my current bridgestons tiranza runflat have about 43,000 on them thinking it is time to replace them. My options are to stick with the bridgestone or move the the conti. I have been told by dealers that the conti run longer anyone had any experience with them? Also recently had low pressire indicator go off on current tires brought them in and was told a nail was causing the problem, they patched the runflat, which I didn't think you could do. (I have the road hazzard insurance) a month later my car went in to another dealer for standard service and I was told there is a bubble in the same tire that was patched I think these events may be related, but prob impossible to prove, any suggestions?
