Don't rule out Cooper Discoverer's. I just changed 2 of the 6 on mine (actually Cooper SRMIIs) that were 5 years old. Barely starting to show weather cracks. Real nice tires and significantly cheaper. No problems with quality. Have been putting them on for years. Last American owned, American made tires.
Whatever brand/model, make sure you get 10 ply (load range "E") and not 8 ply (load range "D") for your weight. 235's come in both.
