#1

Ordinary rubber is an insulator. But the special rubber tyres of aircrafts are made slightly conducting. Why is this necessary?


#2

During landing or take off, the tyres of aircrafts get charged due to the friction between tyres and ground. In case, the tyres are slightly conducting, die charge developed on the tyres will not stay on them and it finds its way to the earth.
