Very interesting comments through out.
I am currently in Morocco/Marrakech. and have to buy new tires (heading to Mauritania in September, later Mali Niger mybe Algeria and back, West Afrika next year). With limited availability of sizes and specifications (here in Morocco)...
BFG MUD are not available at all
neither any MUDs of other makes.
BFG All Terrains the 235/85 R16 are avail (NOT so the wider tires).
Alternatively Pirelli Scorpion A/T 265/75/R16 are avail. These are the ones I have had on so-far and quite liked. Lowering them down to 0.7 kilos (bars) alowed dune and beach driving (Merzouga, Plage Blanche) at ease. Keep in mind the vehicle is a Defender 6 wheel, very heavy, normal 300TDI engine.
The question is how low can I deflate the BFGoodrich 235/85/ R16 A/Ts in order to achive the traction on sand, that I need with a low powered engine??
I am sure the Pirelli A/Ts as compared to the MUDs have the same wear problem you described in detail for the BFGs.
Thanks very much
