3 inch tires on 4 inch rims?

[HumanPerson]

Oh, so you replaced a 26*4 tire on your fat bike with a 26*3 tire on a 4 inches rim and it fits all right?

I've done the same with the same tires.
Works great as far as only street riding is concerned....in my opinion.

Welcome to our humble home by the way
