Ok, my daughter is about to buy a new to her 08 honda civic. They gave us this big spiele on nitrogen vs air in tires. Now it is 379 to do it, supposed to give u better mileage and less wear on tires and this amount also covers 5 years, so if she blows a tire, they replace it. I have googled and read, but what I have read is 50/50 on whether it is worth the initial cost...wondering of any of you have any experience with the nitrogen or know anything you can tell us! Can't decide if it is money worth her spending or not...thanks.
