Just bought a 2014 Outback 3.6R with 73k km. Continental summer tires 225/60R17 with minimum tread remaining will be replaced with new Goodyear Wintercommand tires shortly (next summer new summer tires will be installed). On dry roads, when driving at low speed anywhere between 5 mph and about 45 mph, the vehicle may drive straight but at random pull left or right (without acceleration or deceleration) . If it pulls one way it can then change and pull the other way on its own. When it pulls it's quite pronounced and requires steering wheel correction otherwise vehicle would cross lanes quickly. Tire pressures were uneven and under 30 psi but then adjusted to 34 psi front and 32 psi rear but the pulling still occurs at random. At highway speeds the car tracks straight. Maybe the existing tires are defective and the problem will disappear when new tires are installed. Any thoughts on other items that should be checked?
