We have the same problem finding Goodyear Excellence run flat tires. 3 of our tires developed bubbles on the side wall after 8000 miles. Goodyear told us they have stop production until March 2011. We bought our car in Sept 2010 and have being trying to find the Goodyear Excellence 245/40R19 tires since January. I have never experienced having this many bubbles on tires and finding out the manufacturer have stop production on this model.
Now I have too look for another brand just for the front or change all 4 tires.
