Nitrogen In Tires

Is anyone using nitrogen in your tires? I'm told it is less prone to temperature effect and because the molecules are bigger, it won't seep out, like air can. One dealer even said he got a better ride in his truck..which might be stretching things a bit.

Do a search and you will find a multitude of post regarding this.

Normal air is already 78% nitrogen. I know people who used nitrogen and have gone back to regular air. They still had to keep the pressure checked and add when needed just as before and their tires did not last any longer according to them. So pay for 100% nitrogen or use free 78% nitrogen/air... think I will stick with free.

I have put it in all truck and trailer tires and see zero diff.. The pressure still goes up when warm. I don't know about life of the tires and won't for a long time. I hope.

All good points! I'll look into a bit more..but probably stay with air!
