Short answer: No.
Only 1 Co-Op brand may be claimed for 1 service/product with ODM at a time. However, A dealer can use 1 Co-Op brand for social media services and 1 Co-Op brand for additional ad funds* or website. The additional ad funds must still follow Co-Op guidelines set by that tire specific program.
*That being said, if a dealer is using Bridgestone at 100% for services, they may not use another brand to Co-Op their additional ad budget or website, as the requirements for 100% means that no other tire brands may be highlighted on the pages.
