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:
