Oldsmobile Ninety-eight average tire pressure is 29.97 psi. If it is tough for you can round it 30 psi for all 4 tires.
A common situation in which you'd change Oldsmobile Ninety-eight sizes is when buying winter/snow tires. Retailers often recommend moving to a smaller wheel and using a tire with a taller sidewall, without increasing the overall tire diameter. This creates a longer footprint, also known as contact patch, where the tire connects to the ground. A longer contact patch can help snow traction.
