The H78-15ST tire size is the same as the 225/75-15 tire size like the part # TTWSF22515D that you referenced.

I would recommend the radial version of this tire # TTWTRTM2257515D over the one you referenced as it is a bias ply. Radial tires run cooler and have more flexible sidewalls for better ground contact. The Taskmaster tires also have a higher speed rating at 81 mph which is nice since most tires are only rated for 65 mph.
