Cracks can appear on the surface of the tire and may worsen over time. A study by the Bicycle Safety Institute reveals that tires showing extensive cracking can fail during use, posing serious risks. -
Brittleness:
Brittleness indicates that the tire has lost its elasticity. A tire that feels rigid when flexed may be undergoing dry rot. Rubber typically retains some flexibility; when it becomes hard and unable to grip the surface properly, it can lead to decreased traction and handling issues. Coined as “rock-hard,” this condition contributes to dangerous riding experiences. -
Fading Colors:
Fading colors on bike tires often signal prolonged exposure to sunlight and environmental factors. Discoloration from black to gray or brown shows the rubber’s degradation. Such fading can suggest potential weaknesses in the tire structure, which may eventually lead to punctures or blowouts, as noted in research by the American Bicyclist Association. -
Loss of Flexibility:
Loss of flexibility is a critical indicator of tire condition. Tires should maintain a certain pliability to absorb shock and provide traction. If a tire feels stiff and does not conform well to the surface, it may soon lead to tire failure. Experts recommend periodic inspection for flexibility, especially in tires older than five years.
Regular checks for these signs can help ensure safer rides. Proper tire maintenance and timely replacement are crucial for riding safety.
What Causes Bike Tires to Dry Rot?
