Uneven tire wear on fixed gear PA32

[Flying_Monkey]

I have a fixed gear PA32 and the left main has some uneven wear. I am replacing the tire and tube. The service manual describes alignment procedure for the main landing gear only if the retract version and not the fixed gear version. Does anyone have any idea what we should be troubleshooting for this wear pattern? Doesn’t seem normal. Service manual lists uneven wear under troubleshooting with the cause of too low pressure. Just wondering if there is a toe in toe out procedure for the fixed gear? Thanks!
The inside closest to fuselage tread is the worn side.
