CHAMPIRO ECO has been developed and tested in co-operation with TUV SUD Automotive, a long-standing testing partner to GT RADIAL. Due to its innovative technology the CHAMPIRO ECO already meets EU tyre regulations that will come into effect in 2012. The œS and œW displayed on its side confirm that it undercuts the threshold for noise development (S) and traction in wet conditions (W). In the third EU category that evaluates rolling resistance and fuel consumption the CHAMPIRO ECO gets a preliminary C on a scale from A to G (measuring methodology still to be confirmed). This rating puts the new GT RADIAL tyre among Europe's very best. The new tread design reduces the CHAMPIRO ECO's rolling resistance by up to 20% compared to its predecessor model. Depending on vehicle and driving style, this reduces fuel consumption by up to 4% “ and the environment benefits from the low CO2 emissions.
