I'm needing to replace my KOs and I've narrowed it down to Ko2s or Trail Grapplers. I realize one is an all-terrain an the other is a mud terrain tire and the latter weighs about 10 lbs more. I like looks of the Trail Grapplers but I'm a little worried about road noise, since it is a MT tire. KO2s are a load range E tire, while Trail Grapplers are a D, so the ride might be a bit stiffer on KO2s. I would say 99% of my miles will be on pavement, I think I'm pretty much done with off-roading this truck. If BFG had just made the KO2 in a D range I would definitely be going with it, but they don't, so I have a slight dilemma.
