Ez sent over his "how-to" on studding up his tires for the Ice-cycle race.

"It was time to stud up another set of tires for our ice race season as I am now racing a 29er.

Tire choice was easy as I wanted to have a good amount of knobs that are well spaced in a 29 x 1.9"-ish and the Kenda Karma 29 x 1.9" fit the bill exactly. In my opinion there is no need to have a wider tire as flotation is not desired but cutting down to the ice is paramount for traction. A good studded ice tire will have better traction than almost any other tire-surface combination as the studs bite in to the ice nicely.

Having procured the tires all I needed was time. For anyone thinking that they will just stud up a set of tires in no time—think again. I invested at least 4 hours per tire. Finding a comfortable seat, in my case the couch in front of the TV with a cycling DVD that does not require constant viewing.

I find Phil and Paul very calming to just listen to, and studding tires smooth and steady is the key to finishing.  I started out drilling small pilot holes with a 1/16 bit from the outside of the tire square in the center of each knob. The holes serve as markers on the inside of the tire to know where to start and guide the screws nicely. This does make small rubber shavings that will annoy any one that you live with so maybe spread a sheet or blanket before starting to help contain them unlike I did. Once the pilot holes are drilled take a break, then start screwing the screws in. 

For my tires I used 8 x 1/2" galvanized Phillips head screws. I think that they are a large enough diameter to have the threads grab into the rubber without tearing the casing apart too determinately. Stainless screws are preferred but can add up quickly $$.

Once you have ignored your family or loved ones/roommates long enough to have installed all the screws, I recommend setting the tires aside and re-entering the world we live in. In a day or two (or minutes before your are supposed to race), take an old tube at least the same size as you will be using if not larger and cut the valve stem out and slice it down the inside to be able to open it up. This will be your tire liner to keep the heads of the screws from puncturing the new tube. It is most convenient to glue the liner in to the tire as to facilitate ease of installation of the tire and tube. I used a can of Rema vulcanizing fluid that I just happened to have picked up 10 or so years ago and never used, to stick the liner in the tire.

I mounted one bead of the tire (especially necessary with a folding bead tire) to an old rim as this can get messy and liberally coated the inside of the tire using at least 1/3rd of the 8oz can per tire. I Let it sit for 10 min to tack up and inflated the new tube to keep its shape and wrapped it with the tire liner. 


After the vulcanizing fluid tacked up I took the tire off the old rim and installed one bead on my wheel and installed the tube and liner being careful to keep the liner centered in the tire. With the tube and liner in I finished mounting the tire and inflated the tube. All that is left to do is mount your wheels and go ride on ice, and ice only as the screws will were down quickly if ridden on paved surfaces."

Thanks Ez.
