Howdy Thomas.
I am probably running in the same climate as you.
I just switched to Kenda Pathfinders on my 240 Blaster. I am running Banshee rims and hubs.
I have also run ITP MudLites on my KTM Blaster with good luck
These are on Blaster rims.
This is an overly powerful Blaster that relies on float and spin to get over deep mud.
With these swingarm machines once you drag bottom, you are stuck.
You have to float, not dig.
I stuck some short (#6?) sheet metal screws in 2 rows of the edges of the knobs to grab the ice:
This is not enough screws for ice racing but is plenty for braking and icy slopes.
The worst is breaking through 1" of ice on flooded trail and trying to climb up the wet slab.
This many screws will do it. When worn off, I chuck more in.
You need a soft compliant tire to float over the mud and snow.
A heavy tough deeply treaded tire is not needed and works worse, even on a 100 lbs heavier machine.
To get over deep snow you need low tire pressure. I'd suggest 2.5psi to 3psi.
You float over the snow on flat patches of rubber.
Digging to the bottom is no good after 3" on a Blaster.
I have 4-6" in the woods at this time and I can run around on it like nobody's business.
The soft tires and snow suck up a lot of power, but traction is not a problem.
Happy Trails!
