None of those pictures showing cupping just left side wear. Maybe another thing altogether than the picture in the OPs post. Many miles and many tires, most wear centered, very few did not, some did show cupping at the end of life but all were on the same roads over the years. I do believe left hand turns can wear the left side more than the shorter right hand turns and that improper pressure (under40) can increase wear. I think road crown plays little to nothing in how a tire wears. Google left hand tire wear, most, bike places, mags or someone with supposedly some expertise say it is a myth but many individuals on forums still throw it up as a truth. The OP pic is an extreme example of this scalloping problem and I bet has been run with very low tire pressures. TWO WRONGS DON'T MAKE A RIGHT BUT THREE RIGHTS DO MAKE A LEFT. That might help your tire wear more evenly
