2005 Chevy Silverado Truck Tires are Not Cheap! Best Price on New Tires Online

It is time to buy new tires for my 2005 Chevy Silverado and I am finding that they are pretty expensive.  This is the first set of tires I will replace for the Silverado (92,000 miles) and did not realize that it will probably cost around $700-$800 for a mid-level set of four tires.  I guess I was used to the small car that I could always find a great deal on tires for $50 a tire. 
I looked online at quite a few different tire stores and nothing really jumps out a clear favorite except DiscountTire.com.  They had the best prices on tires but I really would rather buy them local at a tire store (chain-store) and have them installed right then.  Walmart did not really have too good of prices for the Cheverolet Silverado either.  I guess I should be thankful that my original set of tires has lasted this many miles.  I didn't rotate them very often but they do have some uneven wear.
