I just got my first truck with a tire pressure system. The first cold night and the light is on and my tire pressure is low. I read that nitrogen helps with this problem. Anybody use nitrogen instead of air? Is it worth the price?


Thanks in advance.

I Do In Both My Vehicles & I Think It Helps In Cold Weather.:-)

It may. Remember that regular air is like 85% nitrogen anyways. Just keep an eye on the pressure, and you are all set.

The nitrogen thing is like snake oil to me. But I have an air compressor in the garage, and can check pressure/top off the tires every night if I felt like it. Especially for the exhorbitant price they charge for it. If they'd do it for free, I may try it.

Consumer Reports: "Overall, consumers can use nitrogen and might enjoy the slight improvement in air retention provided, but it's not a substitute for regular inflation checks."

I just use air!

If you are a NASCAR driver you need nitrogen. Otherwise... no!!

I Have A New Acura; The Dealer Recommended Nitrogen Because Several People Were Having The Tire Pressure Warning Going Off When The Weather Turned Colder. My Tires Stay @ 35 PSI & Have For The Last 6 Months.

:-) your tires dont get hot enough to worry about it. Just do regular pressure checks and all will be good.

Your tire pressure can have some pretty significant changes throughout the day. In the fall on cold mornings, my Z will have read out at 29 psi in the tires when its 35 degrees, then later in the day when its 70 and sunny, the tires will be 34-35 psi. In the winter, I just fill the tires and check the pressure when its in the mid 20's and i'm good to go

Also, I may be off here, but don't your tires warm up considerably once you're driving? Even if the reading is off in the morning before you get started, I would think that you'd be good to by the time you hit the highway:-)

That may be the answer for my mother's accord although the tire pressure light wouldn't even go off while I was driving it down in FL.

Air is just under 79% nitrogen. I get the warning on the first cold day of the year and put a little air back in and all is good until the summer ( 6 months typically) which is about the normal leak rate for air on most tires. Nitrogen is slower in most cases but a lot more expensive to refill.

You will gain maybe 2 - 3 psi if you drive for a bit, but that's the most I've noticed even in the summer.

Great Article, Jay!:-)

If someone wants me to pay it forward with a Pif other than cigars, I can send you a Nitrogen Bomb. :-)

Is that anything like a :-) ?
