We have 2,021 Nissan Rogue. And it came with nitrogen in the tires well one of the tires needs to have air added to it is it going to hurt it to put air in it instead of

Putting regular air in a nitrogen tire will not harm the tire or gas inside the tire. (Atmospheric air is roughly 2/3 nitrogen). You will just have to drain and refill the tire with nitrogen to purge the oxygen you put in the tire to keep the deflation rate even with the other tires. (Tires loss pressure naturally as oxygen and nitrogen seep out through micro-fissures in the rubber. Nitrogen just seeps through slower thanks to the larger molecules.)

It will not hurt. When you are available swing by and and we can replace the air with nitrogen.
