What type of tires?
"Directional tires" may be "high performance tires" that tend to grip more. So, I had to get used to the tires gripping every bump and seam in the highway, and the vibration & humming from the grooving they put in the highways around here in order to increse traction during heavy rains.
But agree...first double check the the tires are mounted so they rotate in the directions of the arrrows on the side walls.(when you are driving forward)
