So this fall I was all excited to put my 40" Boggers on my K5, only to find out recently what a NIGHTMARE they are when it is slick out (especially snow and ice). The giant width makes them want to go their own way, and because the ground pressure is so low they are always 1 second away from running off the road (or worse). Has anyone had success adding siping to Boggers? Or should I just get a more street friendly tire for the winter? How do you go about siping?
