The best snow tires BY FAR made are the Green Diamond brand,

I do not know if they have a tire suitable for our rigorous applications (I
don't have time to look it up), but perhaps another listmember can do this
for us.

They ahve the sizes we need, it's just a matter of load capability. I'll bet
they have them.
