45 North. They are a QBP brand.
Here is a link to there "mission statement"
Perfect, those look gnarly.
I simply run an aggressive mud tyre in the winter. The (discontinued) green Michelin Mud tyres were awesome. This year, the Vittorias that I have seem to be working okay. Honestly, I used to run Ritchey Speedmax semi-slicks, and those worked surprisingly well. I don't know if it's just that I'm used to riding in the snow, but aside from riding on the ice, anything with aggressive knobs should work well.
I agree. Last year I ran Speedmax's and they worked great. Especially nice was mine were the 40c so I had a bit extra girth. Conti Speedkings also worked pretty good, too.
On the monster crosser I had Ritchey Zeds but at 42c, a bit bigger than most bikes will accept and no longer on production.
Update- Just to follow up. I ended up buying 45 North's Polara Studded tires. So far they work great. I ride on unplowed ice covered farm access roads, that have icy off cambers (that are hard to even walk on). With the Polaras I have no problems at all. I try to get them to wash out & I can't. I have several hours on the tires and only lost 2 Studs, 1 in the front 1 in the back. The studs are replaceable. Not bad for $50. Some places have them for $41. 4 out of 5 stars. I'd recommend them to a friend.
Oh, interesting. What would make you give them 5 out of 5 stars, out of curiosity? Those are cheaper than my normal CX tyres, and with replaceable studs, it sounds like you can't go wrong.
Hey, Sorry didn't see this till now.
I usually don't give 5 out of 5 on anything. I guess if the tires were lighter (@ 886g lighter then most) environmentally friendly and had carbide studs, but that would sacrifice quality & drive up price.

I really liked my Schwalbe Marathon Winters for winter commuting. I would have gone with Conti's tire if I could have fit it under my fenders.
Michelin Mud 2s worked really well for me in the annual "Snow Bike Race" here in Buffalo (off road).
