I had more punctures than you and decided to put stouter tyres on.
I found taking the rear wheel off easier on a bike with a rohloff hub than a derailleur equipped bike.
Disconnect the rear brake at the noodle to open the arms, deflate the tyre if still necessary to clear the brake. Put the hub in 1st or 14th gear and note which it is before disconnecting either the external gear mech, or the cables to the internal gear mech. Loosen the wheel retaining nuts or quick release and take the wheel straight out. Lift the chain off the rear sprocket and park it on a cloth on the chainstay.
The wheel is now available for whatever work you plan to do on it.
To refit, reverse the removal process making sure the gear changer is still in the original gear.
