I can't agree, but not because I'm trying to argue or be a d!ck. Heat related damage results from being underinflated, regardless of which gas is in the tire. Like 32fever points out, there's not THAT MUCH difference between nitrogen and "air" to be some major miracle.

I started using nitrogen for my race cars. And having a small and medium tank of nitrogen was easier than carrying and plugging in a compressor for air. I also get my passenger tires at Costco, so it all worked out when they started using it.

If people managed their tire pressures frequently, and perhaps every tire filling station had a functioning dryer on the line, nitrogen wouldn't be necessary. The big benefit to nitrogen is the reduced moisture content, and the delayed psi loss over time.

Has anybody actually watched the air coming out of a hose at a filling station? I swear there were times I thought there was more water coming out than air.
