Conspiracy Theory....Nitrogen Filled Tires ??

[robsmack01]

While doing paperwork for my Ram 1500 purchase I noticed some extra charges added on and asked about it. Turns out they had an extra sticker for add ons in the glove box. It was $99 for Nitrogen fill tires and $199 for Navigation. 2 things I didnt want or need. I didnt complain because other than that I was really happy with the purchase and i figure they gonna get you on something. A few nights later we had a cold front and ALL my tires lost 5-7 pounds of pressure lol

I would consider getting it for free at Costco, but considering how slowly my Duratracs lose air, I don't even bother. After 2-3 months, I think my tires lost about 1 psi.
