Anyone have experience of this / know the costs involved in inflating with nitrogen.
I understand Nitrofill has dealers all over the country.
Thanks

Yes, it's about $75-$100 to get all four nitrogen filled. CO2 is the other option.

But have heard rumors of $3-$10 per tire.

I like it during winter hibernation. I take the Porsches over to a local Cassidy Tire shop, they over inflate them for me to about 58 PSI and I give the kid that helps me $20. He is happy, I am happy. Then I drive the 1 mile home very slowly!

I'll bet 58 psi adds a whole new dimension to the concept of "skittish!"

No HTwo O

LOL! Driving much to slow to worry about "skittish". It's the railroad crossing that worries me.

Not sure about near you guys bet here in NJ Costco fills tires with nitrogen for free and will also top ou up for free if you get your tires from them. I have ahd them put tires on maby cars and they do a very nice job.

Yep, Costco out here in Marin also uses Nitrogen to fill. Standard, no extra charge.

I understand the pitch for why Nitrogen is a good fill for tires but given that regular old air is 78% nitrogen does going to 100% really make that big a difference - especially on a street car? Also consider that to get 100% Nitrogen you'd need to pull a vacuum in the tire before filling, which I suspect never happens (except maybe in F1), so even with a "full" fill you'll still have some O2 in there. I guess if Costco will put it in for free that's fine but IMHO it seems hardly worth the trouble.

I suppose you'd have a tough time getting to 100% Nitrogen, but when installing new tires, they could just hold the bead off for a few seconds until the Ni pushes out most of the regular air, before setting the bead... then you'd be pretty close to 100%.
I agree that it's not worth spending any xtra $$ for it.

Hype and a way for tire dealers to make more money. we do it on airplanes where we are inflating to 180-200 psi. At 35-40 you're gaining about 1% benifit.

Some further research on other forums indicate the cost of a nitro-fill ranges from free at Costco to $30/tire or $90 for four - take yer pick.......

The NitroFill website have claims from better road holding to increased MPG, etc. etc..

Other forum comments were such as this :-
I would suspect that after running over the first nail, the nitrogen user would switch back to plain, old air and consider himself the better off for it.

Tanked nitrogen can be had from welder's supply outfits such as AIRCO. They also have helium, which, if you put it in your tires, will save you money by making your car lighter, thus using less gasoline, and hydrogen in case you want to torch the heap for the insurance payoff and/or dispose of an embarrassing corpse.

In brief, nitrogen looks good in print and NASCAR loves it, but it's more trouble than it's worth for thee & me. It's best left to special applications.

I thought a rennlister may have tried and had actual knowledge of nitrogen filled tires.

When we bought our new Outback, they filled the tires with nitrogen. I was told that it's necessary because of the tire pressure monitoring system (TPMS). Supposedly, I was told, the tires hold the air pressure better during cold/hot climate changes and are less prone to leaking. Not sure if I truly believe that, but I have a friend that has a TPMS and he has to add air every winter and if he doesn't, the dash "warning" lite gets very annoying. I think the nitrogen (for the public) came about when most new cars come equipped with TPMS. Anyway, it's free for us at the dealership where we bought the vehicle from. Getting back to Porsche, I declined getting the TPMS valve stems and system when I went to have tires installed on my new wheels. I may be old school, but I can check the air pressure myself - thank you, I do not want some device telling me when to do it.

Free nitrogen at your Subaru dealership is good.
I have to be content with knowing that there is only 78% nitrogen in my tires!

My opinion is it's a complete waste of time for a street driven car. There's a lot of snake oil being sold out there. Professional racing is a different story, but I think you should save your money and your sanity and stick to good ol' air. Air works great.

100 % agree with Falcondrivr, A/C benefit from it because of the high PSI's, but auto's with 30-50 psi don't really see a benefit unless some sort of purge systems is utilized. MONEY Maker for the stealerships!
