Folks,
Finding 20x7 smoothies for 8" rims isn't easy. I have the original landing gear on my 92 Kitfox IV Speedster, and Cheng Shin 20x7s on 8" ATV rims.

I am very interested in the Nanco's 21x12x8s but I don't want to purchase them until I'm confident they will have enough clearance given that I'm going from 7" wide tires to 12" wide tires. I could be happy with two more 20x7s but finding smoothies seems impossible.

Anyone else swap out a similar size tire with these? Any suggestions would be appreciated very much.
