Wanted to get a bit of impute from you guys. What do you think, should I keep the KM's or swap out to the Coopers. Can the oweners of both chim in, pros and cons would be much appreciated.
Just run the KM2s. They are very "AT" for a MT tire. The road manners are great, and since you already own them, they are "free"!
I can only tell you some basic info on the tire choices you have. I am sure other will chime in soon with much more factual information
You are talking about going for a MT to a AT. You say 90% is on asphalt then I would move to the AT. It would also depend on when you are off road how nasty of terrain you are in. If that 10% off road is really nasty mud or sand or whatever then you may want to consider keeping the KM2s just for that 10%. With religious rotation and tire pressures people are getting 40k out of their KM2s.
I had thought about the Discoverer STs as well buy kept hearing they are very soft. I am waiitng for the Discoverer ST MAXXs to come out in the next couple months in the 255/85-16 size.
I dont know if you have already or not but you may want to go back and read this whole thread. It has a tone of info in it.
FWIW...
I have owned coopers and currently own KM2s, and I grew up in South Florida. KM2s are a fantastic off-road and rock tire, and very quite on the road. I run them on trucks in both New England and Central America. But, IMO, they are a bit weak in fine organic mud, which there is an abundance of down there. Generally I am not a fan of AT tires, (I'm the same with all season tires too) go either street or off road (or snow tires); something in between falls short at both ends of the performance scale. Albeit Duratracs have opened up the performance window of ATs quite a bit, but also are poor in mud.
When I lived in Jupiter, guys who actually wheeled (as opposed to the e guys that ran 37" tires and 10" lift but never left pavement) ran a "mudder" type tractor tire, that paddled through the muck. And there was always a debate of wide for float or skinny to cut through and find grip. Many guys would have two sets of tires: mud and street. If I lived back in south Fl that approach I would take. Nice quite SUV road tire 90% of the time bad-***** mudder for 10% of the time. If you are only going of road in dry sand, you could run just about any tire and do fine. I recently picked up a slightly used set of SS TSLs that were grooved, and they are by far the best mud performing off road tire I have ever owned, but VERY loud on tarmac.

Clearly you are not FloridianI'm not into mud bogging shooting beer and pulling cable every every 5 minutes....
Another personal data point for you: I find the KM2s sketchy on tarmac in heavy rain. They hydroplane A LOT. I would be very apprehensive driving with them on say 95 or the Sawgrass during a summer deluge when the traffic suddenly slows to 20MPH.So since we get gobs of rain during the summer months driving into a cement mill can be nasty if you aren't careful. This was one of the reasons I went with the KM2 although my T/A's were phenomenal
I'm so sorry....Mine came with a jeep, loves to wheel, and is shopping for a BJ45 right now...She's not much of a 4x4 type of gal.
Where in that .pdf do you see an AT in 255/85R16? I only see the AT in 195/75R14 on page 83. (Mail truck tire)
I'd buck up for some 255 AT's if they made them, as I really liked those tires!

<EDIT> I found them!! They're on the chart on page 49 but not in the back, where the AT only shows up in the tiny size... I found some old reference to them (circa 2004/05) but nothing newer than that, and I can't find them on any tire websites... I think you're going to travel back in time to get them, or if you do find some, they'll be 10 years old or so I bet... Dang it.
Wow, those 4-rib Wrangler AT treads look the same as what I put on a truck in 1990-ish. Not bad looking either, but no 255/85, right?
