The Schedule 13D (the "Schedule 13D") filed on October 24, 2005 by JANA Partners
LLC, a Delaware limited liability company (the "Reporting Person"), relating to
the shares ("Shares") of common stock, no par value, of Titan International (the
"Issuer"), as amended by Amendment No. 1 and Amendment No. 2 to the Schedule
13D, is hereby amended as set forth below by this Amendment No. 3 to the
Schedule 13D. The principal executive office of the Issuer is located at 2701
Spruce Street, Quincy, Illinois 62301.

By oversight the Reporting Person failed to amend this Schedule 13D following
its purchases on May 25, 2006. Such purchases however were timely reported in
its publicly-filed Statements of Changes in Beneficial Ownership on Form 4.


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

       Item 3 of the Schedule 13D is hereby amended and restated as follows:

       The 4,498,800 Shares reported herein by the Reporting Person, were
acquired at an aggregate purchase price of approximately $74,404,376. The Shares
beneficially owned by the Reporting Person were acquired with investment funds
in accounts under management.

Item 5.     Interest in Securities of the Company.

        Paragraphs (a), (b) and (c) of Item 5 of the Schedule 13D are hereby
amended and restated as follows:

        (a) The aggregate percentage of Shares reported to be beneficially owned
by the Reporting Person is based upon 19,731,332 Shares outstanding, which is
the total number of Shares outstanding as of July 26, 2006 as reported in the
Issuer's Quarterly Report on Form 10-Q filed on July 28, 2006.

       As of the close of business on September 21, 2006, the Reporting Person
may be deemed to beneficially own 4,498,800 Shares constituting approximately
22.8% of the Shares outstanding.

        (b) The Reporting Person has sole voting and dispositive powers over the
4,498,800 Shares, which powers are exercised by the Principals.

        (c) The following transactions in the Shares were effected by the
Reporting Person since the filing of Amendment No. 2 to the Schedule 13D. All of
the transactions in Shares listed hereto were effected in open market purchases
on the NYSE market through various brokerage entities.
