I have been very happy with the ride and traction of the Kumho. Even at 18,000 miles the wet traction was still good. Couple weeks ago on I95 in a down pour while leaned in a long sweeping corner the worn down Kumho held its ground. BUT I am noticing the edges are getting warn down. The center is just about at the wear bars and for me... when I start to think about my tires that means it's time to replace the tire.
Although the Kumho has served me well and performed as I wanted, I am thinking about switching to another tire. Mainly because I have nothing to base a comparison on without trying different manufacturers.
I will stick with a run flat and keep with a high traction rating. I will now look more at the edge tread as that seem to be my faster wear point.
Maybe a Yokohama AVID ENVIGOR. any thoughts......
