Dan, We had some misfortune at the farm next door over the weekend. One of the Holstein cows suffered a fatal hardware disease. Maybe I could arrange a leather spare tire cover--uncured, hair-on, black and white leather spare tire cover. Just a few minutes with a chain saw and a sharp windshield scraper, by the time I get to Carlisle it might even be dry and form-fit to the spare. Don't delay, this offer gets less appealing as each hour of sunshine passes. By the way, that wheel is 4" x 15 not the 4.5 that I mentioned earlier so the whole package is just 4" x 22". It's holding air, too. Maybe four of those would give you the look of the modern cars with the thin tires and close to the ground? You just have to keep the car under 50 MPH and the tires inflated to 60#. And you need to change the tires every 100 miles or so. But it would look so cool to cruise around the block and and back into the garage.
