I wasn't in a hurry for new tires but Sears online has Bridgestone R187 8/R19.5 tires on sale for $242.84 each (plus blah, blah... Reg price $263)

They will cost me $512 for the pair, mounted, balanced, new valve stems and taxes out the door! I will bring the wheels to them loose. (The shipping is FREE to a Sears store, shipping costs are what killed the other quotes)

This will give me new tires on the front and a much better left over for my spare. These are the best prices I have seen for these name brand tires (same as the other ones on my coach.) Not sure how long these prices will last.
