2004 Ford Explorer Sport Trac Question: front tires are wearing off one inch of tread on inside of tires
Answer #1patrick mannion from Greg Solow's Engine Room, August 15, 2011, 21:12Master
If both outer edges of both front tires are worn it would be a sign of excess "toe in" of the wheel alignment. Basically both front tires are going down the road with the front edges looking inward too much. Have a wheel alignment done perhaps the tire shop you have used have not had there equipment calibrated recently. The alignment figures should make it obvious if there is a "toe set" issue, or camber issue.
