The only weak point of the Duratrac is the sidewall IMO. They are very thin but despite that there have not been too many reports of failure. I have a set studded for winter use.
I have been happy with my Generals (red labels) but I don't run them in the winter. They are sticky on the rocks and quiet on the HWY for what they are. Sidewalls are very stout. Weak points would be tread wear & winter.
Previously I had the Nitto TG's which were good year round. I'd buy those again for a year round application. Plus they are available in a 295 which gives you just a little more without the drawbacks to 315's.
I had BFG AT's on my 60 and hated them.
