I am NOT a rough driver and would want to know that how frequently are the Front and Rear Brakes and Pads needs to be changed?
Also if you can mention that how frequently are the tires required to be changed?
depending on tires equipped, 10k miles to 40k miles appears to be about the norm.
brakes is far more subjective as driving habits and methods has much greater impact.
i'd bracket brakes in the 15k miles to 40k miles as well.
