^Yes, the wider the tire the more likely you are to hydroplane. I'm currently running 32X11.50X15 and I don't really have much of a problem in the rain. My father has a '97 TJ with 33X12.50's. He says all the time he is constantly spinning his tires in the rain, and his TJ has a 2.5 and struggles to pull it's self. That tells you what a difference 2 to 3 inches can make in control
