As I prepare the car for Mid-America in a month or so, I noticed that my front tires appear to be wearing uneven towards the inside of the tire. I decided to rotate the tires front to back diagonally. These tires only have about 30K miles on them mind you. They are the 13 inch Kumho Solus TA11 (Terrible in the rain). Anyways, now the steering wheel appears to shimmy more than I remember before rotating the tires, Not terrible but enough to notice. Maybe its just a coincidence and something else just happen to change at this exact time but I have not been able to pin point it yet. I know the uneven wear of the tires means something, alignment? tire pressure? not sure. I have checked all of the suspension nuts/bolts for tightness, bushings look fine although I'm not sure when they were last changed. Looking for suggestions or things to check. THX
