This is a mistake lots of people make. The pressure marked on the tire is the maximum set by the tire manufacturer -- they put that on there for liability reasons, so if you burst a tire you can't blame them. The actual recommended tire pressure depends on the vehicle weight, and is set by the car manufacturer. It'll be in the owner's manual and often on a decal in the driver's door jamb. It's usually well below the 35psi maximum marked on the tire. If your tires are over-inflated, they won't conform to the road properly and your road-holding will be reduced, sometimes enough to be dangerous even at 35 psi.
