Vipal Erope reports that its VRT3 tread has demonstrated 8 per cent better mileage when tested against similar competitor treads. To make its point, Vipal used the streets of Puglianello, Italy to host a battery of tests in what the company describes as the first performance comparison in Europe. Such a claim must refer to the comparative testing of pre-cure retread material brands, as there have been numerous comparison tests between new tyres.
