Radburg V71 - Ecology and economy. Radburg V71 is an affordable and environmentally friendly alternative. A retreaded tyre reuses the majority of the tyre, thus polluting the environment significantly less than a brand new tyre. Unlike most other environmentally friendly products, a retreaded tyre is also very affordable, making it a very viable option for the environmentally and price-conscious motorist. For its price, the Radburg offers very good grip and driving characteristics, as well as a comfortable ride. Only high quality frames have been used in the manufacture of this European tyre.
