Vacu-Lug has been pioneering a new low-rolling resistance compound for its Duramold remould tyres, which in addition to providing operational and environmental benefits are actually green in colour. The new tyres, which are now on trial with a major UK operator, have been produced using a specially-formulated compound which replaces the traditional carbon black with a mix of silicas. These silicas enable the colour to bond with the polymers in the compound, resulting in a rubber that has been independently proven in trials conducted by TARCC (Tun Abdul Razak Research Centre, the UK-based research arm of the Malaysian Rubber Board) to be more environmentally-efficient in a number of ways:
- The silica-based compound is harder and tougher than a standard tyre, meaning there is less deformation in the crown area, which significantly improves the tyres’ rolling resistance by up to 30 percent.
- Less movement in the tread means there is less heat build-up, thereby prolonging tyre life.
- The harder compound theoretically improves the wear characteristics of the tyre over a period of time.
- The silica-based compound shows a much improved snow and ice behaviour and better wet skid properties, with abrasion remaining constant.
- The tread surface of the high-silica compound is harder and microscopically rougher than the carbon black-based compound and, as a result, increases surface grip.
“In addition to longevity and performance benefits, the use of these environmentally-efficient tyres on all axle positions can make a significant difference in fuel consumption,” says Tim Hercock, Managing Director for Vacu-Lug Tyres Limited. “A reduction of ten percent of rolling resistance on a complete vehicle results in approximately a three percent reduction in fuel consumption.
“Therefore, if the potential 30 percent improvement, as determined by TARCC in the laboratory, is translated through the use of the above formula, operators could theoretically see fuel consumption decrease by as much as nine percent.
“This would mean a vehicle travelling 150,000 kilometres per annum with a fuel consumption of 30-litres per 1,000-kilometres could obtain a nine percent reduction in consumption, meaning the annual savings could be as much as £4,050.00 (assuming fuel is £1.00 per litre) and an according carbon footprint reduction of 10.8 tonnes of carbon dioxide per vehicle.”
