Dealership didn't check pressure and nitrogen fill in tires is low on entire right side. Should I take it to them and have them fill with nitrogen or just fill with normal air.
Thanks!

Air can be added, but use nitrogen if it is available, different elemental densities and rates of expansion. Nitrogen maintain longer over the life of the fill.

okay the atmosphere what we breath the air that gets pumped in yer tires all that is already 86 percent nitrogen and if they fill yer tires with nitrogen at the tire shop its like 98 percent nitrogen so having an extra 10 to 15 percent o2 in yer tires doesnt make much difference this whole trend idea of filling yer tires with nitrogen is so dumb because guess what youve been filling them with nitrogen already if anyone is out there charging extra for filling the tires with nitrogen do not take it just go with the leaner 86 percent stuff lol

While what ccapeheart says is essentially true, it overlooks other factors. Nitrogen doesn't expand like normal breathable air. That means that your tires won't vary in pressure as much between cold and hot temperatures. We learned this trick on stock cars 30 years ago.

All tires leak. Nitrogen doesn't permeate the tire carcass like normal breathable air does, so over time your tires won't loose a couple of pounds of pressure. I use this on my vintage Corvette to keep the tires at pressure during storage.

Oxygen is reactive, nitrogen is not. I believe this helps keep tires from deteriorating over time. Even though the outside of the tire is exposed to normal air, the inside is not with nitrogen.

sorry didnt mean to sound like such a smart ass
they also did a study that covered 5 or 6 catagories for example you were saying losing pressure the benifit was very miniscule in all catagories because even the pure nitrogen stuff is only 93 percent i found out with some research so your really only getting rid of 14 or 15 percent o2 i guess if its free to put it in there sure but i definatly wouldpay anything for it like i heard some dealer s tached on 70 bucks
