Alright heres the run down. Bought new 33x12.5x15 KM2's, $733 shipped. $65 to mont and balance, $20 to put nitrogen in tires, Now i got one outta round. Here at local Ford dealer which is awsome!! to have all 4 roadforce balanced to make sure the tire i think is outta round is and to check others. called Discount Tires Direct and they already sent me a new tire to replace it with and told me if had anymore issues with others they would send new ones out and there were no questions asked!!. SO here @ the dealer it's $35.00 for roadforce balance and another $12.50 to mount and balance new one, then I gotta take it back to the other tire shop to get the nitrogen put back in for FREE. so heres the run down.

tires - $733
M&B - $65
Nitro - $20
DLR - $55
-------------
Total $873

end result PRICELESS for playin the MUD!!!

OOPS!! just realized this was wrong thread thought i was in General Diss.

 

Im sorry to tell you that you wasted $20 putting nirtogen in them. When I worked at Costco we put nitrogen in them for free. It gives you no real benifits, well atleast not $20 worth of benifit.

Heres the reasoning:

1. nitrogen leaks "slower" you lose 1 PSI ever 3 months as compaired to 1 PSI per month with regular air.
2. they claime it doesnt change pessure as much with the change in temp. That is true...kindof. With air you lose 1 PSI for every 9* the temp drops. With nitro you drop 1 PSI with every 7* drop in temp.

The thinig is you should still be checking your tire pressure at least twice a month (or everytime you fill up) so either way you will have to check them.

3. the air you breath is 78% Nitrogen, 21% Oxygen, and 1% other stuff. The best nitrogen seperating machines get 96% Nitrogen 4% other stuff. Even if you do fill your tires with Oxygen you still have mostly nitro.

If anyone ever tells you that you can put regular air in with nitrogen, laugh at them and tell the to do it anyways. If you top off with regular air it will not effect your precentages at all. It WILL NOT damage your tires in any way, jiffy lube is famous for saying that it will damage your tires.

 

Yeah the whole reason for the Nitrogen thing is the Nitro molecule is larger than the oxygen molecule. I feel sorry for you that you paid $20 for a larger molecule. Most I ever pay for air is $1.50 at gas stations.

 

I always find a gas station that has free air....I can't justify paying for air!

 

I never used nitrogen because I think it is mostly a joke. I still can't see how anyone would actually pay to put it in their tires.
Plus when I had my ranger and sport trac I would normally air down when I went offroad anyway.

No matter, that is a great price on the tires! I hate having 18" wheels!!

 

Nitrogen also helps the tire stay cooler. Big trucks run it with benenfis

 

DING DING DING WE HAVE A WINNER!!!!

Someone had a very good marketing idea and it took off. The only reason we did it at costco was to keep up with the competition.

 

$ 873 ?? Sounds steep to me....I recently bought 4 standard 225/70R 15 tires, not for off roading but for regular street driving and they cost me $444 mounted, balanced and tax out the door.

You're paying a lot to play in the mud.

 

Different strokes for differnt folks, man. If you wanna play you gotta pay. If you wanna think about it a 1989 honda civic would have gotten you around town just the same as that ranger, but you wanted to have the truck for the utility.

And plus you got goodyears.....I wouldnt be proud of that. Goodyear....Good for a year.

 

lol...my Good Year's come with a 50,000 mile warranty, and they are nice and quiet riding on the highway, and they didn't come out of round.

I wouldn't be too proud of running my nice shiny Ranger thru the mud on purpose.

A 1989 Honda Civic ?? hahaha I had a 1992 Ford Tempo that got me around for many years, but getting in and out of it was hard on my back....that's why I got the Ranger to get me around town, I can get in and out of it with no problems. I don't want it lifted because then I'd have to climb into it. I don't want that at all. That's what happens when you get old like me. hahahaha

 

your talking apples and oranges here, i have over 6 inches of lift, no way will i run 225/70R tires and i doubt if anyone that was overly worried about tire prices would lift there trucks in the first place. thats a killer deal for those KM2's. i would like to see pics of them on there!!

 

i used to work there, they just want to cover there asses like any other automotive place. and yes we were told to not touch nitrofilled tires.

 

You have to pay to use compressed air?

Man, I feel bad for you.

Hoz, sounds like you got a pretty good deal. I paid $800 just for my tires, mounted, balanced. And that's a 285/75-16, which is STOCK for my Dadge.

Although, I did only pay like, $300 for my Rangers, but that's 235/75-15's lol.

 

got to love your tire problems lol..

 

We need pictures of your new tires!

 

Well the nitrogen thing i can tell a difference and thats all that matters to me and it was worth the $20 for me but then again thats my opinion. Turned out the tire was OK they just rotated it 180* on the rim and its SOOOOOOOO much better now!! so it only wound up costin me $36 for the roadforce balance and went and had the nitrogen refilled for free whick i get for LIFE!! Thanks for the comment and opinins!! Greatly appreciated!!

 

NEWS FLASH

1.) Anhydrous air is over 75% nitrogen. The rest is oxygen and inert gasses (such as CO2, argon, etc...). Oxygen is only a tad bit smaller than nitrogen. I dont think the leak difference is anywhere near that much.

2.) All gasses expand and contract at relatively the same rate as far as we are concerned. When you start getting into super cold temperatures this isn't the truth but your tires will never be cold enough for this to matter.

You fill tire with nitrogen because it is anhydrous. Anhydrous air is hard to come by, and the air coming out of your shop compressor most certainly isn't anhydrous.

Truth be told, CO2 would be the best cheap gas to fill your tires with.

 

Then if you put co2 in your tires you can get some money from al gore for taking away some pollution!

 

LOL!! already have but incase you haven't seen'em here a ***** pic



Well seems like you know your gases!! But then again like i said i appreciate the knowledge and opinions but its done and i'd do it again. I do notice a difference and i had them originally filled with air. but appreciate the lookin out bro!!

 

Oh I'm all for nitrogen in tires, I was just clearing up the misconception as to why you put nitrogen in your tires. :)

 

LOL!! Well cool then you lost me there in those big words and stopped readin!!

 

Your 4 tires cost as much as my two rear tires mounted : (...so I say good deal.

 

Yep you either get it free (with a purchase of gasoline) or pay at the compressor. It used to be free. It's rare to find a gasoline station that has Air, it's even rarer to get the air for free now.

 

All the air pumps at gas stations around here range from $0.25 - $1.00. All the proceeds goes towards the local fire stations in the area for different charties. At leaste the money is going towards a good cause and NOT the gas stations.

But I use my air compressor in the garage. It's free.

 

Back home we have a chain of gas stations called S&S that sell BP or Shell gasoline. It's owned by a local and you'll only find them in the north florida area. Most of them have free air and the compressor adjusts the pressure in your tires for you! Just set the pressure you want on the pump station and hook the pump up to your tires. If you're over inflated it will let air out for you, too!

Think I would find that in Tampa? You're out of your mind. I have to pay $0.75 ever moth or so to air my tires up and the pumps dont even have a pressure gauge on them, let alone a nifty mechanism that takes all of the guess work out of it for me.
