Causes of Cracks

• The rubber that tires are made of may crack for a number of reasons. The rubber deteriorates because of exposure to sunlight and a variety of chemicals. Chemicals come into contact with the tires from products used to clean and maintain the motorcycle as well as materials on the roadway.
  
  

Preventing Cracks

• The good news is that one of the best ways to prevent tire deterioration is to ride the motorcycle frequently. Riding the bike helps to warm the rubber which can help the anti-aging materials in the rubber to work properly. Tire manufacturer Goodyear recommends cleaning tires with soap, water and a bristle brush to prolong tire life.
  
  

Dealing with Cracked Tires

• Small cracks in tires may appear harmless, but the cracks may run deep into the rubber or signal that the material is failing. As a sudden loss of air pressure in a motorcycle can cause a loss of control and catastrophic injuries. Tires with cracks should be replaced.
