspections. This ensures that the vehicle adheres to safety protocols and functions efficiently on the road.
