What happens if a vehicle has two or more tires of different sizes on the same axle?

Having two or more tires of different sizes on the same axle results in a failure of the inspection. Uniform tire size is critical for safe vehicle operation, particularly regarding handling, steering, and braking. Tires of varying sizes on the same axle can cause uneven wear, instability, and may affect the vehicle's overall performance and safety. This inconsistency can lead to complications in traction management and control, especially during emergency maneuvers or adverse weather conditions.

This requirement is in place to ensure that vehicles are equipped for safety and efficiency on the road. It helps prevent potential hazards that could arise from mismatched tires, making it a key aspect of the inspection process.
