Sorry. I was overcome.

I think that the speed limit is 120 and on some of Coquihalla Highway it's 140. I just go a little over it as that car really loves the speed and the rpms

I'm running 90% nitrogen and 10% air and that seems to work well with the tires.
As for nitrogen for the trailer I'd definitely do it as there's no built in ABS, temp gauge nor air pressure sensors like found on a car.
For safety, tire wear and blowouts nitrogen is a pretty cheap way to go

I run 78% N2, 21% O2 and 1% whatever. A little electricity and mechanicals to compress and in it goes. I drive/ride/fly the local Sierra Nevada with gusto without busto. So far, so good.

No busto. I love it!! I've been at it for 37 years and no busto yet. Doesn't mean it's not going to happen. ....
My biggest problem is that as I get older I get bolder!

It's pretty much a solution looking for a problem. Also, if your tires are correctly aired when cold, the pressure stability argument is weak at best as the tire manufacturers recommended pressures account for the pressure increases when the tire heats up.

PerryB · 03-26-2016, 04:14 PM

Bob , I'd love to argue with you, but first you'd have to be wrong.

With nitrogen your pressure stays the same hot or cold and that's the whole purpose of using it. It's fail safe and as I stated with a trailer you have no idea what the pressure is while towing as it'll go up and down as you drive which will cause tire wear and blow outs

Try it and see if you haven't already

I have followed the nitrogen/air argument for years. I have stayed with common air from our compressor, but it still interests me. This website has a fairly good comparison/tests and is worth a read, although a little long.
https://powertank.com/truth.or.hype/
I am reprinting their conclusion here.
"Conclusion of High Pressure Gas Test:
At the higher tire pressure commonly seen in RV tires we took the gases through a temperature range of 154ºF (-20ºF up to 134ºF). Our start pressure was 80 PSI @ -20ºF and over the 154ºF temperature increase we saw the gas pressures all increase virtually the same amount to within 2 PSI of each other. In the end, the N2 and "air" test samples topped at 108 PSI while the CO2 sample topped out at 110 PSI. Note that the pressure changes that we saw in our bottles are the same as what you'd experience in your big RV tires despite the difference in volume. What does this mean? No matter which of these gases is in your RV tires, your handling, performance and tire wear will be the same."

Thank you. Besides, those green valve stem caps are major ugly.

No it doesn't. That's a major myth to sell it. It builds pressure and drops pressure just like the stuff out of the had station air hose....just not as much. I worked in a dealer that sold it and when the cold came had to top off air. The machine manual said and I quote "in colder weather bump air pressure 2 to 4 lbs to prevent tpms lite from coming on..." same thing we did with the free stuff. On race cars the air pressure builds as tire temp goes up too....

Me too and I haven't had any issues from it either.....

With the A 7 I might gain a 1/4 lb while running it hard and the pressure stays the same with all the tires. If I just ran straight air the pressure on all 4 would be all over the map and that's not too safe in my mind

As for getting air from the local station you must keep in mind that they don't take care of their tanks and you'll end up with oil and water in your tires.
I've read the posts here and it seems that the experts are great at pulling up stats while surfing the interweb but the true experiences come from people that actually use nitrogen.
Like why take chances of having your tire pressure unequal on all 4 when you don't have to? Like I've said before it's cheap insurance

Desert185 · 03-28-2016, 09:40 PM

Personally, I use my own air with a water separator/trap. Never from a station. No water or oil in my tires. To each his own. Eh?

Nope. 120 Max. Not to say I haven't done 150, but it's 120 max.

The thing I don't get about Nitrogen, is the number of places that won't charge for it. I know it's a marketing gimmick, but Costco doesn't charge extra for it.

I want to see that audi go 200 kilometers per second without it being tossed from a c130.

lithium with decompose (burn) in a nitrogen atmosphere

That didn't make any sense

Why would I chuck it out of a water bomber to go 200 kms? I bought it new, drove it for the break in period then send it to a sports shop and had them trick it out. The car is like a rocket that's built for speed. It's a great stress reliever

But staying on topic; you can talk to 10 different shops about nitrogen and you'll get 10 different answers. Nitrogen has great advantages in certain applications like my car but yet the same tire shop said that it's a waste of money to use it for my truck.
They only reason that I say it's great for a trailer is that all four tires will keep the same pressure as the air temp goes up and down.

WELL STEVE YOU CAN MONITOR TEMP AND PRESSURE IN YOUR TRAILER TIRES. I HAVE BEEN USING THE STUFF THE THAT WE BREATHE FOR YEAARS NEVER HAD A PROBLEM WITH IT. AND I AGREE WITH BOB. JUST MY 2 CENTS ... SORRY ABOUT THE CAPS I AINT YELLIN

Yes I know this as I have the monitoring system on all 6 tires on my truck
