Why Nitrogen

We fill ALL of our New and Preowned vehicles’ tires, at a one-time nominal cost of $39.95, with PurigeN98, before any of our vehicles are offered for sale!!, AND we refill them for free, for lifetime of the vehicle*!!

We offer high purity Nitrogen! This helps increase the life of your tires, maximizes your fuel economy and reduces the pressure swings in your tires.

Under-Inflated tires cause increased tire wear and reduce your fuel economy. High Purity Nitrogen is the best way to keep your tires properly inflated for maximum life and fuel economy.
