I put helium in my tires, reduces unsprung weight.
Yes air is about 78% nitrogen, and unless the nitrogen filling place is flushing all the air out of your tires and replacing it, I doubt you would get more than 90% pure nitrogen in your tires. If that 12% is worth it to you then by all means do it, if not... then I don't think its really a big deal.
I'll probably get nitrogen in mine because the place I buy my tires from does free nitrogen inflation.
