Question 90574: The new tires in George’s vehicle are 15.5 inches in diameter. They are guaranteed for 75,000 miles, meaning that the thread will wear less than 0.50 inches in 75,000 miles. When he got his new tires, George had determined that he was getting an average of 34.55 miles per gallon of fuel. He got suspicious of the tires when, after 25,000 of driving, his mileage improved to 35.00 miles per gallon; and he was sure of his problem when after another 25,000 miles, his mileage was 35.47 miles per gallon.
Please, use the information given to help George make a case to return his defective tires.

I BELIEVE YOU ARE MISSING A KEY FACTOR IN THIS PROBLEM AS THE TIRE WEARS THE MILEAGE TRAVELED GOES DOWN NOT UP. AS THE TIRE WEARS THE DISTANCE TRAVELED PER ROTATION IS LESS ERGO THE MILEAGE IS LESS NOT MORE.
