44psi is the maximum you should ever have that tire inflated to, when i put tires on and they call for 44psi, i put in 39 or 40 lbs, the heat between tire and groung will heat them up slightly, making them have higher pressure, running tires under/over inflated will damage them and overinflated is very dangerous, and running 100 psi on a street tire is not smart or safe; running the tire at its reccomended pressure is the best way to get the maximum surface area on the ground over inflated tires from the front look like a 'u' and under inflated look like a 'n' but just right and the sit _ wich puts the most amount of rubber on the ground at any given time
