Angelina’s husband wants to replace their Civic’s 13” tires with 14” because he thinks it will improve their gas mileage, and save money. Angelina is a former math teacher, and thinks this makes no sense. Tom and Ray say Angelina’s husband is right--bigger tires will improve the mileage, but you have to account for the cost of the bigger tires and wheels, so it could take many gallons of gas to break even.
