Well everyone's got an opinion on this forum
If you want to read in depth on tyres (or any other topic) just use the search feature, whatever you want to know has probably been covered 10 times already, and some of the old kodgers get really upset when the same stuff keeps coming up again because no one has bothered to search
If you can't find the answer post a question in the relevant technical forum.
But my opinion on tyres is get BFG Mud terrain, or Kumho MT's. A recent Land Rover Magazine test rated them joint winners as best all round Mud Tyres. Kumho's r slighty cheaper.
You can get better tyres, but they will cost **** loads more, and perform worse on the road.I wouldn't go cheaper than BFG's or Kumho's, cause it sucks getting stuck when everyone else is getting through. You could look on ebay, but make sure there is still enough tread left.
O and when getting a steering guard look for one that has integrated recovery points, makes life easier (and then you just need to worry anout the back )
