Ice storm, ice ripper, ice attack, ice cobra....some tracks now come indexed for them too....igrip and bergstrom both carry the screw in studs...Yeah but no one uses screw in studs on a snowmobile that I have ever seen. Yeah used them on quads and dirt bikes but never a snowmobile.
What model and year did you get her? Also 1" studs for a .91" track and 1" is the biggest you can go with a liquid cooled with the front center radiator being right there.
Totally understand that the factory ones are most likely better....if a screw in one would bend I believe it would be the same fate of a factory one. I do agree the screw in may come out easier, especially if care was not taken to put in....but think for a second realistically(im not trying to be negative or disrespectful towards you at all), a tire rpm is going to be a lot faster than a track rpm, hitting same crap if not harder than snow conditions (like rocks, roots, hard ground)...Im not too worried either on the tunnel...its a 550 fan!Those are not screw in studs, that is a completely different setup. The tracks are molded around the stud and they work well.
When you say screw in studs these are screw in studs. Never seen them on any snowmobile in the midwest in 42 years of riding. Now the quads, dirt bikes and cars that race on ice...yeah all day long. I wouldn't put those kind of studs in a track with it spinning like that and the possible bending of the lugs. Too easy to rip out.
