Michelin has launched the next-generation version of its popular 315/70 R22.5 X Line Energy multi-position tyre, commonly specified on the steer axles of Euro VI tractor units.
The new 315/70 R22.5 X Line Energy Z2 – ‘Z’ meaning multi-position, and ‘2’ marking the second generation of this product – becomes Michelin’s most fuel-efficient tyre in this key size to-date, rated ‘A’ for rolling resistance.
Designed specifically for trucks and coaches used on long-distance routes, and where the majority of time is spent travelling at sustained high average speeds, the new tyre builds on the already impressive fuel savings of its predecessor, which was rated ‘B’ for rolling resistance.
Now, by upgrading to the X Line Energy Z2 on the front axle, operators can save an additional 0.4 litres per 100 km, while also cutting CO2 emissions by 10g per km.
Chris Smith, Sales Director B2B for Michelin in the UK and Ireland, says: “We spend more than €600m on research and development every year, and it’s this continued level of investment which has helped us to push the limits of rolling resistance even further to help operators unlock greater savings.
“Crucially, we’ve achieved this improved Grade A rolling resistance without affecting the longevity of the tyres, by integrating a high percentage of silica in the tread. The new tyre has huge fuel-saving potential, combined with the safety, durability and longevity that is the hallmark of Michelin. We’re confident you won’t find a more fuel-efficient tyre in the market.”
Available initially as a 315/70 R22.5 fitment, the first X Line Energy Z2 features Michelin’s Regenion technology – guaranteeing strong performance throughout the entire lifespan of the tyre, thanks to a self-regenerating tread pattern which helps to maintain high levels of grip, traction and safety.
The tyre also benefits from a robust and proven tyre architecture thanks to Michelin’s InfiniCoil technology, which has featured in the X Line Energy range of tyres since 2016. This comprises a continuous steel cable several hundred metres long wrapped around the crown block.
