Bridgestone Bulletin on Nitrogen Inflation - NitroFill
August 19, 2018
Is nitrogen inflation new?
No, it’s been used in off-highway tires, aircraft tires and racing car tires for years.
How does nitrogen help?
Nitrogen permeates through rubber more slowly. It might take six months to lose 2 psi with nitrogen, compared to a month with air. And nitrogen is far less reactive. It doesn’t cause rust and corrosion on steel and aluminum and it doesn’t degrade rubber. Wheel surfaces stay smooth and clean, rubber remains supple and resilient. Inflation losses are minimized – and retreadability is enhanced.
Are there other benefits to nitrogen?
Air is full of water vapor called “humidity”. And compressed air concentrates the water in it. Draining water from your air lines helps, but unless you have an efficient air dryer, chances are there’s still water in your compressed air.
