Fowler Welch, a UK-based supply chain logistics provider, has carried out a comprehensive test of Bandvulc and Continental low-rolling-resistance tires.
The collaborative trial, carried out under strict conditions at Millbrook Proving Ground, used two DAF 6×2 tractor units with trailers, with one vehicle acting as a control subject while the other used different combinations of Bandvulc and Continental tires over the five test rounds. During the final round the vehicle tires were deflated by 20% in order to assess the contribution of tire pressure on fuel consumption.
The results showed that the use of low rolling resistance tires – Continental Efficient Pro on the steer axle and Bandvulc BDF5 on the drive axle – provided an increase of 5% in miles per gallon compared to the OEM fitment. The data also revealed that the deliberate reduction in tire pressure resulted in a 2% decrease in miles per gallon, something that would be detected by the ContiPressureCheck system.
“Miles per gallon figures are critical to operational costs and we are determined to get the most out of every drop of fuel. Not only does it result in undeniable cost savings, but also significant reductions in CO2 emissions. After implementing a number of fuel-saving measures across the business, we asked ourselves, ‘Where else can we maximize our economy?’ The obvious answer was tires,” explained Maurizio Romano, head of fleet strategy at Fowler Welch.
“We were extremely impressed by the professional way in which Bandvulc organized these tests, and equally by the vast difference that low rolling resistance tires offer. The figures speak for themselves and offer real food for thought as we look to adapt our tire policy.”
