Our two-year warranty program covers Panaracer products that legitimately fail due to a manufacture defect. Use your judgment when assessing whether your product is likely to be covered under the warranty. We do NOT cover products that no longer work due to wear and tear. Wear and tear is damage that naturally and inevitably occurs as a result of normal use. Tyre compounds and fabrics will naturally wear out, deteriorate and fade over time. And while we choose the best materials available for the application, all materials degrade over time with use and exposure to the elements. If after assessment, Panaracer determines your tyres have degraded due to reasonable wear and tear and deems the returned product ineligible for warranty repair or replacement, we will contact you to discuss available options we may have for you.
