Be warned with 20mm internal rims, they max out at 90-100PSI maximum tire pressure (max pressure goes down as internal width goes up). To use wider format rims, you may need a wider tire to get the necessary/desired pressure number for your rig's load.
Granted, 6 to 7 bars.
I seen even lower pressure restrictions on tubeless compatible (hookless) rims, which narrowed down my choice to hooked rims.
According to DT Swiss's Chart, 28mm tube on 20c rim is 7.8 bars (113 psi) max when tubed, 6.3 (91) when tubeless.
If I choose a hookless rim, that goes down to 5 bars (73 psi) so no hookless rims for me!
