My wifes Dodge Caravan's driver side rim gets REALLY hot after long drives (1 hour or so). It smells of burning rubber (the tire perhaps?) and when I put a drop of water on it, it sizzles and evaporates in about 3 seconds. I just replaced both drums and pads on the front tires and I thought for sure this would fix the problem. The two front tires are also new. Any idea what the problem might be? I don't hear any squeeling or grinding sounds when driving. What can I look at?
