The DTM will switch from Dunlop to Hankook tires for the start of the 2011 season.
The South Korean-based manufacturer has completed a three-year deal with DTM promoter the ITR. That covers the coming season under the current regulations and the first years of new rules, due to commence in 2012.
DTM boss Hans Werner Aufrecht said: "We are very happy with the long-term partnership with premium tire manufacturer Hankook. During the negotiations prior to signing this contract, it already became apparent how motivated those in charge at Hankook are while dealing with the DTM project.
"The performance of the race tires also convinced everyone involved right away. Personally, I am happy that we have found another international corporate group that is willing and able to keep our high pace and our quality standards as an exclusive supplier in the years to come. Hankook has everything it takes for that."
Mercedes' Jamie Green sampled Hankook rubber in a recent test and said: "My first impressions of the new DTM tires are all positive.
"Hankook has identified the requirements for a DTM tire properly and managed to provide us with a tire with high grip level and good load capacity right away. The first tests with the new tires were great."
