Floatation tires on 8 bolt rims

Set of 4 Alliance 550 / 45 - 22.5 floatation tires on 8 bolt 16” rims. Came off a Weberlane 20 ton dump wagon. One has a blown sidewall. Rims excellent condition. We switched to road tires after the blow out happened so now we have these floaters leftover. I have a spare tire to replace the one that’s blown but the tread profile will not match. Dimensions are the same. Spare tire is an Alliance A-380 floatation radial 550 / - 45R 22.5. This tire is included in the price and will sell as a complete set. Open to reasonable offers.
