Yes. These tires can be replaced in sets of 2 across from each other on your Magnum model. They use the same 8" rim that is on your vehicle. The tread pattern is deeper allowing the tire better traction in mud and in the water. It is recommended to replace the tires in sets of 2 and placed across from each other so the vehicle does not pull left or right due to the increased traction of the new style tire.
The Goodyear Runamucks have been discontinued and are no longer available in the marketplace.
