Motorcycle Permit Practice Test

When riding on a wet road, which tire pressure condition is ideal?

1. Over-inflated tires

2. Under-inflated tires

3. Properly inflated tires

4. Random tire pressures

The correct answer is: Properly inflated tires

Properly inflated tires are vital for maintaining optimal grip and handling when riding on wet roads. Adequate tire pressure ensures that the contact patch—the area of the tire that makes contact with the road surface—is maximized, which is crucial for effective traction. When tires are at the correct pressure, they function as designed, allowing for better water displacement and decreasing the likelihood of hydroplaning, which occurs when a layer of water builds between the tire and the road. In contrast, over-inflated tires can lead to a reduced contact patch, making it more challenging for the tires to grip the road, especially in wet conditions. Under-inflated tires may also fail to push water effectively away from the tire's surface, increasing the risk of losing traction. Having random tire pressures introduces uncertainty and can lead to uneven handling and reduced safety. Therefore, riding with properly inflated tires is essential for maximizing safety and performance on wet roads.
