Developed as a fitment for trailers and semi-trailers, the ST:01™ Neverending™ Energy™ aims for maximum efficiency as far as fuel consumption and safety are concerned.
The new Pirelli tyres introduce considerable benefits for fleets because on a vehicle formed by tractor unit and semi-trailer the tyres fitted to the latter generate 50% of the total rolling resistance of all tyres.
The line developed by Pirelli researchers combines safety with energy efficiency, whilst maintaining the high mileage and long life you would expect from a truck tyre.
The innovative tread pattern and double-layer compound with a high percentage of silica are patented Pirelli technology. In particular, the compound used to produce the ST:01™ Neverending™ Energy™ cuts heat generation and, therefore, rolling resistance, whilst ensuring improved tear resistance and higher mileage.
ST:01™ Neverending™ Energy™ also boasts new profiles and innovative sidewall and bead geometry.
Size 385/65 R 22.5 will be on sale in European markets by the end of this year, whilst 385/55 R 22.5 will be available from January 2013.
