Kold Kutter screw in studs in Coleman mini bike tires, mounting, testing and evaluating

Ice everywhere! A great opportunity to test a different kind of screw in stud than I used last year. The Coleman tires have a shallow thread so I could not use a long screw in stud and I am a bit worried that they wont stay in the tires. Me and wife take a short test ride to the nearby lake for some Swedish fika and then I do a short evaluation of the studs.
