Hey all, I was wondering if anyone out there has filled their tires with nitrogen on their Suburban/Yukon XL ?? I work for a new Acura dealer and they have some mighty big claims about the benefits. Their claims are as follows- The nitrogen filled tires maintain air pressure better with much less fluxuation resulting in TPMS lights going off, Nitrogen keeps the tires 20% cooler, Nitrogen filled tires use less fuel, they extend the life of the tires, they improve ride and performance, reduces tire failure by as much as 80%, and increase gas mileage by as much as 2-3 miles per gallon. I'm wondering how much of this is fact or fiction ? Any feedback would be appreciated. Thanks all.
