Is this a run-flat tire?
If so, that tire is probably the replacement for the previous generation of the Kumho Ecsta SPT that was used by many (including me) a few years ago.
I got about the same mileage I did (~13k) out of that tire as I was getting from Dunlop E3's, so I moved to a Pirelli (same 13k per tire), then onto the (no longer available) Michelin Alpin ZP. My mileage jumped up to ~19k on a rear tire.
I just took off a Yokohama Avid Envigor - ~20k down to the wear bars.
Now, Murgie is a guru on these things... :mrgreen:
