Red Seal Motorcycle Technician Practice Exam

What should be the ideal tire pressure for motorcycles?

1. Always maximum tire pressure listed on sidewalls

2. Manufacturer-recommended tire pressure

3. Lower than average to improve grip

4. Variable based on rider weight

The correct answer is: Manufacturer-recommended tire pressure

The ideal tire pressure for motorcycles is the manufacturer-recommended tire pressure. This specification is provided by the motorcycle manufacturer based on extensive testing to ensure optimal performance, safety, and handling characteristics of the motorcycle. Maintaining the recommended tire pressure helps in achieving the best contact patch between the tire and the road, which enhances grip, stability, and tire longevity. Using the maximum tire pressure listed on the sidewalls is not advisable as it might lead to a harsh ride, reduced traction, and uneven tire wear. Likewise, opting for a lower tire pressure can indeed improve grip in certain conditions, but it can also result in quicker wear, increased heat buildup, and compromised handling, particularly in high-speed situations. Variability based on rider weight can influence tire pressure settings, but these adjustments should still adhere to the guidelines provided by the manufacturer to maintain the overall safety and performance of the motorcycle.
