I was looking at the newest Kumho Ecsta-MX and the tread looks like a clone of the Bridgestone S-03.

Even reading the Kumho technical marketing for the MX shows a similar silicon technology.

Anyone know what's up?

If the ECSTA-MX are 90% of the SO-3's and 50-60% cheaper, I just may go with the Kumhos.
