Nitrogen vs. Oxygen

With the implementation of the TREAD act all 2007 and newer vehicles under 10,000 lbs now utilize tpms sensors located in the wheel. Reduction of as little as 5 psi will trigger driver warning light. nitrogen is less likely to migrate through rubber pressure is more stable. nitrogen is an inert gas and oxygen free, it is impossible for oxidation to occur. no oxygen: no oxidation, no tire rot, no interior wheel or valve rust or corrosion, no water less failures of government mandated expensive tire pressure sensors. As for the cost if a shop is forced to buy a 12,000 dollar piece of equipment with a limited service life should they not be reimbursed for the the use of the equipment???????

There's nothing in TREAD that requires nitrogen fills for tires. Shops who spend money on that equipment do so by their own choice, and are not forced to by the legislation. They are motivated by making a profit, not by compliance.

As already stated, the atmosphere is 78% nitrogen. The idea that pure nitrogen prevents oxidation from the inside of the tire totally discounts the fact that there is oxygen in the air outside of the tire, surrounding everything. Unless, of course, you're driving in a vacuum.

And these "expensive" tire pressure monitoring sensors you speak of? Replacements are from $25 - $40 at Amazon. Breaking the bank, obviously.
