On smooth surfaces like the one used in the tests shown above, moderately high tire pressure – say 100-110 psi for a 25 mm tire – actually rolls slower than either a lower pressure (80 psi) or a higher pressure (130 psi). On rough surfaces, higher pressures roll significantly slower. ... and you have found the optimum pressure for your ...

For example, if your blood pressure is "140 over 90" or 140/90mmHg, it means you have a systolic pressure of 140mmHg and a diastolic pressure of 90mmHg. As a general guide: ideal blood pressure is considered to be between 90/60mmHg and 120/80mmHg; high blood pressure is considered to be 140/90mmHg or higher

In the 1980s, national guidelines set normal at anything under 140/85. Today, a healthy blood pressure is under 120/80. People with high blood pressure are urged to get it below 140/90; those who also have kidney disease or diabetes are urged to go further, with goals under 130/80. How far under remains to be determined.
