These tires are not directional tires, are they? I looked but couldn't see where so I just put them on but a bit worry.

First set of Run Flat Tires ever. They seem to wear out too fast (especially the front). Anybody with any experience on RFT?

go to sc430 forum and see how much we hate runflats. almost everyone changed out the runflats to normal tires already. they are very stiff, harsh, and they wear fast. not to mention the super high price tag

Yeah, they cost so much ... I have them for around 1000 miles and they seem like they wear around 1/4 of the treads! oh and the brand was Bridgestone Potenza RE050A RFT
