Drkangel,
Here's a sketch of what I had in mind. Based on a misunderstanding, but I like the idea. Without 'tire' liner on the left, and with it on the right. This summer I'll try and find a suitable knobby tire- smooth tire 'liner' combo. (The OD of the inner 'tire' has to be just the diameter of the inside of the outer tire.)
Under torque, the screw rocks, pivoting where it passes through the tire cord (the dotted brown line). This tends to wear and even tear the tire lug where the screw passes through, as well as wearing the tube and inner surface of the tire. Using a cut down tire for a liner, the 2 cords are a distance apart and will absorb the rocking motion as linear force applied to the cords. I would expect it to almost eliminate rocking. And if the screw head wears into cord, it will be the liner's.
I don't want to deal with the slime when, not if, I have a flat.
I expect that multiple thin tubes with powder between them will work better than one thick liner or a thick tube for minimizing wear from the screws (the liner will slide instead of trying to resist any screw motion). If I found a thick, non slime, tube (had one in my bike 50yrs ago), I might try it, but don't think it would be better than multiple tubes. You folks that ride 10,000 mi a year might get tube wear where the liner ends, but I tend to have flats for non wear related things (nails, steel scraps, glass) often enough to allow inspections. :wink:
If you ride long distances on pavement, I expect you should leave the middle unpopulated and use high pressure so the studs only touch when leaning, and even then they will wear (and possibly skid). These screws are cheap and easy to replace (once you get the tire off). Kold kutters are easier, at least if you do it before the head wears off, (in which case the threaded part can work it's way in and cause flats).
I chose the stud setup in the picture on the last page BECAUSE my conditions are unusual. All winter I ride on ice, packed snow, or sometimes loose snow, and almost never on bare pavement. I wanted something that could grip the ice when there was a thin layer (1/2"+) of snow on it, and help when it was thicker. I've been impressed beyond expectations.
Pavement with ice patches is a whole different story.
Next year I'll have a 17" motorcycle wheel on the rear and hope to find a tire I can mount these on (a worn till it's 'flat' knobby?).

Replacing the bolts with these (or equivalent), as well as in the spaces between the claws.

And putting these between the knobs along the outside.

I have them and wouldn't have to order, the links are just examples.
Edit: found the shorter ones (11mm). Expensive, and still plenty long.

It got down to -28F only a few days ago. This has been the longest, coldest winter I've ever seen, and I've been here over 30 years. My guess is we had an average temp of -10 for the last 6 months. I've tended to ride less often, and for shorter distances this winter.
