On my last trip to Morocco (in a Discovery, via Nador) I used my old (and now balding) Michelin XPC road tyres, as the long awaited Goodrich AT’s hadn’t arrived in time.
I did sand, rocks, dunes, roads, tracks and mountains, some of it quite horrendous for tyres; and guess what? didn’t have a single puncture, or cut, or sidewall damage.
IMHO I think you are taking more care than is needed for Moroccan terrain. If you were doing mud, I would advise differently…
You could change your wheels in Almeria harbour or outside Nador harbour (nice empty street, no traffic, no hassles) but changing tyres take longer. Try a garage (they have them over there) and ask them to keep them for you…
(PS My Goodrich AT's arrived today, hooray)!
