Benefits of tyre retreading:

*The benefits of retreading are  both environmentally friendly and cost-efficient! When the tread has worn off, only about 20% of the tyre is used up. The carcass, which represents about 80% of the tyre's value, can be re-rubberized for a "new tyre life".

* To produce a truck or bus tyre requires about 60-80 kg of rubber mixture. Retreading the tyre takes only about 15 kg of rubber. A considerable amount of raw materials can therefore be saved. In the EU, this equates to more than 300,000 tones per year!

 * To produce a car tyre requires about 28 litres of crude oil. To retread a car tyre, on the other hand, only 5.5 litres of oil are needed
