What distinguishes radial tyres from other tyre types?

Radial tyres feature plies running perpendicular to the tread and are reinforced by steel belts under the tread. This allows the sidewall and tread to operate somewhat independently, enhancing flexibility and road contact compared to older bias-ply designs.

What are the primary benefits of using radial tyres on passenger cars?

Radial tyres offer improved fuel efficiency, better grip, enhanced ride comfort, longer tread life, and superior handling due to their flexible sidewalls and stable tread design, making them the standard for modern passenger vehicles.

How often should I check the pressure in my passenger car radial tyres?

Tyre pressure should be checked at least once a month and before long trips, preferably when the tyres are cold. Correct pressure is crucial for safety, fuel efficiency, and tyre longevity.

What do the numbers and letters on a radial tyre sidewall signify (e.g., 205/55 R16)?

The numbers indicate the tyre's width in millimeters (205), the aspect ratio (sidewall height as a percentage of width, 55), 'R' denotes radial construction, and the final number is the rim diameter in inches (16).
