Tires filled with Nitrogen
Hey everyone,
so I've always heard of nitrogen filled tires, some ppl say it's not worth it while some say they really liked it,
so I emptied the tires and filled them with Nitrogen for 2$ per tire.
the moment I got out from the shop I felt the "lightness" that I heard of,
first 2 turns the TRC kicked in, was really surprised.
but after 2 minutes of driving it felt just like it was before.
good thing is you can fill it with normal air if it leaked, and there is possible better fuel consumption(like I care).
just wanted to share,tires are OEM potenza's btw.

I really, really doubt you felt a difference. Remember, "air" is 79% nitrogen. Nitrogen just isn't as affected by temperatures as much as regular air. Not that it makes any difference unless you're tracking your car all the time.
FWIW, my tires are all filled with nitrogen. Not by choice, it's just the tire shop I use only uses nitrogen. It made no difference that I can discern.

of course you wouldn't notice a difference, cuz you haven't tried the normal air first to compare.
I've filled it after 40000km of driving on normal air.

As noted, your tires were -already- about 78% filled with nitrogen before you spent $2/tire...at which point it was about 95% nitrogen.
Consumer Reports tested the "less leaking" claim and found Nitrogen shows a real, but quite small, improvement over normal air. (Over a full year the nitrogen tires lost 1.3 lbs less pressure than the air filled ones).

Um no, the tires don't come from the factory with nitrogen. So when I had the tires swapped, they filled them with nitrogen. Of course no difference.
I'm amazed that people think you could get better fuel consumption too. People will believe anything. I rate nitrogen in the tires up there with those tornado intake things people use.

The biggest difference isn't the nitrogen, its the lack of humidity. Dry air and dry nitrogen are almost indistinguishable. Humid air vs. dry nitrogen will have a very big difference in performance at the track because the dry nitrogen filled tire will experience far less temperature instability and pressure rise. Jet aircraft use dry nitrogen for tires, landing gear struts, and gas filled hydraulic accumulators because of the temperature extremes they experience in normal operation.
For the street, there's no discernible difference.

nitro for car tires is only useful if u track ur car.
plain and simple.
learned that from johan van overbeek when he compared the Porsche GT3 RS to his GT3 racer in ALMS
What OP felt was prolly thin layer of grease/oil he picked up off the floor of the shop he visited? after a few minutes it'll rub off, tire temps pick up and u get better grip.
or total placebo effect

Our cars are not Formula 1 machines that operate at critical thresholds. I filled my tires up in early September to spec. I checked them last week and each tire had lost six pounds, which is a rate of 1.5 psi per month. Big deal. We should be checking them monthly anyway at which time we can top them up. Nitrogen is one of those things that won't hurt, but completely unnecessary. It's a nice little profit center for those that peddle it. If you think your car drives better than go ahead, but it's all in your head.

I agree with above posters about monthly tire pressure checks. A better investment for most is a small compressor to keep in the garage. It's always best and easier to check tire pressure in the comfort of your garage, first thing before the car is driven (so that you get true "cold" measurements).
