LONG POST WARNING:
I've tried tire shop siping on the original KMs a few years back. Didn't get any result in icy driving, but the tires did chunk out A LOT faster and I only got about 25k good miles before I had to get a new set.
Since then I've tried actual snow tires and the siping is great, but the real impact is the low temperature softness of the rubber compound. I've been driving CO winters for 16 years, back and forth from Denver to Summit County and I'll tell you from direct experience nothing, NOTHING, compares to a dedicated snow tire in an emergency stop or avoidance maneuver.
I'm admittedly an old man driver and am cautious to a fault, but other drivers are not and I've been saved at least three times over 5 years from catastrophic accidents thanks to my dedicated snow tires.
Now from a cost/benefit standpoint some might not consider 2 sets of snows over 5 years worth the opportunity cost of other Jeep mods. But when the rubber meets the road (pun intended) i want my money invested in two sets of tires, one for the off road adventures of summer and one for the nightmare of driving with idiots in their Mustang on i70 in a blizzard.
