Recently, I had all four tires replaced with Bridgestone Dueler H/L Alenzas and just had them rotated after 5K miles and noticed that the outside tread was feathering and the inside tread was wearing excessively. The center treads seemed ok. Is this an alignment issue or a suspension issue? I only have 60K on the truck with city/hwy driving and no towing. I did have the rack & pinon replaced under warranty just before the tires were replaced. I also had an alignment done when I had my tires replaced.
