Cold tires
Good day all, during those cold morning starts, it sounds and feels like the tires are rubbing on the inside of the wheel well while attempting to turn sharpe. The only other thought or example I can provide is that it feels as if the tires have a flat spot. Any thoughts?
Thanks
Thanks

The thumping works itself out after it is warm. Does this deserve a trip to the stealership or is it just something I have to live with? I will try the figure 8's but exactly what does that accomplish?

I bet what you are listening to is your rear differential clutch packs binding. This is the normal operation of that type of differential; both rear wheels are tied together by clutch packs immersed in a fluid; when cold, the clutches have a tendency to bind, locking th wheels together; tehis results in a popping sound when you turn the car because one tire is dragging on the ground or from the clutches binding and unbinding since on turns the tires should be turning at slightly different speeds. The figure 8s works the fluid in between the clutches and makes the problem go away for a while. A fluid change will make it go away for longer, but that noise is something all vehicles equipped with clutch type differentials have at some point or another. Nothing to worry about.

This issue has been discussed quite a bit and it is most likely the cold tires reacting to the cold temps - especially the GY run-flats. The sidewalls are the big culprit. It happens when the temps drop below about 35 or so and as soon as the tires get warm (or temps or both) the problem goes away.

Lots of threads lately with all the cold weather across the country. If the sound is coming from the front this is the problem, if from the rear you might have the typical diff. problem.

cold GY run flats. I have the exact same problem. It feels like the wheel is hitting the inner fender and bumping vibration in wheel.
I had the rear clunk and then fluid change. Its a different feeling. I felt that more in the seat rather than the steering wheel.
