Front

If a tire is overinflated, which part of the tire wears out first?

Back

inside part of tire

Answer explanation

When a tire is overinflated, the pressure causes the center of the tire to bulge, leading to increased wear on the inside part of the tire. This results in uneven tire wear, primarily affecting the inner edges.

If a tire is underinflated, which part of the tire will wear out first?

Back

outer part of tire

Answer explanation

When a tire is underinflated, the outer edges of the tire make more contact with the road, leading to increased wear on the outer part. This is why the outer part of the tire will wear out first.
