Just completed my first DIY studded tire. I'm very satisfied with it. I used a pair of Bontrager tires that were the stock tires on my mtb. Took them off right after I got the bike and they've been lying around my garage since 2004. Bought a box of screws from the hardware store for $3.49 and off I went.

Drilled a tap hole through the tire from the outside. Installed the screws from the inside. The LBS gave me a couple of old tubes that I cut and used as the liner between the screw heads and the tube. There are 32 screws per side on the tire. Looks great. I'll see how it rolls when the snow hits around November.

Sixty Fiver's previous posts with explanations and photos helped a lot with this. Thanks, SF!
