Wheels with real good traction

I don´t like chains on the wheels so I decided to try something else. I was able to get some old and used rallycar tires with spikes. Not all spikes are left, but many enough for my use on the tractor I cut the sidewalls of the tires and took a pair of wheels from Volvo Amazon. Well, the center is from the Amazon and the rest is a thirteen inch rim, welded together. The tire is attached to the rim with self-drilling screws. The traction on ice and snow is superb.
