I bought this tire to replace a VEE brand studded fat tire because it wouldn't stay on the rim.. This tire stays on and the studs are still in good shape after one winters use on streets and sidewalks. Totally happy with the grip with my motorized fat bike. I am legally blind and this is the only way I get around. I will certainly buy this one again.
I use this for icy conditions when riding around town. The studs really grip the ice, I can even ride (carefully) on glare ice. They are not bad in deeper snow, but I would go with the Dillinger 5s for max float in deep snow.
I never rode in the winter before so when I got my first fat tire bike I thought this would be a great opportunity to give it a try. I always thought of getting studded tires and now I am glad I did. I'm very impressed with the performance of these tires. I felt very confident riding on both snow and ice. I would highly recommend these as a great tire for winter riding.
