save your money I found the best thing water, just fill them up

 

The last time I got new tires for my vehicle, the tire dealer inflated my new tires with nitrogen for "free". Once a month I could stop by, show my receipt and have my tire pressures checked and filled with nitrogen if needed. The valve stem caps had a green dot in the center, which he claimed they used to indicate that the tires were filled with nitrogen. Later I found out that roaming bands of nitrogen thieves were stealing the nitrogen out of peoples' tires to re-sell in back alleys. These thieves used the green dots on the valve stems to know which tires had nitrogren in them and which didn't. So if you do get nitrogen in your tires and they use the caps with the green dots, you might want to replace them with regular black caps to keep from finding the nitrogen stolen from your tires.
























It's amazing the BS that some people will believe.

 

Great story, Russgriz! Ranks up there with the snakes coming out of the toilet bowl and biting butts!

 

I think the nitrogen thief's will just steal the whole car instead of just the air in the tires. Ronnie

 

I've always thought the same thing as well...

And another thing. If you're following the manufacturer's recommendation for PSI from the door sticker, how much do you have to add when running that extra 20% nitrogen? The door sticker is the cold PSI, when using normal air, which will increase in pressure from heat. Having this wonder air that isn't going to increase as they heat up, you'll need to up the psi a few pounds. I'll stick to the stock air and not void my warranty.
