Why would the tires toyo, yokohama, dunlop lemans or nitto be more superior to kumho tires?

What kinds of qualities makes those tires better than kumho, based on something I heard from someone else?|||it just depends on the application.. each of these companies has a tire that competes in a certain area.. Max performance summer, ultra high performance summer, high performance summer.. ect.. and then mostly it comes down to personal preference.. i personally run cooper zeon 2xs tires on all 4 of my cars|||It depends on which models of each of those brands. Some companies are larger and have a bigger budget for research and development for the tire technology, and because of that one tire can be better than another. Kumho doesn't invest as much into some of their tires as other companies and the prices reflect that, as does the quality. They have some really good tires and they have some really poor tires.
