Check out Cooper ST's or STT's. Can't say that I drive in the snow (live in Louisiana) but they are available in the size you are looking for and look like they will provide excellent traction.
What makes you say that? I found all kinds of tires on Tirerack.com with the 275/70/18 size including the Wranglers I use.cneary812 said:Those tires were made for the pro 4x and you will not be able to find them in that exact size for some time (nobody makes that size tire yet) but you can get that diameter tire easily.
