CUSIP NO. 8883M102                SCHEDULE 13D                PAGE 3 OF 9 PAGES


ITEM 1.  SECURITY AND ISSUER.

     This statement on Schedule 13D relates to the shares ("Shares") of common
stock, no par value, of Titan International, Inc. (the "Issuer"). The principal
executive office of the Issuer is located at 2701 Spruce Street, Quincy,
Illinois  62301.

ITEM 2.  IDENTITY AND BACKGROUND.

     (a) This statement is filed by JANA Partners LLC, a Delaware limited
liability company (the "Reporting Person"). The Reporting Person is a private
money management firm which holds the Shares of the Issuer in various accounts
under its management and control. The principals of the Reporting Person are
Barry Rosenstein and Gary Claar (the "Principals").

     (b) The principal business address of the Reporting Person and the
Principals is 201 Post Street, Suite 1000, San Francisco, California 94108.

     (c) The principal business of the Reporting Person and the Principals is
investing for accounts under their management.

     (d) Neither the Reporting Person nor the Principals has, during the last
five years, been convicted in a criminal proceeding (excluding traffic
violations or similar misdemeanors).

     (e) Neither the Reporting Person nor the Principals has, during the last
five years, been a party to a civil proceeding of a judicial or administrative
body of competent jurisdiction and as a result of such proceeding was or is
subject to a judgment, decree or final order enjoining future violations of, or
prohibiting or mandating activities subject to, federal or state securities laws
or finding any violation with respect to such laws.






CUSIP NO. 8883M102                SCHEDULE 13D                PAGE 4 OF 9 PAGES


      (f) The Reporting Person is a limited liability company organized in
Delaware. The Principals are citizens of the United States of America.

ITEM 3.   SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

     As of the date of this filing, the Reporting Person may be deemed the
beneficial owner of 2,866,500 Shares. The aggregate purchase price of the
2,866,500 Shares owned beneficially by the Reporting Person is $46,269,018.51. 
Such Shares were acquired with investment funds in accounts under management.

ITEM 4. PURPOSE OF TRANSACTION.

     On October 12, 2005, the Reporting Person's beneficial ownership first
exceeded 5% of the Issuer's outstanding Shares.

     The Reporting Person acquired the Shares for investment in the ordinary
course of business. The Reporting Person believes that the Shares at current
market prices are undervalued and represent an attractive investment
opportunity. On October 24, 2005, the Reporting Person sent a letter to the
Issuer stating that until certain questions were answered regarding the Issuer's
recent announcement regarding negotiations for a sale of the Issuer to a private
equity buyer at a price that the Reporting Person feels does not reflect the
Issuer's true value, the Reporting Person would oppose such transaction. A copy
of the letter is attached hereto as Exhibit A.

     Neither the Reporting Person nor the Principals has any present plan or
proposal that would relate to or result in any of the matters set forth in
subparagraphs (a) - (j) of Item 4 of Schedule 13D except as set forth herein.
The Reporting Person intends to review its investment in the Issuer on a
continuing basis. Depending on various factors including, without limitation,
the Issuer's financial position and strategic direction, price levels of the
Shares, conditions in the securities market and general economic and industry
conditions, the Reporting Person may in the future take such actions with
respect to its investment in the Issuer as it deems appropriate including,
without limitation, purchasing additional Shares or selling some or all of its
Shares, pursuing alone or with others further discussions with the Issuer, other
stockholders and third parties, seeking Board representation, and/or otherwise
changing its intention with respect to any and all matters referred to in Item
4.
