Don't have the ATP, but I have the AT3 which is similar in design. If the ATP is anything like the AT3 (which I believe it is) I highly recommend it.
I've been extremely impressed with my tires and I'm leaning towards buying another set after I run through these. Here's what I've learned.
Tires roll smoothly for a relatively aggressive tire
They are very quiet until about 65mph where they just begin to hum a bit (even at full hum ~80mph you really can't hear them unless the radio is off)
Mine have 20k miles on them and still have easily half the tread left
They do great in snow, dirt, gravel, and rain
Adjustment up to 80psi for towing heavy loads
Virtually no tire sway when cornering hard
Mileage went down ~1-2 MPG's (granted mine are slightly larger and heavier than stock, 34" tall 56lbs) and that is with factoring for the tire size correction
Not ideal for mud (but they have always found a way to get me out)
Takes a bit more air than stock to wear properly (I try to keep mine around ~40-45psi)
They have a stiffer sidewall so the tire is a little harsher than the stock Wrangler SRA.
Will throw gravel, but they're mostly all cleared by 25 mph
I also have photo's of mine on the website in my signature if you want to compare them.
