Ever since the third service a few months back, during which they 'balanced' the wheels, I have been facing a slight steering wheel shudder when the speed reach over 80kmph. Being driven mostly in the city during these months, I never really got a chance to verify this. I experienced this just a couple of times. I suspected some goof-up by TASS during wheel balancing, so ordered a set of hub-centric rings from hubcentric-rings.com. They arrived two days back and today I took the car to a local shop. Sure enough, the ring was missing from the left front wheel though they were present in all the other three wheels. :irked With all the wheels balanced again and the new set of hub centric rings in place I took it for a test drive. Now it feels butter smooth at speeds of 110kmph measured on my mobile phone GPS - with speedo showing around 120. Didn't find roads to take it any faster. Now I got back the confidence for taking it on highways again.
