Yes, improper use of a tyre inflator can potentially damage tyres. The most common issues include:
- Overinflation: Exceeding the manufacturer's recommended pressure can cause the center of the tread to bulge, leading to uneven wear, reduced traction, and increased risk of blowouts at high speeds or in hot conditions.
- Underinflation: Insufficient pressure causes the sidewalls to flex excessively, generating heat that can lead to tyre failure. It also reduces fuel efficiency and accelerates tread wear on the outer edges.
- Uneven Inflation: Inconsistent pressure across all tyres can cause handling problems, uneven wear, and stress on suspension components.
Prevention Tip: Always check your vehicle's recommended tyre pressure (found in the owner's manual or driver's door jamb) and use a quality inflator with an accurate gauge. For maximum safety, verify the pressure with a separate gauge after inflation.
