Gyeon Q² Tire is an innovative SiO2-enriched rubber coating, and redefines what we can expect from products designed for tyres. Unlike traditional tyre dressings, which sit on the surface of the tyre and quickly wash away, Gyeon Q² Tire penetrates the surface and bonds to the rubber at the molecular level. As a result, it's far more durable, and should thus be classed as a protectant rather than a dressing. We've been using it on our daily drivers for several years now and find that each application typically lasts for a minimum of four weeks, even in wet weather. However, this can be extended to six weeks or more if it is layered and heated gently with a heat gun.
