Tire Inflation: Nitrogen vs Air

At work I don't have to worry about tires, but we do use it in the hydraulic accumulators. The pressure in these is checked every 500hr and when the seasons change. We have a chart that we work off to set the pressures.

I don't any advantage in running Nitrogen in my car, even when I was living in Northern BC, where the temps got as low as -40. The wheels were square for a bit but you just lived with it. I don't think nitrogen filled tires would have changed that.

But it's your money
