Huge difference, though, in how bias ply tires age versus radials, though ....
As for modern radials, I'm on my 4th set of Kumho (Korean brand) and am quite happy with all of them. 1 set was a Car and the other three have been all-season mud/snow for the truck and van. Just went off roading in West VA with the van on a worn set of Kumhos and they did great.
