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. |
Wow, you're good!
