The quick and easy answer is if you have to pay for it then absolutely not. The benefits of having nitrogen in your tires are true but to such a small degree it is highly unlikely that you will notice any of them. The reason for this is because the air we all breath, and that is probably in your tires right now is made up of 78% nitrogen already. So it's not a matter of comparing nitrogen to oxygen, it is comparing 78% nitrogen to almost 100%.
