Have just checked their website and it seems they've improved things though the 235/85R16 is still only rated for 87mph where the rest are 99mph.
Been looking at the similar tread pattern Fedma Trekkers myself (cos of the different sizes they do, though I can't help thinking that they're both a bit too aggressive for green laning. The sheer difference in ratio between tread block and gaps must mean they do more damage to softish surfaces due to the icreased pressure. For pay and play they're the bees knees, but not sure about laning, even on fedimas own site they ae listed as a competition tyre not an offroad tyre. aving said that I'm truggling to find anything larger than a 31" thats not also 12.5" wide ad I don't want to go that as I'll have to go for arces etc so 10.5" it will ave to be.
