I went through the same delemma. Since my rear tires were like new I started calling arround to see what I could get. Most places couldnt get 7.50-17 tires, and one told me that he has installed 235/80R17 tires on old Chevys and they work out fine. I finally found a place that could get me Samson Traker Plus Highway tires in 7.50-17 for $193 each (Canadian dollars) and bought them. If you are in the US Summit racing sells the Coker tires, but shipping to Canada was to expensive for me.
