It reads too much like an advertorial for my liking, and it seems unlikely that Bridgestone would go from being the manufacturer of the worst runflat to the best runflat in one step.
Like you though, I will be interested to hear if anyone has tried them.
mmmm agreed problem for me when the 3rd generation came out they were according to The Press just 5% off the feel of a normal tyre and yet they are still complete howling crashy pants
