Max pressure is the Maximum ALLOWABLE pressure for that tire. If you were running fully loaded to the max weight allowable, then it would not hurt to add air up to the max. However, for normal driving, max pressure will degrade the tire faster and cause it to wear in the middle (lower pressure than recommended will cause the tire to wear on the outsides faster).
The recommended COLD pressure is obtained by testing by the vehicle manufacturer, in this case GM, at the Proving grounds, along with a Tire rep (Bridgeston or Goodyear in the case of the H3). the recommended pressures allow for an even wear across the tire (alignment allowable), and for the best ride for comfort and fuel mileage.
You will not necessarily damage a tire with max pressures, but it will wear a lot faster due to the center wear pattern.
35 psi is the recommended COLD pressure for the Bridgestones.
