Thanks for the kudos folks.
Pulled the rear tire/rim off this afternoon........I have finally realized the meaning of "shade tree mechanic' as I did the job while camping in our toy hauler, behind a friends house. Local tire store agreed to switch out the tires for me, if I bring the rims in. First the rear.......pretty straightforward, and then the front. Also ordered new brake pads, and new air filter. Doing all of this now means I will have a head start on the build when I get back to texas.
