As far as Tires go, It's your choice, go with what feels right. I personally like to buy from "local" chains (which tend to be a bit more expensive) to help out the mom and pop stores. Wal-mart makes enough, help out the little guy. As far as Ice and Rain go, some tires work well, some don't-If you expect those conditions then select a tire properly suited for that work. Keep in mind that Jeeps are more or less designed for an X/C (cross country) nature by design. There is not a lot they cannot handle unless set up for that..(rock climbing...) Your jeep will treat you well. It all depends are what your looking for and what you intend to use your machine for. All the best.
