My GG AT3s did 48000 miles and are now at 3 and 4 mm.
Bought a set of 18" DS alloys which came with part worn Pirelli Scorpions. Used them as summer wheels for a couple of years then fitted a set of Continental Cross Contact ATR last autumn. They've done 10000 miles now and looking good. Not sure they'll last as long ad the GGs though. Landrover - turning owners into mechanics since 1948
