Yes, tires do get harder with age. Over time, the rubber compounds in tires break down and lose their flexibility due to exposure to heat, sunlight, and chemicals. This hardening process can reduce traction and increase the likelihood of tire failure. For safety, it is recommended to check your tires regularly and consider replacing them if they are more than 6 years old, regardless of tread wear.

Questions and answers

  1. Why do tires get harder as they age?

    Tires harden over time because the rubber compounds degrade due to exposure to heat, sunlight, and chemicals, which reduces their flexibility.

  2. How does tire hardening affect vehicle safety?

    Hardened tires lose traction, which can increase the risk of tire failure and decrease overall driving safety.

  3. When should I replace my tires based on age?

    It is recommended to replace tires if they are more than 6 years old, regardless of their tread wear, to maintain safety.
