For wet roads, it isn't so much the width of the tire that is the problem as is the design. To dissipate water, you want a tire with a high void/tread area ratio. This give the water somewhere to go, other than under the tread. Also, some tread patterns more efficiently remove water for a given void area than others. This is the rational behind unidirectional tread patterns (like the ones used by the Bridgestone S02 and the Michelin Pilot Sport, among others). None of the tires I've seen standard on a BMW, short of the Pilot Sports on the M3, seem anything to write home about. A tire upgrade may solve your problem.
About Rain-X. Very intersting stuff. But not without its flaws. I used it a couple of times. In the rain, you better off not using the wipers, especially at night. With the wipers off, the rain just rolls off the windshield without obscuring the driver's view. However, with the wipers on, the water leaves a streak as it is wiped, which can be quite annoying, since it picks of headlight and streetlight glare.
: Like the previous post, use Rain-X on the windshield. Your wipers will work better. Althought don't put too much of that stuffs because it will leave some haze. But you can take the haze off with Windex. Also, I clean my windshield every 2-3 days because the wipers works better on the clean windshield.
: As for hydroplanning, it is the width of the low profile tires. They are not that good on wet surface.
