I just bought a 2015 Mustang
I just bought a 2015 Mustang with the V6 motor. It came equipped with the Goodyear Eagle tires. I cannot drive the car over 45 MPH before the tires start to make the driving almost impossible due to noise and the unending small but impossible to accept vibration that gives anyone in the car a headache.
I had this same problem with a 2001 Lincoln LS that came equipped with Continental tires. After 3 trips to the dealer without a resolution, I had to buy new tires (not Continental) at just over 20,000 miles to correct the same conditions I am now experiencing with the new Mustang
