When a motorcycle's rear tire goes flat while traveling at 70 mph, several things can occur:
Loss of stability: A sudden loss of tire pressure can lead to instability and a change in the motorcycle's handling characteristics. The rear end of the bike may become unstable, causing the rider to experience wobbling or difficulty in maintaining control.
Difficulty in steering: With reduced traction on the rear tire, steering inputs may become less responsive. The motorcycle may feel sluggish and have a delayed response to rider inputs, making it challenging to maintain a desired path.
Increased risk of loss of control: The loss of traction can result in the rear tire slipping or sliding, particularly during cornering or braking. This can lead to a loss of control, potentially resulting in a skid or even a high-side or low-side crash.
Impact on braking distance: A flat rear tire can significantly affect the motorcycle's braking performance. With reduced traction on the rear wheel, the ability to brake effectively and safely may be compromised, potentially leading to longer stopping distances and an increased risk of collision.
Given the potential dangers of riding with a flat tire, it is crucial to respond calmly and follow the recommended safety procedures. This includes gradually reducing speed, maintaining a stable riding posture, and carefully bringing the motorcycle to a stop in a safe location off the road.
