I my opinion there are none. Only reason they became popular is manufacturing costs. Bias ply are better tires.
I'll have to diagree with that. There isn't a bias ply tire made that will out perform or outlast a radial tire. Manufacturing costs have nothing to do with it, it's simply the fact that a radial is a superior tire construction method.
Now, as far as Coopers go, they have been making some of their lower end and private label tires in Mexico. Found that out the hard way. We had special ordered a set of Cooper made tires in an odd size for a customer (we only had one in stock, it was USA made), when the 3 we ordered came in, they all said "Made in Mexico" on them. The customer refused them, as he only wanted USA made tires. We ended up selling him the next step up Cooper, which were all USA made tires.
