1. Better air pressure retention is the main reason to use nitrogen. The single biggest reason for tire failure is lack of maintenance of tire pressure. Oxygen in compressed air can permeate the tire wall reducing tire pressure. With nitrogen, diffusion is 30 to 40 percent slower than oxygen. As a result, nitrogen maintains tire pressure longer than ambient air.
2. Enhanced fuel economy. By maintaining tire pressure will boost fuel economy. Nitrogen disperses heat more quickly than ambient air. By restraining the heat in the tire and reducing rolling resistance, you get better fuel economy.
3. Longer tread life. With quicker heat dispersion, you get a cooler running tire which helps extend tread life and reduce tire failure. Nitrogen also reduces oxidation which can not only lead to tread separation and belt failure but, when combined with moisture, corrode rims. Moisture can result in rust flakes that can fall into the valve stem, block the valve and cause under-pressurization. It can even cause the valve stem itself to rust.
4. Slows chemical aging. Filling a tire with nitrogen also significantly slows the chemical aging process of the tire’s rubber components. This leads to fewer catastrophic failures like ka-boom blowouts. Slower aging lengthens tire core life.
I put it in my tires but I have a bottle that I use for industrial laser operation. Is it worth $64.00 to do a bus, maybe.
