A preferred joke in the 1960s at full service gas stations was'filler up with Ethel and change the air in my tires.' Today with the cost of petrol approaching $3.00 per gallon, why not replace the air in your tires. Not with air but with nitrogen. Filling your tires with nitrogen rather than air will improve gas mileage, help maintain correct tire pressure, keep tires 25% cooler, improve handling and performance and prolongs the life of your tires. NASCAR drivers use nitrogen in their tires for safety reasons, you can too.
Why should you stop putting air in your tires! Compressed air you find at tire shops, gas stations and the compressor you use at home have a high concentrations of water vapor. Squeezing air concentrates the water in it and unless actually efficient air dryers are used possibilities are there is water vapors in your tires. Water vapor absorbs and holds heat. This wet air and heat can increase the pressure in your tires, causing highway blow outs, and is one of the reason you should take a look at your tire pressure when they are cold.
This article is not about the nitrogen. It's truly about reducing oxygen and water vapor in your tires. The air in our tires is composed of 78% nitrogen, 21% oxygen and about 1 percent water vapor and other gases. When pure dry nitrogen is used to replace the air in your tires it improves fuel efficiency, handling and it will extend the life of steel rims or custom wheels and tires. By reducing oxygen and water vapor in your tires from 22% to less than 7%, your tires will maintain pressure 3 to 4 times longer. Plus it will keep you safer on the highway.
How does oxygen and water damage my rims and tires? Oxygen, particularly at high temperatures and pressures, corrodes aluminum, steel wheels and rubber. This process is called oxidation. When oxidization happens small particles of rust and aluminum oxidation in your steel or aluminum wheels can clog valve stems, causing them to leak. The oxidization could cause the surfaces of your wheel flange and tire beads not to seal correctly causing another leak point.
Oxygen can also age the thin layer of rubber called the inner liner or radial ply. As the inner liner ages, more and more air migrates through the rubber, causing additional pressure losses. As oxygen migrates through rubber it can come in communication with steel belts and the steel bead causing them to rust.
While both nitrogen and oxygen can migrate through rubber, nitrogen does it much slower. It would take six months to lose two pounds of nitrogen, compared to less than a month with wet compressed air. Dry nitrogen does not cause rust and corrosion on steel rims or aluminum custom wheels, and it does not degrade rubber like wet compressed air.
Where am I able to get nitrogen for my tires? Nitrogen is becoming very popular with long haul trucking. Some van stops have nitrogen available for these big rigs either free or by paying a small fee. They use the same type pay stations that you see at gas stations except they are marked'Nitrogen'. These nitrogen stations are then hooked up to massive nitrogen cylinders near by.
you may also purchase your own little cheap Nitrogen Tanks and have them filled at welding supply stores in your area. Another source for tiny nitrogen tanks is Paint Ball supply stores either local or online. EBay is a superb source. These small nitrogen tanks can be filled at welding supply stores and then simply plumbed to fill your tires. Watch out when handling these little nitrogen tanks as they can be filled to as much as 3k psi. Also make sure the nitrogen tank you purchase has a regulator attached and it is set for about 50 psi.
Filling your own new tires with nitrogen is a simple process. Boost one tire until it just clears the ground, remove the tire valve stem and allow the air in your tires to escape. Once all the air escapes install a new valve stem. Then simply fill your tires with nitrogen from your small nitrogen tank. Repeat the process with the other 3 tires. Don't forget your spare! Your tires should now have about 95% dry nitrogen and you have noticeably reduced all the hazards and oxidization Problems discussed above.
if you're the owner of a tire store and would like to provide nitrogen for your clients buy an Ingersoll Rand Nitrogen Tire Inflation System.
