WASHINGTON (Nov. 6, 2006) — The Rubber Manufacturers Association (RMA) has issued a service bulletin, “Using Nitrogen to Inflate Passenger and Light Truck Tires in Normal Service Applications.”
The bulletin was issued because the use of nitrogen systems among tire retailers has increased recently, the RMA said. The inert gas has often been used in specialized tire applications such as aircraft, mining, racing and commercial use, the RMA noted, because it reduces the risk of internal combustion and variations in inflation pressures.
But nitrogen generally is not required for normal tire use, and depending on nitrogen alone to reduce inflation maintenance may lead to dangerous underinflation, the association warned. Other sources of pressure leaks, such as punctures, can negate the benefits of nitrogen, the association added.
“Whether inflated by air or nitrogen, regular inflation pressure maintenance remains critical and necessary,” the RMA wrote. “Use of nitrogen alone is not a replacement for regular inflation pressure maintenance.”
