Okay, I ordered the Lezyne Classic for $60.00 shipped from here. I got it today and it works great so far. The gauge says that the front tire is 20 PSI and the back is 35 PSI. That seemed low to me. My tires are Giant S-X3 700x32c. It says that the max PSI is 65. Should I inflate to the max? I weigh 185 lbs. What PSI should I inflate to using these tires? Using the calculation posted by rebel1916 I should do..

Tire Width=32: Pressure(psi) = (0.17 * Rider Weight in lbs) + 41.67

works out to .... (0.17 * 185 ) + 41.67 = 73.12 PSI.

This is more than the recommended PSI it says on the tire.
