To understand why **rigid pavement like concrete** offers better grip for tires, it is important to consider how tires interact with different surfaces.

- **Tire grip:** The tread of the tires is designed to improve road grip. The grooves in the tread help the tire grip the surface better by channeling away water and preventing overheating.

- **Pavement surfaces:** A rigid pavement, such as concrete, provides a uniform and stable surface that allows tires to maintain constant and effective contact. This improves grip, as the surface does not have irregularities that could reduce contact with the tread.

- **Comparison with other pavements:**
- **Cobblestones** can have gaps and uneven surfaces, which decrease effective contact with the tires and, therefore, grip.
- **Shiny and polished slabs** can be slippery, especially when wet, which significantly reduces tire grip.

Therefore, rigid concrete pavement is the best option to ensure good tire grip, reducing the risk of skidding and improving driving safety.
