Gave my new ATZ P3's a run up the snow on the weekend. and I'll be honest, I had almost talked myself out of them being any good before I even hit the dirt.
This is my first set of AT's after dozen or so sets of muddys over the years... BFG, Kumho, Goodyear, Simex, etc..
On the road, I've only got few hundred klms on them, but they have been good so far.
Wet Roads - they are great, and give good feedback...
Hardpacked dirt - Seemed good.. no issues there
On loose dirt roads they were controllable when you wanted to play in a corner, and stable enough when you didn't.
Slop - Down at Comet Flat in the mud, they didn't spin up when taking off in the slop unless you wanted them to.
On the powered snow they were good, but sometimes I thought I'd have done that easier with a muddy. maybe.. maybe not.
On the ice - it didn't really matter
The only time I winched was a section of Barkly where there was a tree down across track, and partly buried by snow, and I lost momentum and that was that.
There was another dude there with a set on a 100 series, also only week old and he seemed to have more issues than I did...
Jury is still out, as that was first time out, but they seem a pretty good thing so far.
