after i replaced my goodyear tires with a new set of nankang tires my gas milage droped from 40 mpg to 15 mpg.Anybody have any ideas?When i run the car for apx. 60 miles with the engine running only 10 min. at a time,"10 miles each way back and forth to work", the milage is decent.If i drive the same 60 miles with the engine constantly running the milage drops way down.My first thought is a gas leak?
