How Much Air Pressure Should Go in a Pirelli Scorpion Tire?
Manufacturer recommended air pressure for Pirelli Scorpion tires is generally 2.2 to 2.5 bars, which converts to 32 to 36 pounds per square inch. The working pressure needed varies with the tire size in relation to the load, the type of car, the total weight and the conditions of use.
Never operate a vehicle using Pirelli Scorpion tires with the air pressure below 23 PSI. Driving on under inflated tires places too much pressure on the sidewalls, which can cause the tires to rupture or become unseated from the rims. The tire's temperature also affects the PSI needed. Preheated tires need slightly less pressure than cold tires.
