OK...
It's my plow truck (04 2500 HD 4x4). Stuck way too many times, sliding all over the place yesterday. I actually had to shovel twice (once was my fault, no tires would have gotten me off that tree stump!)
I'm going to go with some much more agressive tires... My OEM ones are almost done anyway (and I have a second set of OEM tires to use in the summer anyway), so any suggestions for a good, very agressive, snow tire?
