Question: 1 / 400

During a pre-trip inspection, which statement about tires is true?

Tires of different sizes can be used together

All tires should be matched by brand

Tires of mismatched sizes should not be used on the same vehicle

Tires of mismatched sizes should not be used on the same vehicle because they can lead to uneven handling, increased wear, and potentially dangerous driving conditions. When tires are of different sizes, they may have different grip levels and performance characteristics, which can cause the vehicle to track unevenly. This can affect steering precision and stability, especially during turns or when sudden maneuvers are necessary.

Ensuring all tires are of the same size promotes uniformity in handling and traction, contributing to safer driving and better vehicle performance. Matching tires helps maintain a balanced center of gravity and ensures optimal contact with the road surface, which is critical for both safety and tire longevity.
