i work in tires too. it's been my experience as an installer that both tires suck. nankang's i've seen somewhat. nothing special. kumho's are the new trend. they're a korean company that can make cheaper performance tires by using cheaper materials. your getting what you pay for. if you know anyone that's lived in korea, ask them if they would buy korean tires.
