$5 in maintenance sounds low. $5 a month in maintenance is $600 over 10 years, a new set of tires would cost around $600 and you should replace your tires before 10 years no matter the tread depth(1). I believe you are probably doing more maintenance to your car than new tires every 10years. You also can't just totally discount the initial cost of the vehicle like that as "free."
