imho those are going to be great tires for a year round DD, and if you run a 2.5 " off set, that might be a little to much for daily driving, if you run about a 3.75" off set, they should just stick out the fenders a little, that way you wont get buged by the cops.
i run a 15x7 with a 3.75 off set, and 30" tires, and they are flush with the edge of the fender, maybe stick out about 3/8" i have lots of room between the tire and the frame at full lock, about .5"
when i had 235/75/15 tires on the exact same rims you have, they rubbed at full lock.
another good tire for winter is the BFG A/T TA's and something simular is the general grabber at2, but its alot cheaper.
