Totally agree about the BFG AT's,had them on my Disco 1 and have loads of customers with Defenders on them,farmers,tree surgeons fencing contractors etc getting huge mileages out of them and good off road grip too.Trouble is they don't make them for 18" rims,which is why I ended up with the General Grabber AT's.I have plenty of D2 and D3 customers using them,good mileage,but not quite as good off road as the BFG's.The GG's are also very quiet on the motorway and don't follow tramlines.
