My Chevy volt has 199k miles and it's original brake pads and rotors are definitely almost new looking, but I'd say to be conservative they are 60%.
My cheap Chinese Walmart tires have lasted me 50k miles and are due to be replaced soon, but I spend zero attention to driving smoothly or in an eco mindset.
