Welcome to the forum. Not sure where you are from. We have a cooper tire dealer here in Orangeville. Fred's Tire. If you give them a call, they might be able to point you in the right direction sense they import tires in from all over North America. Just a thought.
I've used Kumho's on my Suburbans with no problems. However, I went to replace tires last week, and the dealer told me they replaced Kumho's with Cooper, so now I have 4 new Coopers. Still under $600 for 4 tires.
