Fact: This is mostly the result of a blow-out caused by excessive heat through under inflation or overloading. These pieces contain steel wires, which are not part of the tread. Just like for new tyres, treads are vulcanized to casings, not "glued". This bonding is actually the strongest part of a tyre.
Fact: Retreaded tyres are just as safe as new tyres. Adjustment percentages of retreaded tyres are about the same as new tyres. Retreading is the controlled process using high tech equipments. Properly maintained tyres, whether new or retreaded, do not cause accidents. Retreaded tyres are used safely everyday by ambulances, fire engines, school buses, and aircraft.
Tyregrip retreads often equal and/or exceed the mileage performance of new tyres. The mileage performance of a tyre is ofcourse influenced by many external factors like: application, load, road conditions, driving style, etc. Choosing the right product for your specific conditions is key for achieving optimal mileage performance.
