2004 Dodge Intrepid Owner Manual - Page 143

STARTING AND OPERATING 143 Rotate your tires at intervals shown on the maintenance schedules. More frequent rotation is permissible if desired. The reasons for any rapid or unusual wear should be corrected before rotating. • uneven tire wear, such as feathering and one-sided wear; • vehicle pull to right or left. Tires may also cause vehicle to pull to the left or right. Alignment will not correct this condition. See your dealer for proper diagnosis. Improper alignment will not cause vehicle vibration. Vehicle vibration may be a result of tire and wheel out-of-balance. Proper balancing will reduce vibration and avoid tire cupping and spotty wear. 5 The suggested rotation method is the "forward-cross" shown in the diagram. Alignment And Balance The suspension components of your vehicle should be inspected and aligned when needed to obtain full tire tread mileage. Poor suspension alignment may result in: • fast tire wear; FUEL REQUIREMENTS Your engine is designed to meet all emissions regulations and provide excellent fuel economy and performance when using high quality regular unleaded gasoline having an octane rating of 87. The use of premium gasoline is not recommended. The use of premium gasoline will provide no benefit over high quality regular and mid-grade gasolines, and in some circumstances may result in poorer performance.
