Re: Shake/Vibration from 65 mph and higher
Did you have this vibration prior to the new tires? If so, it could be anything from a funky rotor to a motor mount.
You didn't mention a fresh 4 wheel alignment with the new sneakers, was that done? Not trying to insult you but,
are you sure the tires are the correct size?
Tire balancing is an art, Sears, NTW, Joe's Tire Barn, etc, these guys do lousy jobs. Have a good friend recently
b!tch about vibration after new tires installed/4 wheel alignment in a '10 Slade. He drives the car likes its stolen,
just like me. Recommended he take the slade to a performance shop for balancing, worked like a charm. YMMV.
An 07 is 6 years old now. If the tires are quality, properly balanced, 4 wheel alignment has been done... you're
looking at a funky rotor, motor mount(s), a bad pulley, who knows. I'd start with 4 wheel alignment (yes/no) and
balancing at a good shop, go from there.
