After couple attemps to get car tire on my C10 last week it all came together. I tried first with my stock 16" wheel. I had read where it had been done. The smallest tire I could locate was a 175R16 Maxxis. It will not work! rubs swing arm. Then I found an article from back in 2008. Car tire using a wheel from a 1987 ZL1000 Eliminator. It takes machining of some parts but it all came together. 15" wheel and a 165/80-R-15 tire. I am sure it not for everyone I have couple small rides and 250 miles on it. I like it!! I am sure I will receive lots a negitive feedback on doing this. But I also have a Goldwing and have riden over 50,000 miles on car tires. If I can figure out how to shrink pics down enough I will post a couple here.
