I recieved my new wheels. I decided to replace the Matco 6 x 5 wheel to a MAtco 5 x 5 on the mains and 4 x4 on the front nose wheel. Now I am able to run a tru Aero tire and a utility tire off a lawn mower. The tires are 6 ply and rated for 70 MPH. I will have to make new spacers for all of the wheels.
