Is getting nitrogen put in your car tires a good idea?

suggest because want money.

if know mixing nitrogen , air safe, , put air in tires low, nitrogen harmless (except our wallet).

if, when nitrogen-filled tires low, drive underinflated tires until can put more nitrogen in them, rather put air in them immediately, safer not put in nitrogen.

best whatever keep tires inflated. in theory, because nitrogen leaks slower, putting in nitrogen once, , topping them off air when needed (which won't often), marginally safer never using nitrogen. advantage slight, , not justify expense.

in practice, many drivers incorrectly think once have nitrogen in tires, have keep using nitrogen, wrong, drive on dangerously underinflated tires more nitrogen. driving on underinflated tires in order nitrogen, once, more dangerous using air time.

it suggested me when took car dealer bought service.
