Haha, I do use 4A, but the stock tires are known for their poor skid rating and bad wet performance. The fact it is comparable to driving on black ice on an old truck with bald tires makes me think there has to be a better alternative - and that's while going to a more aggressive tire.
If you want good wet weather performance, you should look at street tires. Offroad tires are designed to excel in mud and rocks, not wet pavement.
