The combination of tyre temperature, road conditions, and weather conditions is crucial because all three factors significantly influence a tyre's adhesion to the road surface.

1. Tyre Temperature: As tyres heat up from use, they can become more pliable and provide better grip. However, if they are too cold, they might not reach optimal adhesion.

2. Road Conditions: The state of the road—whether it's dry, wet, icy, or uneven—affects friction. For example, wet roads reduce grip significantly and can lead to aquaplaning.

3. Weather Conditions: External factors like rain, snow, or even dirt on the road can compromise traction. Different weather conditions require specific tyre types (e.g., winter tyres in snow) to maintain safety.

Understanding these three elements is essential for safe driving, as outlined in the German road traffic regulations. Proper tyre performance ensures better control of the vehicle and minimizes the risk of accidents.
