This may be a really dumb question, but for the OP's issue, would having I higher tire pressure on the driver's side to keep the wrinkling at a minimum and a lower pressure on the passenger side help him out at all? I haven't heard of anyone doing that but it came to mind.
If you had a spool, it would pull to the right, all the way down the track. If it was a pos, it would cause excessive wear on the pos, and may still pull. Air pressure needs to go up and down evenly.
