It it common for a 4Motion Passat to hydroplane easily? I purchased this car used with Cooper Trendsetter SE tires with about 75% of their treadwear remaining. I originally intended to replace the tires, as they're not performance tires, but I was so impressed with the handling that I decided to keep them. However, the car has hydroplaned several times this week on the interstate in heavy downpours. I don't know if it has anything to do with the 4Motion, but it seems to easily hydroplane over 50mph, I've noticed several times that it feels disconnected from the road, and when I applied the brakes, the ABS went wild for a few seconds before the car began to stop. This is really confusing for me, as the Cadillac that I have driven for the past 9 years has never hydroplaned on me, even at 75mph in a downpour. My Cadillac weighs 3500 lbs and has 215/65R15 tires, so the Passat is about the same weight, but the tires are a little wider, but I didn't expect it to make that much of a difference. Is this something that is common for 4Motion Passats, or is it just that I have tires with an extremely poor tread design for hydroplaning resistance? If so, does anyone have recomendations for a good high performance tire that won't hydroplane every time we get a heavy downpour? I've been considering the Continental Extreme contact, but I have no experience with them.
