NITROGEN INFLATION: MORE EVIDENCE FOR THE JURY - Test results from a Winnipeg fleet trial support nitrogen inflation

摘要

This summer, Burnaby, B.C.-based Drexan Corporation released results of what could be the biggest comparison of nitrogen- and air-filled tires in normal fleet operations in Canada. Based on data collected from 1,988 wheel positions and 9.8 million tractor kilometres driven over six months in 2006, Drexan reported an 86% increase in tread life and 3.3% better fuel economy for the nitrogen inflation tractor/trailer group.
