Any idea of what might be the cause of your subjective feeling of a smoother ride? Have you heard similar reports from friends or professionals? Without any experience with Nitrogen, what exactly convinced you to put the gas in your tires? Just curious!
Don't know the science to support smoother ride feeling.
Have it because our service garage/tire people are straight up & enthusiasts & it was free.
Quite a bit for & questioning it on the Internet.
Suggest you Google it as apparently can't post links here.
Here is one extract:
Drexan, a distributor of Parker Hannifin equipment in Canada, has released results from a nitrogen tire inlation trial in a long haul truck fleet. This study was partially funded by Transport Canada, the government department responsible for developing regulations, policies and services in the transportation industry.
The results of this analysis were remarkable, and recently presented at the Clemson Tire Conference:
• When compared to historical data, nitrogen tire inflation provides a 6.1% improvement in fuel efficiency when compared to a fleet with no tire pressure maintenance program
• When compared to historical data and an in-trial control, nitrogen tire inflation provides a 3.3% improvement in fuel efficiency when compared to a fleet using air inflation and a tire pressure maintenance program.
• When compared to the in-trial air control, nitrogen filled tires provided an average tread life improvement of 86% when compared to a fleet using air inflation and a tire pressure maintenance program.
• The study infers that casing life improves (increasing retreadability) and tire failures decrease.
The economic implications of nitrogen tire inflation were also impressive:
• Saved 110,000 gallons of diesel over the 9 month period ($285,000 US)
• The value of the extended tire life was not monetized, but could be easily calculated for any fleet that knows their cost/mile for tires.
• Greenhouse gas emissions were reduced allowing them to be exchanged for revenue on carbon trading sites.
This study was conducted over a 9 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. It covered the coldest and hottest months of the year to minimize climate variances. The analysis isolated inflation gas as the primary basis for any change in the mean.
