Have you gotten the Dunlops mounted yet? I'm about to pull the trigger on the same set, but wanted an opinion on them before I order. I am primarily concerned with handling while turning as the reviews say these are great for braking/accelerating but are prone to side slippage. I drive a lot of twisty highways in the winter.
I do have to say I'm pretty impressed with the stock Bridgestone Dueler H/L Alenza in snow (under 2"), but I'm sure a lot of that has to do with the fact that they are brand new tires with deep tread. I am guessing their capability will diminish greatly as they wear a bit.
I'm getting the Dunlops mounted tomorrow. I'll let you know.
Here in MN we don't get much snow - maybe only 50-60 inches a year - and the plows get out early so there is rarely a time we have even have an inch on the roads. The bigger issue is packed snow, ice, and those days it's too cold for salt be the effective and everything gets "greasy".
I spend 2-3 days a week on straight 2-lane highways outside town, which are usually windswept and (especially in the mornings) there are occasional icy patches.
So, where I live and how I drive, true "snow tires" with compounds that get more flexible and grippy when cold are much better than deep lug treads, or even all-season tires which have the 3-PMSF symbol.
The issue I have experienced with the Dueler H/L is when braking and turning on slippery surfaces there is much more understeer than experienced with dedicated snow tires (on admittedly lighter vehicles). I also don't (yet) have confidence that when the Duelers lose grip it'll be a gradual loss with a chance for recovery, or if it's "straight in the ditch" (or worse).
The additional benefit of dedicated snow tires is that I have them on 18" rims, and they are 'standard load' which helps to maintain some comfort when the cold brings out the frost heaves. Then in the summer, when I tow more, I'll have the benefit of replacing the 20" Dueler's with 10-ply tires for better towing (the truck isn't my summer daily driver).
And yes, I have often been that I overthink things and suffer from "analysis paralysis".
