ARTICLE - When should I change my motorcycle tire?
Most on-road tires have built-in tread wear indicators. When the tire is worn down to the indicators it is time to change the tire. In this case it is getting close to time to change the tire. It is not quite down to the wear bars.
For on-road tires, another way to check tread depth is stick a penny Lincoln head first into the tread. If you can see all of Lincoln’s head then it is time to change the tire.
Often there are tire wear indicators on multiple parts of the tire. Check them all to see if the tire is close to the wear bars.
