That is killing the tire. If you need to run like that to prevent spin, you need to work on the chassis. Can you give us more info on what was happening when you dropped the air pressure and improved sixty foot time? i.e. spin, hook then spin, turn the tire then hoook, etc. Just the number doesn't tell enough of the story.
