Late night emergency and only one place to buy tires. CS4 recommended. What a disaster. This was early October, no change in gas as yet. MY mileage dropped from 52mpg down to 44 right after the tire change!! I can not get over 42 most days now with winter gas. They don't handle well on slippery roads either. driving on snow covered roads, you can't exceed 40mph on the best stretches.
