I buy my tires based on people's opinions here and others that I know personally and what I've driven on in the past and since I work part time at a body shop i get to drive alot of vehicles with a lot of different tires on them.
The final nod to my getting my Nittos was based on several tests I reviewed and Bamachem thought they were a great DD tire and decent off-road and their price was much cheaper than the BFGs.
