So, for the average car/bike owner…nitrogen or air?

If you’re a slacker when it comes to checking tire pressures (or using valve stem caps), then nitrogen may be just the thing for you; decide for yourself whether the time you save in pressure-checking justifies the extra cost of using nitrogen.  But if you’re as vigilant as you ought to be about vehicle maintenance/inspection, then here’s what you can expect:

In fact, according to this article, “Michelin officials recommend nitrogen only for tires used ‘in a high risk environment and/or when the user wants to reduce the consequences of a potential abnormal overheating of the tire-wheel assembly (for example in some aircraft applications),’ according to a company statement.”  IOW, the average Joe should save his hard-earned money and just inflate his tires with air.
