Those tires work with the pressure you have in them and even more. I run them in the 18-24 range depending on the car. One car runs 1.38-1.40 60's and 10.40-10.50's.
DO NOT do a huge burn out. Short, quick hit to clean them off. They tend to get greasy if you hit them with a long burnout. If you can drive around the water and back into the wet area. That's a decent method to keep from picking up water and slinging it into the fenderwells.
The front end is the place where more time is hidden than the rear.
