Why the special tyres of air-crafts are made conducting?

Tyres are usually made of rubber which is an insulator. But the tyres of aircrafts are intentionally made conducting to avoid damages caused by electrostatic sparks. While travelling at high speeds, the body of the air craft gets charges die to friction. If the tyres are not made conducting, huge potential differences may develop and may produce dangerous sparks which can burn the entire plance if caught up with fire.
