If a tire is wearing in the middle but has good tread, what could be the issue with the tire?

When a tire shows wear in the middle but maintains good tread depth, it is often a sign that the tire is over-inflated. Over-inflation causes the center of the tire to make more contact with the road than the edges, leading to uneven wear patterns. This can happen when a tire is inflated beyond the manufacturer's recommended pressure, causing the tire to bulge in the center and reducing the contact area with the road.

Maintaining the correct tire pressure is crucial for optimal performance and safety, as it affects handling, braking, and fuel efficiency. It's important to regularly check tire pressures and adjust them according to the vehicle manufacturer's specifications to prevent such premature wear and ensure a safe driving experience.
