Drexan Corp. recently conducted a double blind study measuring the effects of nitrogen tire inflation on tire life and fuel efficiency in a long-haul trucking fleet. Performance of nitrogen-filled tires was measured against performance of air-filled tires with and without a maintenance program.
Parker Hannifin, based in Haverhill, Mass., provided the nitrogen generator used during this study. The results of this analysis, according to Parker, recently were presented at the Clemson Tire Conference:
The study, Parker says, infers that casing life improves, increasing retreadability, and tire failures decrease. The economic implications of nitrogen tire inflation also were impressive, according to the company:
Parker says they study was conducted over a nine-month period in 2006 using a fleet comprising 70 long-haul tractors and 117 trailers, providing 1988 wheel positions. It consisted of 6.1 million tractor miles and 110 million tread miles, and it covered the coldest and hottest months of the year to minimize climate variances, according to the company; the analysis isolated inflation gas as the primary basis for any change in the mean.
Drexan is a manufacturer and distributor of many products, including Parker Hannifin’s Tiresaver nitrogen tire inflation systems. Drexan has locations across Canada with a representative and distributor network throughout North America. Drexan is Parker’s largest seller of nitrogen tire inflation systems in Canada.
