I have a 2011 Honda Pilot with 193K miles (original owner). Recently installed new tires (original size). Vehicle vibrates mildly at 45mph - can feel in the seats. What are the possible causes of this?
What are the possible causes of this?
Not properly balanced, or defective tires are the top choices. If you can feel it in the steering wheel it would be a front tire, otherwise a rear one.
Check the tires one by one. Make sure there is no debris or excessive rust between the hub/rotor and the wheel. If you can, rotate them back to front/front to back. Double check air pressure. Torque all the nuts to spec. with a torque wrench.
If it still shakes, take it back to where you bought them and have the tires rebalanced; see if they do road force balancing.
Hopefully that will do it. If not, I'd ask them to replace them with better tires.
Are the tires "Hecho en China"?
