I am feeling a vibration in my 2005 ctt at 65 - 75 mpg. If I let go of the steering wheel it is shaking and car pulls to the left. I bought it certified with 8k miles. I still have about 8 months of factory warranty before cert warranty kicks in. I want to get it fixed asap. I see it on the TSB list but cant seem to access it. Any idea what it is. I just had the wheels balanced and it did not fix it. Thanks.

I head similar issue with my CS when it had the Pirelli Scorpion Zero. The dealer rebalanced and had no luck killing that issue. We recently changed tires to the Bridgestone Dueler H/P Sport (N1 rated) and the vibration went away and it's a lot less road noise.

Tire Size: 255/55/R18 XL N0

I bought new Michelin tires and had wheels rebalanced. The rims are not bent. I still have the vibration. On my racecar I get the wheels speed force balanced. Maybe that what I need to do. Thanks for all of the reply's.

I had the wheels (and new tires) speed force balanced ... and still no luck. Steering wheel shakes at speed. Not much at 55 (where wheel balancing problem is usually noticed) but it is there at higher speeds like 75 mph. Wheels confirmed not bent. Any other thoughts?
