TSMI tire studs are a tungsten rod about 1/8" thick surrounded by steel about 1/8" thick.

I just took this photo of one:

Drywall screws are brittle and thin and nowhere near strong enough to bother with. Screwing them through the tire from the inside would just result in them getting pushed back through without digging into the ice with any effectiveness, and would leak. It would work for bicycle tires (less weight, more tube), but not car tires.

There are screw-in studs, as Shadow suggested, but they're very expensive, I'm not familiar with their performance (which I assume is decent), and I suspect that they don't meet the legal requirements for on-road stud use.

Motorcyclists that race on icy lakes usually put screws from the inside out, but I'm not sure how that would hold up on the road on and on a car tire.

So, a year later: the internet wants to know what happened with those studs!!

I'm afraid I've got no satisfying answer. :( After continued failure and changes in vehicle usage patterns (that car doesn't commute anymore), the project priority dropped too low to bother with it.

Unfortunately this is not a DenverCoder9 issue, else I could just reply since I'm still here.

That xkcd is great for anyone who has to troubleshoot.

in somewhat (somehow) related news, my tires have redeemed themselves while driving in the snow of the past few days. i even found an unplowed parking lot and had some fun. :) :D :twisted: :!: :mrgreen:

My current rear tires are a disappointment. They are studded old-school Firestone Town & Country tires, made specifically for the rear axle on RWD vehicles.
Image

I had read great things about them and snow posted by multiple people. My previous set of tires, branded "Traction XTC", were incredible and had a similar old-school RWD rear axle tread pattern and didn't even have the heavy siping that's in the Town & Country tread.
Image

I waltzed past stuck 4WDs up hills in storms with those tires. Nobody sang their praises. So, imagine my surprise when the highly acclaimed Firestones with heavily siped tread turned out to be lame...

That tread pattern looks scary. I can see how it might help but my instinct tells me somethings wrong with it. My winter force tires were surprisingly good in the snow, even a few inches.
