Radial vs Bias

The differences between Bias and Radial technologies

The radial tire revolutionized the world of tires when invented in 1946 and put Michelin well ahead of the competition. Over the years, Michelin has maintained the leading position in terms of spectacular research and innovation.

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




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

A bias tire consists of multiple rubber plies over lapping each other. The crown and sidewalls are interdependent.

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

The advantages of Radial technology over Bias technology



Sidewall flex is not transmitted to the tread. The footprint only lengthens. There is little transversal slip (What?). The radial tire allows the machine to transfer more power to the ground.

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

Choosing Radial tires for your activity

  • Lower fuel consumption.
  • Less ground compaction and damage.
  • Greater productivity. More of your machines power is actually used.
  • Reduction in tire replacement thanks to the longer service life of radial tires.



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

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

Choosing Radial tires for your farm

  • Greater comfort for users.
  • Reduced machine maintenance costs.
  • Less Compaction
  • Better Traction
  • High Crop Yields and more profit
