Stupid question about tires

gimmick

unless you are racing and having issues, so I doubt you are.. it would be better to use a stapler and tack a note to your forehead to not make life so complicated than to put nitrogen in tires...

+1. this question or one like it surfaces from time to time. bob is spot on. if the seller is using nitrogen as a selling point or to charge extra then i'd walk away.

Pure nitrogen is more stable in pressure vs temperature.
Other wise it's 100% compatible with the standard 78% nitrogen mix that we all breathe.
Bottom line it's not a bad thing, nor is it worth any $ or favorable consideration in your purchase decision.

The cynical and skeptical side of me would just presume that the dealer bought a bag full of green caps and is spending $0.67 per RV to upsell with nitrogen in the tires....

You are breathing 78% nitrogen right now and, yes, it mixes with...air.
