Tested the pitbulls yesterday.
MUCH better than my Maxxis muds, could actually feel it making grip/biting.
Was one section where I got stuck and had to winch.
Funky kipper was first through and he drove it, I got stuck.
Unsure of the reason but yesterday confirmed my upgrade was worthwhile.
Very pleased seeing as they work, they don't rub too bad now I've adjusted the arches a bit, they look dope and are a fun tyre to have on the car.
Kipper is on simex pattern 33s and they were still better though, and that was dealing with more peaty mud than I've ever seem before.
Hope that helps your quest.
In fact now I think about it, I was ok all day in peat but got stuck when we hit that clay bit and my tyres filled whereas his didn't fill as bad.
So there you go, case solved
