Not to start anything....but...no one has said it yet....mud tires + rain + speed = wreck. Increase your interval, slow down. Sorry man, I know it sucks, but the fact remains that mud tires are lousey in the rain, I drive like a old lady in mine when it rains.
Don't get pissed, just had to say it.
Hope it works out, and she don't sue ya.
