Yep. Winter tires stay soft at lower temperatures increasing static and dynamic frictions in winter conditions.

Extreme doubt on strong enough. The author of this article barely understands the words they are using. Cool it strain hardens, so do so many other materials. Cool it’s tough like many other materials. Wow it has more links than others. No actual numbers about toughness, yield, ultimate strength, cycle limits, etc. It’s great research, but it absolutely isn’t going to magically solve the space elevator issue.
Totally incorrect for both posts. A geo with winter tires is better in the snow than a truck on 40 inch mud tires. Winter tires feel like turning on the cheat codes when it’s slick. They have like 10 times the grip of good all seasons below freezing.
I drive on unmaintained roads a lot in the winter. The hakkapeliittas on my truck let me drive in 2wd until the snow is a foot deep.
Any company will market that its ideas are possible. The article you linked is promising, but take it with a huge grain of salt. They are moving the goalposts the whole article. Flat graphene is a great material for space elevators, but it can’t currently be created without defects. Polycrystaline means the graphene created includes defects sort of. It means the graphene they created that is km’s long has shitloads of places where cycle loading will cause it to fail way under (like 10%) of its expected load carrying capacity.
Edit: I want this technology to exist. My MS in mechanical engineering focused in materials science tells me we are quite far from it happening.
