I've found the best tire value in buying a major manufacturer's second or third tier brands, and Bob's post would be an affirmation of that. Those brands are typically made in the same plants as the big name tires, but sell for significantly less as you move down through the brand hierarchy.
The Dunlop tires that Bob is happy with are Goodyear's second-tier brand. The Kelly-Springfield tires that I have on my Kenworth are Goodyear's third-tier brand, and I've been well pleased with them since buying them five years ago.
If you're a Michelin guy, their second and third-tier brands are BFGoodrich and Uniroyal, respectively, and are priced accordingly relative to the flagship brand.
If you like Bridgestone tires (which will be within a very few dollars of an equivalent Michelin at the top of the price sheet), consider the Firestone and Dayton brands.
And if you're a Continental fan, look at Generals, too.
