That C-rating is what made me skip over the 37's for a set of 38x13.50's. I run them at a cold 35psi, and they translate much less of the small cracks and bumps to the driver seat than the factory 285 ko2's. No slip in everything from that initial misting to full on torrential downpours. My driving habits are middle ground, not racing around and not taking it slow.I like the Coopers over the Pats because they are more flat and feel more planted. They are a little noisier but they are also at 50% where the Pats are around 90% left. The Pats are also a stiff ride if you run them at 30-32psi. Ironically the 38" Pats are a C rating vs. D rating so they ride smoother. I run the Pats at 24psi cold for my wife sicne she has a neck fusion and they are too stiff of a ride above that.
I also don't like the way the Pats feel in the rain. The Mrs. likes them but does note she feels a little iffy in the rain.
