Wider tires = worse for rain?
So my thinking is that wider tires gives more contact patch which makes for better dry traction. However an article I read in an old Sport Compact Car (AWD wet/dry racing of some sort) overly wide tires become "boats that cars slide around on" or something to that effect.
OEM tire sizes (205/60-15) make for a contact patch of about 35 square inches (7in x 5in). I'm running 225/50-16 in the front with a fat 88 square inches of contact patch (8in x 11in) and in the latest rain I've found that I am much more prone to hydroplaning at speed. I didn't have problems like this last year when I was on factory size tires at all four corners.
Is this because my tires are much wider/bigger contact patches, or is wet traction decided solely by the tire design itself (grooves, channels, etc)?
