the tire pressure or psi for engine compression?

tire pressure should be around 32-35. never fill according to the side of the tire. that is the MAXIMUM the tire can handle. you always want to be above 30, but not more than 40 unless the car is fully loaded up

the engine compression PSI, depending on the engine, should be around 140PSI. if one cylinder is around 100 or less, you've got a problem
