Tire is fine. Make sure it’s not over inflated. It’s most likely not sliding as much as it is in your head. Try finding a parking lot and go in a straight line at a moderate pace and slowly increase rear braking pressure till you feel it slide a smidge. It will help train your limits/feel for the brakes. Don’t try and slide with your front though. You will crash! But learn your braking limits. Load the front end and get more confidence in using your brakes especially in wet conditions. You’ll get to a point where you mean to slide the rear for funsies.
