Although ordinary rubber is insulator, the rubber tyres of air crafts are made slightly conducting. Why?

Explanation

### Step-by-Step Solution:

1. **Understanding the Properties of Rubber:**
- Rubber is generally known as an insulator, meaning it does not allow electric current to flow freely through it. This property is crucial in many applications where electrical insulation is needed.

2. **Context of Aircraft Tires:**
- Aircraft tires are subjected to high speeds and significant friction when the aircraft takes off and lands. This friction generates heat and can also lead to the accumulation of static electric charges on the surface of the tires.
