These bolts are meant for use with many ice racing organizations in their "spec stud” class. Specs:

• M8x1.25 bolts (metric equivalent to 5/16”)
• 1.25” long
• Class 10.9 (metric equivalent to grade 8)
• Each bolt comes with a washer and nylon insert locknut for the outside of the tire.
• Flange head bolt doesn’t require a washer on the inside.

• Figure out how many studs you’re allowed according to your organization’s rules
• Pick out a tire with well-defined tread blocks; it’ll make creating a pattern easier
• Drill 3/16” holes from outside in for each stud
• Put a dab of urethane windshield adhesive on the end of a stud and use a drill/impact to push it through
• Put a small bead of adhesive all around the outside of the bolt where it comes out of the tire
• Add washer and tighten nut. The washer should squish the tread pretty well on the outside; it should feel pretty darn tight

There are a lot of factors to consider when choosing a tire for ice racing. We believe the ideal tire has a stiff sidewall, has minimal tread to not eat up bolt length, and isn’t dry rotting. Something less than 5 years old is ideal. Stay away from racing slicks and non-DOT tires, as they will crack at cold temperatures. Ask us how we know…
