One way to tell if your rear tire has gone flat while riding is if:

If your rear tire fails, the back of your motorcycle will likely jerk from side to side. It is rare for motorcyclists to actually hear a tire fail.

• There is a hissing noise coming from the rear of the bike.
• The back end is jerking from side to side.
• You are unable to accelerate.
• The rear brake does not work.
