I just got my Falken rt-615's mounted and the place asked me if I wanted my tires inflated with Nitrogen. I didnt do it but can always go back. Supposedly tire inflation stays more constant and the tires do not wear as fast because they wont heat up as much, which is fine with me because I dont track the car. Just wondering if anybody else has experience with this?

 

I fill my rally tires with nitrogen, basically the tire pressure stay constant. It only makes a difference if small pressure changes will cause a negative performance effect. I wouldn't pay extra for it for street tires.

 

What about tire wear? Will it help?

 

Approximately 78-80% of the air is made up of Nitrogen. Sorry but it's more of a marketing gimmic to me ...

 

The main point of nitrogen in a street tire is that you don't have those extras like water and oxygen to rot your tires from the inside, and you don't loose as much pressure between fills.
