AFAIK, Sumitomo by way of TBC has the biggest distribution outside of Wal-Mart and Costco by means of Big O Tires/Midas and a few others. I didn't know Michelin owned a distributorship, I was under the impression that retailers with enough clout *cough* Costco *cough* or a dealership via Tire Rack's OEM side(Honda) or Dealer Tire(Toyota) ordered Michelin or other brands directly from their warehouses.
