Prior to this trip I would have unconditionally pledged my allegiance to those tyres. I've done 2 sets of them in Australia, never had a puncture, never experienced blocks of tread coming off, and never been properly bogged in sand. I used to love going to Fraser and watching people hit the exits at Mach 5 only to get bogged on the first corner; while my pizza cutters and I would crawl past in low range at 16PSI like it were all a walk in the park. If they're good enough for the ADF, they're good enough for me.
I had multiple punctures during the trip. All sidewall I should add, but I picked up punctures where others did not. Luckily in Morocco OH&S is not a major issue and I had a vulcanised repair done on one that should have been scrapped for the princely sum of $2AUD. I lost lots of blocks of tread too and went through the set in 40 odd thousand kilometres.
More importantly, I got royally bogged in sand dunes approximately one million times. On level straight ground, the 7.5R16s can be aired down to almost nothing and you can get through anything. Add 800 kilos (the wet weight of all the fruit on and in my truck including drive and passenger), and rolling soft sand dunes where you have to maintain speed whilst executing extremely tight turns on crests to avoid rolling down the 60 degree fall sides and you have nothing but tears. I rolled one tyre off the rim at one point as the only way I could get up the big dunes was to run 8-12PSI. With that amount of weight, and the Puma's inadequate engine capacity, to properly impersonate a Tusken Raider you simply need wider tires. I recognise aired down longitudinal tread length comes from tyre hight but it doesn't hurt to have some latitudinal breadth to start with.
Another fun fact learned as a result of the bog-fest, MaxTrax bend like bananas in 45 degree plus ambient temperatures, and lord knows what temperature hot sand. It makes them decidedly useless if you're on a steep incline. I managed to bend them back by finding some flat scorching ground and flipping them and parking on them for a few hours.
Short story: I am now going to buy a set of 255/85/R16 BFG KM2s when I manage to restock the bank account.
