Hyundai Santa Fe 2010: Solution for tyre wear issue?

Regarding the Hyundai Santa Fe owner whose car was wearing tyres, we had a customer in recently with the same concern on an R-series Santa Fe. Repeated checks with our wheel aligner, and also a specialist tyre place, failed to find any abnormalities. I was all within spec, but after a thorough investigation and tests we found the rear toe required adjustment. Specifically, the left-hand rear had too much positive toe, and once corrected the vehicle drove well. We have advised Hyundai of the outcome?
