The Anti-Static Strip

A unique feature necessary in a tyre

Bias

•The carcass of a Bias tyre consists of 2 or more

diagonally orientated carcass plies. The overlap angle of

these plies can be changed to give dif fering properties

to the f inished tyre. The structure is uniform, and the

tyre crown area has similar properties to the sidewalls,

because of this, load bearing is very good.

Bias Belted

Bias structure which is belted at the top by means of a

band formed by one or two layers of crossed plies

Radial

One of Michelins most famous inventions the MICHELIN

RadialX technology with 90 casing plies on the tyre

provides grip and stability and comfort

•A vehicle is charged with static electricity and must be

able to discharge this electricity into the ground. Since the

tyre is the only point of contact between the vehicle and

the ground, there is a regulation in this respect governing

the minimum level of conductivity of tyres.

•When carbon black is used as a reinforcement f iller, tyres

normally have an acceptable level of conductivity.

•When other reinforcement f illers are used, such as silica,

the level of conductivity may decrease. It then becomes

necessary to apply design features to restore conductivity

to an acceptable level.
