Why are tire tread and inflation especially important on a motorcycle?

1. Tire pressure and tread affect control only on motorcycles equipped with an anti-lock braking system
2. The condition of a motorcycle's tires is mainly cosmetic because suspension keeps the contact patches stable
3. They affect traction, steering, and braking with only two tire contact patches
4. A single tire inspection at the start of the riding season is enough unless a warning light appears
