Why is it that snowblowers do not have real ice/snow tires on them from the factory? All the snowblower tires I have seen have tread designs that look like they are made for mud, not snow and ice. I have not seen a snowblower tire tread design that looks anything like that on an automotive winter tire. I may just put some carbide studs in my snowblower mud tires. But at over a dollar per stud, the cost can add up fast. The tires on my 24" Sno-Tek dig through the snow satisfactorily, but when they touch the icy surface below, traction is poor, especially going uphill. Here are some studs I found with a search. http://www.maxigripstore.com/maxigrip-ice-studs-hm11/ Anybody here use studs on their snowblower tires? How did they perform? Any downsides other than cost?
