Tire antenna tread — tire grounding strip

Tire antenna tread is a grounding strip to dissipate static charge

Tire makers have modified the rubber compounds in their tires to decrease rolling resistance and increase traction. To accomplish that they’ve added silica and reduced carbon black. However, that has caused some problems with static electricity buildup in the vehicle.

In the past, carbon black in tires helped dissipate static charge. With the reduction in the use of carbon black, customers started to complain about static shock when moving in and out of the vehicle.

Tire makes add a carbon black antenna tread

The solution to static buildup is a ground tread referred to as an antenna tread. At the center-line of the tire, tire manufacturers embed a thin continuous strip of conductive rubber so it’s always in contact with the road to dissipate static buildup.
