This time around I'm using a new product at the shop made by GripStuds. They make individual studs that you can install into almost any bike tire. Their studs are made from Tungsten Carbide (same stuff they make drill bits out of) and are very durable. So, if you have a certain tire tread pattern that you like or an extra set of tires laying around, these studs would be a good choice to get your winter riding on. For my project, I used a set of tires off a Surly Pugsley since no one seems to make a set of studded tires for it.
As with most projects, planning is key. GripStuds recommends at least 50 studs per tire. They also recommend that you use a scattered pattern and not just install studs in a straight line. One last note, studs are best suited on the cross section of the tire (the knobs in between the center of the tire and the very outside or shoulder knobs. You want your studs to make contact with the ground from several different angles. With these thoughts in mind, I grabbed a silver marker and started putting a dot on every other cross sectional knob. My pattern gave me 100 studs per tire...fitting number since the Pug tires are 3.8" wide!

After my knobs were marked, I took a punch and stared a hole for each stud. Now GripStuds says that pre-holes and drilling are not necessary. However, with the small size of the knobs on my tire it was imperative that the stud start right in the middle of the knob and not stray off to the side and tear the rubber.
With holes all punched it was time to start installing the studs. GripStuds makes a handy little installation bit for your drill. Sweet. And each little stud has two slots on its shoulder, think slotted screw driver system. I found the engagement of the stud and tool very positive and easy to use.

Patience!! I cannot stress enough that you must take it slow. Set your drill on a slow speed and use alternating power to ease the studs in. I always had to keep an eye on the stud to ensure that it was going down the center of the knob and not veering off course. Once the stud was set down to its shoulder, I moved on to the next one.
It was super slow, but the finished product looked great!
Note that as opposed to the sheet metal screw install, there is nothing protruding inside the tire casing. Long wear life, ability to remove/replace studs and shallow penetration make these studs a great choice for your winter tires. Wanna know more about GripStuds? Check out their site or hit me up.
