well if your an engineer, did you read the above scientific DATA that I posted from an article, that clearly proved the point of it being better ?

I did mean fill back up at the con with air , then let it out at home and refill with N2, that is kinda like saying well I better not put this old dirty water from the stream in my radiator , because it's not as good as Distilled, so I'll just run it with out water until I can get to the store to buy some Distilled.....so you get home , let the "Air " out , refill with Nitrogen and because it's heavier than air , there's no need to purge , it'll dry the water after a mile or so of driving.

Well I tell you , Your an engineer that lives in one of the most expensive areas of the country and you can't afford 8 bucks.......come on .....SS one else, it's just you like to argue for the sake of argueing , I guess , there are several articles abouve that prove that nitrogen is better than air, but I guess if your an engineer , your probably like the ones at LLNL or Sandia, that want a thousand or so articles proving it. Why don't you conduct a study , as an engineer and document it and publish it in the doctrines of modern thought on the subject . Have your company or the government pay for it , I'm sure as an engineer , you've solicited funds to governmental agencies for "Studies" maybe through the DOE, even, Huh ???
otherwise, if you don't agree .... move on !!!

 

35 x 12.5 x 15 on 8" x 15 Black Rock Crawler steel rims

 

I know that they would probably be better on a 10 inch , but they'll peel less with low pressure with a 8"

 

Data means numbers, not an interpretation by some guy driving an RV. And again, I said YOUR truck, not an RV. The articles don't prove anything about your truck (or any common passenger vehicle). And of course the costco guy is going to say nitrogen is better. Costco advertises nitrogen so they can get more customers.

And I want to move out of state soon. It's way too expensive around here. $300k for a 1-2 bedroom condo and no garage...no way. My wife and I are thinking of moving in with another couple to save money. So yes, $8 is an opportunity cost I'm unwilling to spend.

It takes two to argue. I like to have indepth debates with other people who like to learn through debates. It doesn't seem like you want to continue this debate, so I'll drop the nitrogen subject. If you'd like to continue this debate, let's go to PMs.

 

Ok, one last thing and only because it's funny...

I just thought of something. Since costco uses N2 and they're usually pretty good with service, you could buy your next tires from them and then just go back and have them refill the tires for free everytime you go wheeling!

 

I don't know how I missed this thread...I laughed so hard reading through it. Sigh...I'll try and keep my wise-ace comments to myself though...

When I saw the thread, I thought it meant the coffee kind of Equal, too.

 

I suppose if money is no object, go for it. But here's my reasoning for calling it "bunk":

1) Since I typically air down from about 35 psi to 28 psi everytime it snows (about 1/week lately), having to air back up with N2 sounds out of reach for me.

2) I typically put about 25,000 miles/year or more on my tires so after 2-2 1/2 years I'm replacing them. Any deterioration is going to be on the outside from UV, mositure and the rest of the elements as compared to the inside of the tire in that time period so filling with N2 will have no bearing on how long my tires last. External impact over time is the critical path.

3) I'm fanatical about maintaining my tire pressure and typically check and adjust it as needed about once a week or more. N2 or not, I'd be maintaining them that way which the average Joe doesn't do.

4) N2 follows the temperature/pressure laws no different than any other gas, so you still have to adjust your tire pressure based on seasonal temperature changes regardless if you use air or N2.

As I said, it's my reasoning why I wouldn't go running off to use N2. I think the Equal idea is great but I'm still not convinced that it's right for me or that N2 is worthwhile for the vast majority of rigs. So if you don't agree, get over it and move on (as someone keeps telling everyone).

 

bump to read later

 

Real mature. I bought my K5 because Toyota didnt make a vehicle that did what i needed one to do, and sold my '83 trail rig recently due to back problems. And im not going anywere, get used to me.

If you are filling your tires with air from a gas station, yeah, maybee it will stay drier and keep the equal from clumping. I dont, i have a filter that i drain once a month on my compressor that keeps me from filling my tires with water, and i dont air up at gas stations. Any leak you have that is noticeable, is not caused by air leaking through the rubber and nitrogen will not fix it. If you run your tires for 10 years and 100K miles, it may be benneficial. I have cut appart more than my fair share of tires over 30 years old, and have yet to see steel belts rust because of moisture bleeding through the tire.

Also, it will not "dry" the tire if you fill it with moist air at any point. It has no absorbtion propertys and will simply mix with the water vapor that is already in the tire, just like it does in our atmosphere.


Now, lets put some math to all this, since you will still argue what i just said. Lets say you drive 12K miles a year. You spend $96 per year on N2, and your tires cost an even $200 a piece. Lets say that the N2 does help, and you get another 1K miles out of your tires becaues of it. Thats an extra month worth of driving on the same set, seems reasonable. To make this easier, we will say that without N2 you will get 36000 miles out of your tires,which is pretty average for an off road tire, and with it you get 37000. At $200 a piece and an even 36000 mile lifespan, you are paying ~$.005556 per mile. At that cost, you are saving $22.22 by driving that set of 4 tires an extra 1000 miles, and you are paying $288 to do it. Does this actually make sense to you? You just spent $265.78, to spend the same $800, one month later. For you to break even, N2 all by itself would have to make your tires last an extra 13K miles.

Now, in an RV or semi that sees 50-60K miles while airing up once or twice and is a more road friendly tire, getting that extra 2-3K miles for $12-24 is potentially worth it, espeically with how much tires that size and load capacity cost.

And on to your "if you dont agree, move on", that is how missinformation spreads and company's like costco thrive on it, because somebody else on the internet said that N2 is better and nobody argued it. Does it potentially have a few benefits, yes. Are you going to see any of them? Maybee, but most likely not. Are you going to end up behind in the long run with the expense? You sure are. But hey, its not my money.

At this point, if you want to run it, its up to you, its your money and you can spend it as you like. If you can get it for free, great, then by all means do it. But to spend almost $300 to save less than $25 seems pretty silly.

 

Gee I guess I can't have my opinion here without all the P.O.S. copping an attitude.

whatever

 

No, you are perfectly entitled to your opinion. But the point of a forum is not to just accept everything you read as fact just because somebody says so. Like i said, you may see other benefits, but to spend money trying to save money, only to end up behind by a couple hundred dollar in the end, doesnt make sense to me.

Think about it, that ~$265 could buy yourself a front locker, a nice date for wife/girlfriend, or even centramatics to more effectively balance you tires, which, IMO, would be a better investment than N2. I just see other places to better spend the money, than on a gimmick.

Sorry if i offended you.

 

I hear ya man. I work for GM but I don't think that entitles me to leave the forum either. I drive a Toyota so I would figure IF there was a qualification for this forum that would be it, but I dont believe there is a rule for you to own a Toy.

 

Hey I own a old Husquavarna, what do you think about the right foot crossover shift assembly kit I've seen advertised for us old Husky owners ?

 

What do you think about the new castmaster for this springs Sierra Trout Derby ?

 

I heard that the Macks' are hitting at 40 ft at Union valley res, do you have experience with these ?

 

are you experienced with the "Pendulum Cast ? I've tried it for Leoprds at Bolinas lagoon with little luck, whats your experience ?

 

so when adjusting the slack in my sails on my 18 ft hobie cat, How should I do that in a 23 knot headwind, with a 15 knot current ?

 

You don't seem to get it. Maybe you'd be happier at pirate.

 

I 'm looking for Must II IFS for my chevy / dodge hotrod I'm building, where can I get one locally ?
