Bestnana, thanks for taking the time to submit a review. When new tires are installed on a vehicle the fuel efficiency will typically experience an initial drop compared with the worn tires that were removed. Over the life of the tires, all things being equal, the fuel efficiency should improve.

For any vibration, uniformity, difficult to balance, high road force, or slow leak complaints, please consult with the dealer to ensure that the proper lubricant is applied to both the rim flange and the tire bead during the mounting process.  This mounting and demounting procedure applies to all tires and brands.
