You mentioned in your first post these tires were very undersized - they look fairly correct to the naked eye and look a lot like my '06 LX with 18s and Defenders. What size are these?
I had my one year old Michelin Defender LTX M/S with 8k miles on them rotated and road force balanced, and...I think it helped some.
