I'm sure that you made the right decision(Grabber HTS)as they are ConsumerReports top rated truck tire. What truck/suv did you put them on?
Although a friend of ours has KR-21's on a Honda Pilot and likes them and I have seen them(KR-21) on Ford Expeditions. Our friend thought she needed an "SUV" tire just because it's an SUV. I said to her "you only drive the Pilot like a car"! We just don't know yet how long the KR-21's will last, otherwise they're doing fine.
