The CSL has severe image problems and the capture of a big international brand with links to football is a major boost to the 16-team league, which starts its sixth season on Saturday.
"To revive the depressed CSL is a big a challenge but that's our plan and hope over the next few years," Nan Yong, the deputy chairman of the Chinese Football Association (CFA), told a news conference.
"During a period when many companies are cutting sponsorship in sports marketing, Pirelli are signing a three-year contract with the CSL. This shows their long-term vision."
"Pirelli's experience in promoting football will definitely help us close the gap between the CSL and top international leagues," added Nan. Chinese soccer has become associated with violence, protests, crime and allegations of corruption over the last few years and has struggled to attract sponsors.
The CSL's first sponsor, Siemens, departed abruptly after one scandal-ridden season and there was no replacement for 2005.
"The world, as we know, is suffering an economic crisis but we are very optimistic about China's situation," said Giuseppe Cattaneo, chief executive of Pirelli Tyres China.
