Spikey Tires!!

Doug called me the other day and said he never knows what I am up to in CO cuz I never post. Well, it will be a bit before I can update for what I was doing in Janurary, but I can at least tell this story.
Thre are 18 of us headed up to Steamboat for 4 days of skiing. They are also having a winter carnival up there and one of the events is a mt bike dual slolam race on the ski slope. So I heard that best way to stay upright was to put some spikey tires on your bike. Too cheap to by some real ones, I made some. I tested them a bit on the frozen snow patch by my house, I think they will work pretty good. The race is Thrusday night, so I will let you know after the weekend.

On the single ply tire I could turn it inside out and put the screws in pretty easy. I just picked a random pattern that should allow at least one screw touching the snow at all times. I would prefer more, but that would be too many screws and too much weight. This one will be my rear tire.

Bling Bling 2.35 for the rear. One of the trashy tires I had laying around.

Insert a liner so the screw heads don't cut the tube. The liner is an old tube sliced open.

Slide the tube inside the liner.
The front tire is a Swamp Thing 2.5.

This is Front tire 1.0. I felt it needed more traction so I added another row of screws on each side.

Front tire 2.0.
In the end, I used about 160 screws. About 100 in the front and 60 in the rear.
