If you run the DOT race tire, or Slicks, and it rains, you will have no fun on the track. That's where rain tires come in! The Bridgestone rains offer incredible grip in wet conditions for racers wanting to maintain an advantage in adverse conditions, or track day riders who want to continue going fast despite wet weather. If you've never ridden on a rain tire, you won't believe how much grip can be had in the rain! Not for use in dry conditions under any circumstances, they will burn up in a very short time if ran in the dry.
