They are an AT/Mud hybrid. Quieter than a mud tire and a little more aggressive than a standard AT. They have been very good so far.
I run Blizzaks in the winter. The Maxx may be fine for the winter depending on where you live and how much ice you have to deal with. I haven't really given them a fair trial in the snow. The Blizzaks are simply amazing in the winter.

I've got Cooper Discoverer S/T Maxx Tires 315x20x17. They are fairly quiet and not bad in the snow and ice. Most of the side roads have what we call hard pack on them that stays from October to April. Hard pack is compacted snow and ice.
I haven't had the opportunity to go off-roading yet but summer will be here in May can't wait...
So the Cooper website doesn't list the Maxx at anything bigger than my 275s. Treaddepot.com however lists a much larger range of sizes. I'd heard they were planning to expand the size range, but am glad to see how much they have done so.
How are the all terrains as a daily driver? In the snow as well? Hows the gas mileage?
Alot of questions..i know lol Sorry
Sorry, to clarify I have the STT which are considered MTs, I think the STs are the AT tires of which I have no knowledge. This is my wife's Jeep and she has no complaints so I assume they work well enough as a DD tire or I would hear about it They are better than the BFG KM1 MT they replaced in the snow/ice and are just as good or better in the mud while being surprisingly quiet on the road. Gas mileage is down about 1 MPG but this I would attribute to the size increase, going from a 32" to a 35".

I had the Discoverer STT's and they performed well at low pressure. Good traction on wet roads and relatively quiet on the highway. Only slight complaint is that they have thinner sidewalls compared to others.
