I just bought a 99' Scort with 148,000 miles. When I got the car home, I checked the air pressure in the tires and It was something like 15lbs of pressure. I aired up the tires to 35psi, and now I notice when I turn to the left, the car seems to want to pull really hard after a certain amount of wheel turn. The car acts fine when I make a right turn. Is this the tires or something suspension related?
