Everybody's got an opinion, and some won't be changed by the facts. Here's mine.
The new snow rated all-weather all terrain tires may be the best compromise between traction and convenience, but the tire with the most traction in snow and ice is the tire designed to be so by the tire company who invented snow tires. In an emergency stop or avoidance maneuver, you will stop faster and avoid better with the studded Hakkapallita SUV 9 on your SUV instead of those new all terrain tires - regardless of drive train.
Is it worth the the traction you give up on dry warmer pavement? Well, why are you buying a winter tire in the first place?
BTW, studies have shown the fastest way to stop in loose gravel or deep wet snow or deep sand is to lock up all four wheels and dig some trenches.
The new breed of all weather tires is not the best blend of convenience and traction. They have the broadest traction spectrum.
It’s like skiing an all-mountain ski. Remember not long ago when all the luddites were claiming that these skis were dangerous just getting back to the lift?
I have gone sailing through intersections while driving carefully on Nokian Hakkas. My wife would refuse to drive the minivan and would take the Land Cruiser instead, because it had far better traction in every aspect. This tire is an unreal winter tire:
I know - I ran it for about 12 years in every possible condition and it vastly outperformed the so called winter tires. I even took a vid with a camera pointed right at the tire to show how it holds and sheds snow as conditions change. Watch the end - that’s a stop from 25 mph on a 8-9% grade.
If you know what you are looking at, you’ll see a tire that is holding snow and shedding it exactly as you want as depth and conditions change, relying on a very narrow center section harder surface conditions, and with the most important feature of all: high and predictable lateral traction. Lateral slides are by far the most difficult to recover from, and most modern tires rely on the electronic traction control system to perform this function.
There is no reason to canonize any specific setup. Studs are a game changer on ice. You can put studs on the cheapest knockoff winter tire you can find and that tire is still an equal to the most expensive highest tech studless tire on the market.
And so here is the slippery slope
:
Why are studless winter tires good enough when they aren’t the best? Because if that argument holds, then a winter rated all weather tire isn’t good enough? Then what is the rating for?
Here’s a little additional rub. The Clear Creek sheriff’s office is smack in the prime I-70 ice corridor. They use Chevy Tahoe’s shod with Goodyear Duratracs. These are your first responders. I wonder why they choose that particular winter rated tire? They aren’t cheap.
