Well I'm not 1000 bucks sure that they will be better.
I have tried so far...22" V-grabbers with screw in ice racing studs, 22" cheng shins of some variety with screw in ice racing studs, 22" Sand Sharks, 4 snows, and the current winner...22" Realtors with snowmachine studs with backers.
I acquired a brand new set of 22" Realtors this year and plan to triple the amount of studs. I forsee a problem with the meat of the tire tearing out when a stud really catches on something. I ran with 18 studs per tire last year, only one per space between the paddles. I could at any time, on any surface break the back tires free. It's a blast to ride and out on the ice track I could drift it like crazy.
My plan this year is to go two per space, and one alternating outsides. The ideal tire option I feel would be a 25" Realtor with two studs per paddle. Keep in mind that this isn't for an ice racing setup, this is strictly for my own amusement out on the lake where my ice fishing shack is. I want to have enough traction to pull wheelies.
I don't think that the weight will be an issue. My V has a 700UTK Fundy, Muzzy, VDI, EHS, VFJ clutch, 4" swingarm extension, etc so spinning that extra weight, especially in the snow, will not even be noticeable.
Thanks for the opinoins and comments, it keeps me thinking.
