I have to compare and contrast three types of tires, and relate them to physics.
I've chosen:
<li> Racing tires
<li> Winter tires
<li> All season tires
I've chosen to compare them on:
<li> Tire tread pattern
<li> Rubber compound
<li> ???
As you can see, I need something else to compare. I thought of air pressure but that's not really determined by the type of tire...any ideas?
Thanks.
I suggest you also look into the very important differences between radial and bias-ply construction of the underlying layers:

When comparing the three types of tires (racing, winter, and all-season) in relation to physics, you have already chosen two important factors to compare: tire tread pattern and rubber compound. These factors greatly affect the performance of the tires in different conditions.
To add another element for comparison and relation to physics, you can consider the coefficient of friction. The coefficient of friction is a physical property that determines how well a tire grips the road surface. It is affected by multiple factors, such as the materials used in the tire, the weight of the vehicle, and the surface conditions.
When comparing different types of tires, you can explore how the coefficient of friction varies for racing, winter, and all-season tires. Racing tires typically have a higher coefficient of friction because they are designed to generate maximum grip on a racetrack. This allows for better acceleration, braking, and cornering performance. Winter tires, on the other hand, have a specialized tread pattern and rubber compound that helps them maintain traction on snow and ice, thus increasing the coefficient of friction in icy conditions. All-season tires, as the name suggests, aim to provide a balance between performance in different weather conditions. Therefore, the coefficient of friction for all-season tires would fall somewhere between racing and winter tires.
To determine the coefficient of friction, you can refer to technical specifications provided by tire manufacturers or consult test results from independent organizations that evaluate tire performance. These tests usually include measurements under different road conditions and temperatures to assess the grip and traction provided by different tire types.
By comparing and contrasting the coefficient of friction for racing, winter, and all-season tires, you can discuss how the physics of tire-road interaction affects their performance in different situations.
