Karolyn just purchased a new set of Goodyear Assurance 225/60R17 tires for her 2014 Subaru
Outback, which has 84,358 miles. The tires have a diameter of 27.6 inches and are warranted to last
for 65,000 miles. How many times can Karolyn expect her new tires to spin on their axes before
they need to be replaced?
