Your experience with nitrogen filled tires
All,
This is my first car with nitrogen-filled tires, and still too new to draw any conclusions. So I would like to know, long term, is it worth it to keep filling them with N2 instead of air? Is tire pressure more stable with N2 instead of air? Hard to believe, given the relative small composition difference between air and pure N2. What has been your experience? |

Meh, my tires have mostly nitrogen now.

Thank you, both confirming what I suspected. With all physical properties of air vs 95% nitrogen so close, it's a scam for the likes of me who are regular, not race car, drivers.

Those with pure Nitrogen swear that there are no pressure variances from very cold to warm weather. Costco tire shops offer this for free when you get tires there. That means you have to go back there if you need more Nitrogen. Like others I wonder how pure N is added to purge regular air.

The reality is that the real problem with airing up tires with a conventional compressor is that you are putting water into the tire. Over time you can have a puddle of water inside the tire. So they compressor you use should have a Dryer system attached to make sure you're not adding water with every adjustment fillup. Of course the "nitrogen only service" is largely water free, so of course there's no chance of water pooling inside. So if you have a compressor at home, add a dryer attachment to it. If it's just a little dinky hand held, you might be taking a chance, but not that big a deal. I am pretty sure that most of the decent gas station air pumps have dryers in them, but you really don't know unless you ask, and even then, the clerk may not be aware either way.

As a driver who is totally anal about my psi, and who is constantly adjusting my psi in order to keep all four tires at the same psi, and who lives thirty-five miles from my primary dealer (nitrogen source), nitrogen is not a logical option. To properly replace either pure air or a mixture of pure air and nitrogen with nitrogen, the tire must be filled and drained with nitrogen several times. That seems like a pain in the *** to me. If I ran my car on tracks or owned an airplane, then yes, nitrogen would be my choice.

I've had Nitrogen in my 2017 since I got it in May of 2018, and I have not had to do anything to the tires at all. They still look full and firm and the tire pressure when I drive will start out low (not alarmingly low) but will rise as I'm driving. I love having it in my tires, especially in the cold weather having had the experiences in the past with losing pressure during the winter. I carry a portable air pump and I haven't used it since before my 7th Gen was traded.

Thank you all, very helpful feedback.

Pooling water was an extreme note, just to point out the possibility especially if you air up regularly in a humid condition without a dryer. That said, there is still a very high humidity rate going into the tire without a dryer, thus the air quality isn't pure which can have minor impact on tire overall performance.

I’ve got 5,000 miles on my ‘18 with nitrogen filled tires. My pressures range from 33 cold to 38 hot. nitrogen makes no difference in the fluctuation for my real world driving. What nitrogen does seem to help with is my pressures not dropping below 33. |

It's expensive, but 100% hydrogen is the best. Cancels out much of your unsprung weight. Major gains.

Please stop giving blatantly dangerous advice. Look up the flammability of hydrogen and report back if you still have questions. |

Lionel, this is all in fun. No one will find a source of hydrogen for car tires, much less finding some illigit to install it. :-)

How do you even know you have nitrogen in there? I have a bridge I wanna sell you.
|
Interesting that my 2019 Maxima and 2019 Honda Odyssey both have nitrogen-filled tires from the factory.
|
If I had a convenient, free or very cheap location near me then sure, I'll use nitrogen in all fours.
I'm indifferent to it, overall. |
I filled mine with sand so I can't get a flat. |
Just got mine topped off today, for the first time. One of them was at 26 psig, it's been very cold here. Did it at Costco in five minutes, at no cost, and I'm not even a member.

Think I might try helium in an attempt to counteract unsprung weight... :chrisman:

Hm. 50 lbs of Helium. Sounds to me like it weighs 50 lbs! Also I believe Helium is used as a leak detector as the molecule is very small and will find ways to leak out.

Spot on, coming from a chemical engineer. No, I would definitely not want He in my tires for precisely this reason. |
