Question 975176: two new cars are each driven at an average speed of 60 mph for an extended highway test drive of 2000 miles.

If the cars use tires of equal durability and profile, differing only by the diameter, which car will probably need new tires first.

-------------------------
If there are no other differences, such as tread thickness, the smaller tires will wear out first.
