I have 265/70 R17 General Grabber AT2 on my Patrol. They are available in a number of 17ins sizes, IIRC.
I did consider the Kumho KL71s when I bought the AT2s - but they weren't readily available at the time. It also bothered me that they were directional, so there's only a 50-50 chance that the spare will be any use other than as a "get-you-home". Also, I reckon the AT2 will be better than the KL71 on snow and on dry/wet tarmac and on most unsealed lanes. Obviously, the KL71 will be better on deep, gloopy mud - but from memory, the only time I've seen any of that recently was on Gorbeck Road for a half mile or so - and the AT2s did OK even there.
