I voted its a good idea, if its $20-30 bucks, try it out. if its more, forget it. like I said a friend of mine has never had to touch his tires in 4 or 5 years of owning the car, and as the other guy mentioned nitrogen is said to be less effected by the seasons and temperature changes.

I wouldnt go out of your way to try it, but when i just had my tires mounted, had the guys tried to sell it to me, I probably would had.

The tires that came on my truck stock are filled with nitrogen. If the dealer/ dodge did that, there has to be a reason for it

 

last night our temps fell to around 16. When I statred the truck this morning my tire presure screen lit up with all four tires showing 29 lbs. They were 38 lbs yesterday. I drove it a few miles and no change. They are nitrogen filled. Do I have a problem with the system or does cold air affect the tires that much. I thought it wasn't supposed to.

 

Might as well burn your money

 

I have a buddy who owns a couple of tire/repair shops in south Georgia. He offers nitrogen and whilst fishing with him one day I asked if I should have him put nitrogen in my tires and he just laughed and said "yeah, and I got a bridge up in Brooklyn I'll sell you too". That was enough for me...

 

Sounds like you may need some Nitrogen STABILIZER additive. That'll be an additional $49.95 every 3,000 miles.

 

Sounds like something is wrong with your setup. Your tires aren't supposed to drop that much, if at all. I've known nitro tires in temps below 0, and they didn't change at all. I doubt all four of your tires are leaking, so there is either something wrong with your pressure monitors or the people that filled your tires didn't do it right.

 

Just from what I have seen, Nitrogen is a cool "trick" to use, but it's not something I would pay for.

In Missouri, our temperatures can be 1*F today and 40*F tomorrow OR 40*F today and 75*F tomorrow. We have some wicked temperature changes across the board.

As we all know, oxygen and nitrogen will expand and contract with the change in temperatures. Nitrogen is just affected by it much much less when it is 100% nitrogen. When I got my truck, the tires were Nitrogen filled all the way into November when I had the wheels changed. In that time, we had a few days where there was a 30* or more temperature swing and I never once saw my tire pressures change by more than 1PSI.

When I buy new tires, I might pay a little extra for the Nitrogen just for the lack of pressure swings, but not $10 a wheel. More like $20 for the whole deal.

I have seen people also claim that the Nitrogen atom is larger than an Oxygen atom keeping the leakdown inside the tire to a minimum... While this is true, I have yet to see evidence where it actually holds water. I mean, I only get flats or go low when I do indeed have a leak somewhere.

 

It won't burn in a nitrogen atmosphere.

 

I agree $20 bucks for all would be ok $40's a bit much. I do keep nit in mine. My last car I had just oxy in the tires (in Louisiana) and would notice a change of up to 4lb +- depending on weather and how fast i was going at the time >
Now in Oklahoma my new Dodge has nit in them and only notice at most a 1lb+- which is nice and I havent ever had to refill them yet. Made friends with my service guy so I get that for free.....with that said $40 seems a bit much to have to keep up but try it one time and see how you like it and how long it lasts you.
