I am having the same problem with my car which I just discovered last night after I picked up my car from CDN Tire for the tire change. I sent it back to them for a checkup and they just called me that it was not caused by the tire change. (Note that both my ABS and Traction Control lights are on and I hear that clunking noise from the brake when starting my car). I will see what they find after they notified me that they'd charge me inspection fee.
