I just bought some new Toyo tires a month ago for my SC300. After that, I noticed a vibration when driving at 45 MPH or above. I have moved the tires around to try to isolate which is the problem, but have not been able to find it. The tires have been rebalanced, but that did not help.
The tire shop says that it is not the tires, that it is the universal on the driveshaft.
I am not convinced. I am very convinced that the vibration started when I got the new tires.
Here's my question - can the driveshaft (or something else) cause this vibration all of a sudden and how can I test for it? Any other ideas?
I spend 2.5 to 3 hours in my car everyday at highway speed, so I am pretty in tune with its operation.
I think I may go back to the tire shop and tell him I'll pay him to mount a new set. If the vibration is still there, I eat the labor. If the vibration is gone, he takes care of it.
Thoughts??
