Arnold, 180 Split Dunlop Tire

BOSTON — Arnold and 180, pitching separately, were the winners in Dunlop Tire’s recently completed review for $25-30 million in North American and European ad chores, the client said.

Arnold, Boston, not a roster shop, adds North American duties; 180 of Amsterdam — in an unexpected development — retains the European portion of the business, according to Dunlop.

Bartle Bogle Hegarty, pitching from its New York and London offices, was also a finalist. Marcus Thomas, Cleveland, which handled some domestic work for Dunlop, did not participate but has said it expects to continue working with the client.
