I was always led to believe that cars with wide tires like Corvettes will more easily hydroplane and slide on ice/snow as well. Wider tires have more room between grooves than narrow tires so there is still area where water is not clearing out. Weight is distrubuted over a wider contact patch meaning less lbs per square inch of contact. While road-hugging weight may be the enemy in dry conditions, it is preferable in wet and snowy, and that weight presses down more when there is less contact patch where it is distributed.
For any who doubt this, think of a pick-up truck that most have us have driven. In dry conditions, when you load up the bed, what happens. The truck gets tail-happy, weight and more specifically, weight distribution hurts the handling. In wet or snowy conditions, however, what do you want. WEIGHT in the bed. Otherwise you spin those rear tires like crazy for lack of traction due to low weight on the tires.
That being said, Tony, I did not seem to have too much trouble in the scenario we discussed at SZ between me and the Cadillac DTS in the rain. And my tires are definitely wider than normal at 215/40. Who says Kumho 712s are no good!!!! Kids, DO NOT try this at home!!!!
