Tires look under inflated. ST tires that are more than 3 years old should be monitored very closely for abnormal wear, an out of round condition, or lateral shoulder variation.
You can quickly validate axle alignment by placing a straight edge against the sides of the tires on each side at the center of the wheels. The front shoulder of both tires should not touch the straight edge, because the wheels should have slight toe-in for directional stability. An eight foot long floursent light tube can be used as a straight edge.
Travel safe. Pat
