Uneven tire wear

[HUMMERICH23]

Ive got the same issue with my cognito level with 37 Stts with the front passenger tire wearing way premature compared to rest. Have had alignment checked three times and it is dead accurate. I get wear on outside lugs and 1st center traction zone closest to the outside lugs. all the rest of the tires are showing perfect wear. I cant figure it out too, unless its just normal wear for the front passenger tire?
