Bias & Radial

Bias construction

The crown and sidewall are formed by the same ply structure.

The tread is subjected to any flexing which occurs and this causes :

  • deformation of the tyre contact area on the ground
  • friction with the ground

The casing plies tend to “scissor” in relation to each other.

As a result, there is :

  • Accelerated wear
  • Poor grip
  • High fuel consumption
  • Fair road holding
  • High heat built up
  • Prone to crown punctures

Radial construction

The sidewall and tread areas function separately.

The tread is unaffected by the flexing of the sidewalls, so there is :

  • less deformation of the tyre contact area on the ground
  • less friction with the ground

There is no movement between casing plies.

Advantages :

  • Longer tyre life
  • Excellent grip
  • Reduced braking distances
  • Even ground pressure over the whole contact area. This provides excellent flotation.
  • Lower fuel consumption
  • Smoother and better road holding
  • Cool running : giving added safety
  • Excellent protection against punctures
