Check out FMCA's tire program if you decide to not go with the Sumitomos. They have the Michelins for $412.78 + tax. They do not offer Continentals in your size. You get the tires through a local tire dealer who you pay for mounting and balancing. The tires themselves are billed directly from Michelin.
Used this program to put tires on my truck and got them through FMCA at $10 less than dealer cost each. My neighbor is the manager of the tire shop that mounted them for me and he was surprised that FMCA got them cheaper than they did.
