better reference ETRO numbers ..
406 is the common 20" 2nd number is the width 47 is like a 1.75"
that would be imprinted on the side of the tire itself.
I use Schwalbe Marathon Plus 406-47 tires
(Bike Friday adopted the BMX sized wheel for their travel bikes)
FWIW, your rim should be narrower than your tire width ..
