4wd with snow tires should be fine. I doubt you'll see
R-3 conditions.

Chain Requirement Levels and Traffic Control Definitions
R-1: Chains or snow tread tires required. Snow tires must have a tread depth of 6/32" with a "M & S" imprint on the tire's sidewall.
R-2: Chains required on all vehicles except four-wheel drives or all-wheel drives with snow tread tires on all four wheels.
R-3: Chains required - ALL VEHICLES- no exceptions
R-1 and R-2 are the most common chain controls. The highway will often be closed before an R-3 control is imposed.
