Secure Ride 8.1, 11.02.09

Secure Ride Appendices 04.26.11 3There is some confusion in the marketplace about what is the correct tire purity for nitrogen inflated tires. The market has moved toward a 95% in tire purity as the standard, but is that the best fit for the application?

Based on partial pressures, the ideal purity in a 32 psig passenger tire is 93.6% Here are the calculations that support 93.6%:

O2 makes up 20.9% of atmosphere, yielding a partial pressure of (0+14.7) 0.209 = 3.07 in the atmosphere.In an air filled 32 psig tire, the partial pressure of O2 is (32+14.7) 0.209 = 9.76 in the tire. The pressures want to equalize, so O2 from the tire leaks to atmosphere.In a 93.4% nitrogen filled 32 psig tire, the partial pressure of O2 is (32+14.7) 0.066 = 3.07 in the tire. The pressures are equalized, so the O2 is much more content in the tire and doesnt look to escape.

What is the harm then if you are higher than 93.4% in a 32 psig tire? Well, believe it or not, NHTSA has proven that O2 will begin to leak back into the tire. 1

Time is Money: In a test conducted on a P245/50 R20 equipped vehicle, the N2G took 10:00 to inflate the 5 tires to 35 psi. The same vehicle was completed in 4:15 with the Kenvo 930.

Larger and ton truck tire application time to 80 psi is 2-3 times longer using the N2G system.

Purity in both systems is accomplished only with a properly filtered air supply.
