Answer 1

Depends on vehicle weight and tires.    Check with a good dealer in your area.

Answer 2

Use this as a guide, 185/65R-14 the recommended air pressure is 28 psi.

Plus one size is 195/55R-15 with a recommended air pressure of 32 psi.

Plus two size is 205/45R-16 with a recommended air pressure of 36 psi. Note how the air pressure increases with plus sizing to meet the load carrying capacity for the car.

Answer 3

The tire pressure is dependent on the vehicle weight, it is not dependent on tire size. The tire pressures listed for the stock tires still apply.
