On any given "normal" day, other pollutants (water vapor, carbon monoxide, dust, methane, etc.) make up just over 1% of the air. Only 0.2% is water vapor. Of course, it's more if It's foggy or raining. It's still not worth converting to Nitrogen to fill your tires unless you race. Plain and simple. Believe what you want and pay more if you want--Free country. If you're really worried about it, use a separate small (5-10gallon) portable air tank. Fill that tank on dry days.Nitrogen due to the way its made has a lot less water in it than compressed air from a well maintained system. Water's vapor pressure increases as it heats up, so the pressure variation between cold and warm tires is increased.
I still have my two-stage drier on my shop compressor. I used it for painting and shop tools but never worried about using an undried line for blow guns and other air uses--Tires, jacks, etc. It's not worth the concern.
