I purchased 8 Michelin's at Jacksonville Prevost the other day. They are in the process of installing a nitrogen service there.
The Marathon Florida location is considering installing one as well. When you dump nearly $7K in new thread adding a few $100 doesn't seem like too much for all 8. My concern was when I needed to top off the tires, this will not be an easy process finding Nitrogen, plus there is no reason in the world it has to be so expensive. Get the price down and more people will get onboard. The machine costs $5k, how much does a really good balancing machine cost. Price it right and all trucks and RV's will fill up on it.
