Final answer:
Worn or bald tires do increase the chance of having a flat tire and increase stopping distance. More friction is desirable in certain situations to enhance stability and reduce the risk of slipping or sliding.
Step-by-step explanation:
Worn or bald tires increase the chance of having a flat tire and increase stopping distance. This statement is true.
Worn or bald tires have reduced tread depth, which means they have less grip on the road. This can lead to an increased risk of having a flat tire if the tire gets punctured or damaged. Additionally, worn or bald tires have reduced traction, which results in a longer stopping distance when brakes are applied, increasing the time and distance required to bring the vehicle to a complete stop.
A similar example where more friction is desirable is when walking on a slippery surface. Wearing shoes with a good grip or using traction aids increases friction between the surface and your shoes, reducing the risk of slipping and increasing your stability.
