Michelin tyres go the extra mile for Prestons of Potto31 July 2012

Northallerton-based Prestons of Potto is seeing the direct benefits of moving from 295/80 R22.5 drive axle tyres to 315/80 R22.5s, after the highest mileage tractor unit in an initial 20-vehicle trial clocked-up more than 500,000km (524,137km) before its Michelin XDN2 Grip drive tyres needed replacing.

"I saw the truck in our workshop shortly after it had passed the half a million kilometres barrier," explains impressed fleet engineer Paul Barker. "The tyre performance was so remarkable I double checked our records, and the manufacturing date on the sidewalls, to make sure these were the same tyres.

"We've been fitting Michelins for years, so we're used to our tyres lasting the distance, but this was particularly notable. We typically get around 380,000 to 400,000km from our 295/80 XDN2 Grips – this larger size tyre has delivered a 25% increase in tyre life."

The 315/80 R 22.5 Michelin XDN2 Grip tyres were specified on 20 new Scania R480 6x2 tractor units which entered service during February and March 2010. The 524,137km was achieved by all four drive tyres on NJ10 HSN, which has to-date covered the highest mileage of the 20 vehicles, after being double-shifted during its first 18 months on the fleet.
