Mine has an up-and over door and switching to side hung doors should be enough.
The up and over has a small gap to the door lintel, then the thickness of the door, then the lock and handle and opening bars that sit below it.
I’ve forgotten the measurement now - but going to side hung doors gets rid of all that, and that’s enough for me to get in.
Mind you … I am thinking of taller tyres 😳
I’ve only just joined the dots on that thinking.
