Alternatively, buy or borrow a tire pyrometer. It is used to measure the temperature of warmed up tires (after driving for a little while, at good speed, say over 50mph)

Once the tires are warmed up, measure the temperature quickly in three spots on a tire, center and the edges where the tire still touches the ground. If they are inflated correctly, the temps will be almost the same. Lower temps on the outside, means you are overinflated. (Because the edges aren't touching the road) Takes practice, but you can get the pressure to be pretty finely controlled for each set of tires you have.

36-38 front, 36-40 rear, depending on preference.
