Well, not exactly. The 35 is pressure, not mass. If you figure the mass of the air in an A tire and then the equivalent mass of the same volume of 35psi compressed Helium the tire would be about 25 grams lighter. Less than an ounce difference.

I'm sure every tire shop has an air/water separator on their air lines, so you're not going to get much, if any, water vapor in your tires. If you have your own compressor at home, you do own an air/water separator, don't you? Unless you take on-ramps at 120 MPH, I doubt you will notice a pound or two difference in air pressure. Have you ever seen a tire 'degrade' on the inside from plain air like the nitrogen scammers claim? Me neither! I've seen a lot of cars stored for several years, some many years, and there is still air in the tires (not nitrogen, but plain air)!
One of the largest tire retailers around the Southwest, Discount Tire, does not use nitrogen. A few years ago General Motors sent a bulletin to its dealers advising AGAINST the use of nitrogen.
In short, using nitrogen in your tires is nothing but a money wasting rip-off!
