Screw It; I’m Making Studded Tires

As the title of this post implies, I’ve gone and gotten myself a pair of studded tyres on the cheap – by fabricating them. Those old Chen Shins I had on the bike’s rims came off without a single stud, but went back on with a ice-grippin’ 104 studs per tyre. Total cost: $12.78 for 250 1/2 in. 8-size screws, compared to $100 + tax for the cheapest pair I could find elsewhere (including the interweb).  My time is valueless, so I won’t put a dollar value on the 2 1/2 hours I spent on the endeavor.  

Drilling, and a lot of screwing-in 

On the road, they are really grippy on ice – like being glued to it, even while riding on an outdoor skating rink! But, since the tread pattern isn’t that deep, it still has trouble in the slush or packed snow. On fresh snow, however, it performs quite superbly! One really can notice the clickity-clickity-clickity of the screws on the pavement, and feel the drag also.

Tyre #1, finished – look at that! 1/4 in of spike showing!

Here’s how I done it:
1. Pulled off the tyres
2. Flipped tires inside-out
3. Drilled holes, from outside in, into the knobs I wanted studs in.
4. Spent a whole lotta time screwing screws into these holes, inside to out.
5. Turned tyres back to right-side-in
6. Got duct tape, and covered all the screw heads with multiple layers of tape to prevent puncture
7. Re-install and re-inflate. Be careful – it’s like wrestling with a rosebush!

Mounted and ready to roll!

I plan to get at lest 100km on the tyres this winter, if for nothing else but to measure the longevity of the screws.
