How often should car tires be changed or have air put in?
 

How often should car tires be changed or have air put in, if usage is for a sedan or wagon and someone that works 9-5 5 days a week (15 miles each time)or less than that, if it really makes a difference.

Hi mate,
After five years or more in use, your tyres should be thoroughly inspected at least once per year by a professional. If the tyres haven't been replaced 10 years after their date of manufacture, as a precaution, Michelin recommends replacing them with new tyres.
