Beyond 20,000 RPM!
Kumho have launched their new Extreme Performance Ecsta V730.
Looking at the thread pattern, which looks similar to the older V720, but grooves are more shallow.
Outer shoulder pattern is wider, shallower, looks towards improving overall dry and corner grip, however looks like wet performance will be lower due to shallower thread pattern.
At the moment 6 sizes available, more to come later....
