I'm not too sure that I agree with the negativity towards the chunky off road tyre options in this thread.
I fitted BFG's in the autumn after getting stuck in a field with my All Season tyres after the ground softened at the end of the summer.
I have adjusted my driving style for the winter months (on BFG's) as they are bit crap on wet tarmac. To be fair I always knew this would be the case, but they still provide good stopping capability, albeit with a tendency lose lateral grip on wet tarmac.
They do however prevent me getting stuck in wet grass and prevent turning a pitch into a quagmire. Come early summer, I shall be refitting my 19" Cantera wheels with Goodyear All Season tyres and enjoying a quieter drive, but until then the BFG's are doing what I need.
This week, I towed my big old caravan over up an incline on grass, and whilst I noted limited traction, there is no question that the BFG tyres were the difference between "needing to take care" versus "simply getting stuck"!
