Not sure I agree with that comment Gary. Maybe in the Mickey T range, or a 33" size, but Treps and Krawlers are both radial. Both IMO are better that the claws. There are others too.
This could have been down to absoloutely anything, such as tyre pressures, weight over the relevant axle. It would be interesting to do a scientific comparison but it wouldnt be easy to do. Also I am with grimace and wouldnt run a 10" wide rim. Even with my 13.5's I run an 8" rim and drove around coffs for 3 days at 8psi with no bother.
