Update Problem solved(i hope), the alignment was way out, 4.2mm out, each side, so total over 8mm! No wonder it was "feathering", as they call it They aligned all 4 wheels for free, but would not do anything about the tyres being worn unevenly. They say it is only covered under warranty if it was detected withint the first 1000ks, come on toyota, hows any tyre going to show problems with that little ks on the clock. Oh well, my suggestion guys is if you think it is not wearing properly, insist on an alignment for free. $88 normal price for 4 wheel, which was done in house, so i have a copy of the report. Ill see how the tyres go now that this problem is gone, they also recommend alignment every service, wow, service is $150, add $88, thats not on...unless it was 20ks between intervals...
