| Jun 26, 2020 at 4:56 | comment | added | Stu Smith | As made clear in the link provided by Greg Hewgill, there are valid reasons why commercial airliner tyres would want pure nitrogen. The same reasons might apply to a racecar. But for the majority of personal cars and GA aviation, plain old air, which is 78% nitrogen, seems just fine to me. | |

| Jun 25, 2020 at 5:17 | comment | added | jamesqf | @John K: True. And consider that if oxygen does diffuse out of the tires faster than nitrogen does, after topping up the pressure a few times, the gas in there is going to be pretty close to 100% nitrogen anyway. | |
| Jun 25, 2020 at 4:20 | comment | added | John K | Well, nitrogen in car tires is called "marketing" where there is money to be made on something completely worthless, from an actual real-world practical standpoint. because people hear that racing and airliners do it. | |
| Jun 25, 2020 at 3:25 | comment | added | Dean F. | “ It comes down to what's available.” - Interestingly enough, I can get my car tires filled with nitrogen at my local Costco any time I want. But, my local FBO fills aircraft tires with a handheld, battery operated compressor. My local flying club uses a 1-gallon mini-compressor. Doesn’t that seem a little backwards? I wonder if the FBO saves the nitrogen for their jet traffic? | |
