Winter won't be boring!

Push through snowmobile studs would be much simpler and quicker (though more money) than using standard screws and sharpening them. The biggest issue would be clearance to the swingarm and chain. Have to do some serious measuring of clearance, as carbide tipped studs would make short work of an aluminum swingarm. So far the shortest studs I've seen are 0.700" long. That would clear the swingarm at a standstill, but tire growth at speed (particularly with the added mass of the studs) would probably eat up clearance.

A smaller rear tire might help, but I doubt that they would work on the 5.5" or 6" wide rear rim of most modern sportbikes.

Back to the drawing board...

would you be able to put a spacer on the inside of the tire?, that would shorten the lengh they stick out

then you risk the tube

I was thinking that myself. It would depend on how thick the bike tire is versus a snowmobile track. Based on how thin they feel (at least once most of the rubber has been worn off), I'm thinking they are thinner. If so, then you could probably add some washers between the head of the stud (push through type), and still have enough of the threaded stud sticker through the tire for the nut and backer plate. That way you may gain 1/8 - 3/16" clearance.

I don't think this would cause an issue with a tube, as you would probably still use an old tire carcass inside the tire to protect the tube from the studs. That plus the fact that snowmobile studs have a pretty smooth surface as the idler wheels need to roll over them in a track.

I wonder if you can plug a bike in the winter...


Just joking

I am sure tubeless is out of the question (its gonna have 1000 holes in it), an old tire as a spacer will work easily and if you want to protect the tube just use an old tube as a liner(protector). We used to do that all the time, but with all the power and twisting I commonly go thru 2-3 tubes a season.
