Re:
All tyres involve compromises. Other things being equal: lighter will be faster; however, puncture protection will add weight. Knobbly tyres will get more traction in mud and dust but be harder work on the roads: conversely, smoother tyres will roll more easily on roads but slide more where knobbly tyres excel. Then again, the design of the knobbles can make a difference. Fatter tyres will tend to have a larger contact patch and therefore grip a little better but they will also tend to be heavier. You've just got to decide in which respects you're most prepared to compromise.
If you're prepared to sacrifice some puncture protection, Continental Race Kings are another tyre worth considering. (Incidentally, the Land Cruisers are pretty heavy but comparable hybrid tyres from the likes of Continental are actually heavier!)
