Are Wider Tyres BETTER For Brake Performance?

And does a 'slip ratio' actually measure how much your tyres is slipping or skidding along the road under braking etc, or something else?

In this module, just one of many taken from the HPA Brake System Design and Optimization course, you will explore the fundamental mechanisms behind how tires generate longitudinal force. The amount of longitudinal force a tire can generate while braking depends on various parameters, with the slip ratio being the primary influencer. Vertical load, slip angle, camber angle, temperature, inflation pressure, and vehicle speed also play important roles.

For every set of conditions, there exists an optimal slip ratio that maximizes the generation of longitudinal force, also referred to as braking force. The slip ratio experienced by the tires is primarily determined by the driver's application of brake pedal force.

Furthermore, we will discover how the coefficient of friction produced by the tires during braking is sensitive to the vertical load.

Don't worry! All the basics like 'what even is vertical load and longitudinal force' are also covered before getting stuck into things!
