I would go Cooper ST Maxx.
Just put these on my Sierra......
I've had several sets of BFG T/K KO's in the past,(not the 2's) but the majority of the reviewers rate the Maxx better than the BFG's, so I decided to give them a "spin" this time.
I was seriously considering a set of Coopers,but reading all the reviews,most say they tend to come apart and Cooper has poor customer service. I have them on my Toyota though.
The problem I have here is there have not been many replies about tires and heavy loads. Most light truck tires will work on most trucks,but I am running 9500#'s loaded on the truck and pulling a three mule slant bumper trailer at about 6500#s with a load leveler hitch.
