Radial or Bias, the right choice

Invented by Michelin in 1946 the radial tyre, with its locking ring, revolutionised the world of agricultural tyres and put MICHELIN® well ahead of the competition. Over the years, the new, original solutions that have been brought out have confirmed Michelin’s leading position in terms of spectacular research and innovation. 

The difference between Bias and Radial technology

The radial tyre, invented by Michelin in 1946 revolutionised the world of tyres and put Michelin® well ahead of the competition. Over the years, Michelin has maintained a leading position in terms of spectacular research and innovation.

Today, a full range of new products has been developed in conjunction with major agricultural machine manufacturers in response to the continuous evolution of farming techniques.

RADIAL TYRE

BIAS TYRE

Advantages of the radial tyre over the bias tyre: reduced soil compaction, improved traction in all conditions, increased durability and productivity.
Advantages of the radial tyre over the bias tyre: reduced soil compaction, improved traction in all conditions, increased durability and productivity.

A radial tyre allows the sidewall and the tread to function as two independent features of the tyre.

A bias tyre consists of multiple rubber plies overlapping each other. The crown and sidewalls are interdependent.

The overlapped plies form a thick layer that is less flexible and more sensitive to overheating.

Tha advantages of Radial technology over Bias technology

Bias tyre

Sidewall flex is not transmitted to the tread of the agricultural tyre tread. The footprint only lengthens. There is little wheel slip. The radial tyre allows the machine farming equipment to transfer more power to the ground.

All sidewall flex is transmitted to the tread. The footprint deforms and there is an increase in tyre slip.
 The tyre does not contact as much ground as a radial tractor tyre, leading to a loss of engine power transmission and greater ground damage.   

Choosing Radial tyres for your activity

  • Lower fuel consumption=greater fuel savings when using your agricultural machinery
  • Less ground compaction and damage.
  • Substantial improvements in a farm’s productivity and profitability. Greater productivity. More of your machine's tractor's power is actually used.
  • Reduction in agricultural tyre replacement thanks to the longer service life of radial tyres.

BiaThanks to the flexibility and strength of the tyre, the tyre absorbs shocks, impact and bumps.  The result is a better ride and better operator comfort.

Due to the stiffness of the tyre, it does not absorb bumps on the ground. All impact and shaking  is felt by the driver and machine.   

Choosing Radial tyres for your farm

  • Greater comfort for users.
  • Reduced machine maintenance costs.
  • Less Compaction of your soil.
  • Better Traction of the tractor wheel.
  • Higher crop yields and more profit potential for your farm.
