I have an 04 SC with th erun flats. It seems that when the weather has gotten cold here in the mid-Atlantic that when I make a tight turn at slow speed in a parking lot, the front wheels rotate like they are square. I get a strong "bumping" feedback in the sterring wheel. Ths first time it happend I looked to see if my lugs nuts had come off. It seems to go away once I get going, and not noticeble at speed (although I don't make tight turns). I don't think I have hit anyrhing and it occurs is tight right and tight left turns.

Any thoughts?

 

What is your tire and wheel setup? Is the car lowered? Did it always do this or just start?

 

Have you checked your air pressure? You may have a flat.

 

I was thinking the same thing as this happened to my wife's car a couple weeks ago. Even though you you touch the tire and it 'feels' fine put a gauge on it to verify. My tire gauge didn't read a thing and holy moly I noticed she had a flat on the inside of her tire. Needless to say I replaced all four RFT this past saturday with standard and couldn't be more happier with the ride.

 

Good Suggestions to check the tire pressure. That would be consistent with the "feel" of the feedback.

I will check pressure and condition of the tires onece teh snow gets out of here.
