Guy Heywood, commercial director of Michelin Tyre, confirms that the shift is being driven by the growth of Euro 6 registrations and operators “realising the total cost of ownership benefits” offered, compared with traditional, low aspect ratio 295/80 R 22.5 tyres.
Michelin points to figures released by the European Tyre & Rubber Manufacturers Association, which show the 295/80 R 22.5 – previously the firm favourite of UK hauliers – in decline by three percentage points since 2010.
Meanwhile, over the same period, 315/70 R 22.5 tyres have increased their share by 3.4 points, and the 315/80 R 22.5 by 0.6 points.
“More and more operators are realising that moving to 315/70 tyres can reduce their running costs and open access to the very latest generations of products, which tend to be developed in this size,” states Heywood.
“Our own surveys, and trials we've carried out in conjunction with truck manufacturers, have shown the benefits offered by 315/70 tyres – particularly in terms of fuel efficiency and tyre longevity,” he continues.
“Now operators are experiencing these benefits in their own fleets too, it’s driving one of the most notable changes in tyre buying habits we’ve seen this side of the millennium.”
