Road slush will build up on my Honda just up to the point where the tire won't let any more accumulate. Based on this and all the other cars I've owned over a lifetime of driving in The Great White North, I just don't see it being much of an issue. My guess would be that a couple of whaps with your gloved fist would take care of most of it. NSTG8R, never knew about that stuff. I'll give it a try next winter.
