I did a lot of reading about using a car tire on a C10. I did some trial and error to get it correct. I have been running a car tire on back of my 2006 Connie. Worked out well. I just bought a Goldwing and put the bike tire back on the Connie. I have tire, wheel, brackets and spacers to install car tire on a C10. Tire has approx 1,000 miles. If you would be interested in purchasing this set up let me know. If you run lot of interstates or pull a trailer. This set up is great!!
