There was a problem with a batch of the camo extreme tracks last year and they quit selling them until the problem was solved. They did a new mold and a new run (or what ever the terminology is) and started selling them again. So far, no issues for me or my buddy that just got ours this summer.
I was very leary of running a 3 inch track, considering my 2.5s would start losing lugs after the first ride, but I have to say two rides now on my 162x16x3 I am impressed. We have had amazing snow in SW Colorado lately and the 3 inch was awesome, and has been holding up well too.
