LTBs are a great off road tire, they
do excellent in soft dirt, sand and mud,
I think they are a little less than great

presurve your axles on the slickrock
in moab, driving on slickrock is about
like driving on the street in 4 low
I never had any size other than the
33x13.5-15 so I don't know how the
31s will be
