I have never heard of Achilles tires, but they look good. And so cheap! Wow...
Have you done any high speed or track testing?
I like the Toyos due to their extensive racing development. They also wear like iron despite their very sticky compound.
I will post some pics on the 15x10 wheel. They look very similar to the Achilles in terms of fit.
With all of these options, it is a great time to be running 15" wheels.
