Peterbilt 387..wearing outside shoulder on passenger side steer
I have a 2006 Pete 387. I have been having consistant trouble with the outside shoulder wearing off on the steer tire. The driver side tire is good and gets good mileage out of with only slight inner shoulder wear. This problem starts slow, meaning it doesn't show up till about 25-35,000 miles. Once this mark is hit the wear becomes fast and aggressive. the rest of the tire treat is good and by the time the outer rib is gone the center and inner treat is still over 50%. I have had several alignments and they all come out good with only minor adjustments needed. I have also kept a close eye on tire pressure.
I have checked all the easy and common areas I can think of and am at a loss as to what to do now. Any help anyone can provide me I will greatly appreciate it. Thanks, Nate
Is this a worthwhile discussion?
