Also, that tyre spray ... would be worth trying
Imagine if, every time the Traction Control or Stability Control approached its intervention threshold - just before individual calipers started clapping rotors - and it was 41°F / 5°C or colder, the on-board traction enhancement resin would be sprayed on the tires. That might
a) enhance grip just before and during the typical intervention mode, squeezing more effectiveness out of the Traction /Stability Control Systems
and/or
b) minimize or avoid the caliper pulsing events
It could also be applied by the driver at will, say, just before ascending/descending hills, for example.
(This may lead to a new traffic warning sign being mounted in certain places by the government ...
"Steep Incline. Consider applying traction aids."
Auto manufacturers may also feel the need to warn drivers that their vehicles will not float if the frozen pond they try to drive across shatters, since the resin cannot affect hydroplaning thresholds.)
As far as tires are concerned, I absolutely agree that people should be made aware of the benefits of how winter tires' aggressive sipes, tread/void patterns, and rubber compound are better suited for not only general cold weather, but in many cases, specifically for snow and ice.

However, why isn't it possible/feasible to fit studs to any tire at any time? You can slip on a TireSock, or spray on TireGrip anytime, regardless of tire spec. Of course, you'd wait till road conditions made it necessary. That said,
a) I can imagine an elastic ring, or elastic rings, of tire studs secured around the tire might be at least as effective as a TireSock.
b) Why are only some 'winter tires' studdable? At least theoretically, how would a set of summer or all season tires suffer if they were designed with the ability to accept polymer studs? You'd have the additional option of applying them, or the laissez-faire option of doing what most people normally do
Note that these would differ from option 'a'. You'd go to a [tire] mechanic who'd apply them to tires designed to facilitate a somewhat more permanent fixture of the studs. You'd then either go back to the shop to have them removed, or the polymer studs would simply wear out, designed to expire before the rubber.

I wonder how you all feel about
Tire Cables? (Not Tire Chains; Cables feature much tighter clearances than chains.)
