A properly driven Rubicon Gladiator with Falken Wildpeak AT3W tires at about 30PSI is AMAZING in the snow and ice.
If you want better winter weather traction, you need a set of dedicated WINTER tires.

Recovery gear is not an area to pinch pennies. Buy good gear that you trust.
Working Load Limit (WLL) is always clearly legible on quality gear. However, the standards are meant for the overhead rigging industry not winching a Jeep.
So if you want shackles, snatch blocks, etc. that are tested...
I tell people to avoid roof loads, weight up high is no bueno especially when hammering it offroad.
A good spare and a good tire repair kit is all I’ve ever needed in many years and thousands of offroad miles. And don’t forget a HiLift.
