Report of Independent Registered Public Accounting Firm

Pre-Tax Savings Plan Committee
Cooper Tire & Rubber Company
  Pre-Tax Savings Plan (Clarksdale)

We have audited the accompanying statements of assets available for benefits of the Cooper Tire & Rubber Company Pre-Tax Savings Plan (Clarksdale) as of December 31, 2003 and 2002, and the related statement of changes in assets available for benefits for the year ended December 31, 2003. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Accounting Company Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the assets available for benefits of the Plan at December 31, 2003 and 2002, and the changes in its assets available for benefits for the year ended December 31, 2003, in conformity with U.S. generally accepted accounting principles.

Our audits were performed for the purpose of forming an opinion on the financial statements taken as a whole. The accompanying supplemental schedule of assets (held at end of year) as of December 31, 2003 is presented for the purpose of additional analysis and is not a required part of the financial statements but is supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental schedule is the responsibility of the Plan’s management. The supplemental schedule has been subjected to the auditing procedures applied in our audits of the financial statements and, in our opinion, is fairly stated in all material respects in relation to the financial statements taken as a whole.

1. Description of Plan

The following description of Cooper Tire & Rubber Company Pre-Tax Savings Plan (Clarksdale) (the Plan) provides only general information. Participants should refer to the Plan agreement for a more complete description of the Plan’s provisions.

General

The Plan, as amended and restated effective January 1, 2001, is a defined contribution plan covering all hourly employees who have completed 30 days of continuous credited service and are covered by the collective bargaining agreement between the United Steelworkers of America Local #556 and Cooper Tire & Rubber Company (the Company and Plan Administrator). The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA).

Contributions

Each year, participants may contribute up to 15% of their pretax compensation. Participants may direct their contributions to any of the Plan’s investment fund options.

The Company contributions are made annually as provided in the Plan document and at the discretion of the Company’s Board of Directors. All Company contributions are invested in Cooper Tire & Rubber Company common stock until they become vested, after which they are invested as directed by the participant.

Participant Accounts

Individual accounts are maintained for each participant in the Plan. Each participant’s account is credited with the participant’s contributions, allocation of the Company’s contributions, and Plan earnings. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s account.

Forfeitures

At December 31, 2003 forfeited nonvested accounts totaled $1,454. These accounts will be used to reduce future employer contributions. In 2003, no forfeited nonvested accounts were used to reduce employer contributions.

1. Description of Plan (continued)

Vesting

The participants are immediately vested in their contributions plus actual earnings thereon. After five years, the participants are 100% vested in the Company’s contributions plus actual earnings thereon.

Participant Withdrawals

In the event of retirement, death, termination, permanent disability or other separation from service, participants are entitled to receive an amount equal to the value of the vested interest in their accounts. Payment of benefits may be taken in a lump sum distribution or in two lump sum installments.

In the event of hardship, as defined, participants may make a partial or full distribution of their accounts, subject to certain tax withholdings.

Termination of the Plan

Although it has not expressed any intent to do so, the Company has the right under the Plan, to discontinue its contribution at any time, to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants will be 100% vested in their accounts.

2. Summary of Accounting Policies

Basis of Accounting

The accompanying financial statements are prepared on the accrual basis of accounting. Participant withdrawals are recorded upon distribution.

Investment Valuation and Income Recognition

Except for the investment contracts held in the Investment Trust, the Plan’s investments are stated at fair value, which equals the quoted market price on the last business day of the plan year. The shares of mutual funds are valued at quoted market prices, which represent the net asset values of shares held by the Plan at year-end.

2. Summary of Accounting Policies (continued)

Investment contracts are recorded at their contract values, which represent contributions and reinvested income, less any withdrawals plus accrued interest, because these investments have fully benefit-responsive features. There are no reserves against contract values for credit risk of contract issues or otherwise. The average yield was approximately 4.2% in 2003. The crediting interest rate for these investment contracts is reset monthly by the issuer but cannot be less than zero and ranged from 1.4% to 6.6% at December 31, 2003.

Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date.

Administrative Expenses

The Company pays the administrative expenses of the Plan.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles require management to make estimates that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

3. Investments

During 2003, the Plan’s investments (including investments purchased, sold as well as held during the year) appreciated in fair value, as determined by quoted market prices, as follows:

Investments that represent 5% or more of fair value or Plan’s assets available for benefits are as follows:

4. Investment Trust

Certain investments of the Plan are held in an Investment Trust, which also combines similar investments of the other defined contribution plans sponsored by the Company. Each participating retirement plan has an undivided interest in the Investment Trust. The Plan’s interest in the Investment Trust was determined by the Plan’s relative asset value to the Investment Trust’s total asset value at the end of the year. Investment income is allocated to the Plan based on its pro-rata share in the net assets of the Investment Trust.

At December 31, 2003 and 2002, the Plan’s interest in the net assets of the Investment Trust was approximately 0.05% and 0.06%, respectively.

5. Nonparticipant-Directed Investments

Cooper Tire & Rubber Company common stock and in the Investment Trust is a nonparticipant-directed investment. Information about the significant components of changes in net assets related to the nonparticipant-directed investment for the year ended December 31, 2003 is as follows:

6. Income Tax Status

The Plan has received a determination letter from the Internal Revenue Service dated July 2, 2003, stating that the Plan is qualified under Section 401(a) of the Internal Revenue Code (the Code) and, therefore, the related trust is exempt from taxation. Subsequent to this issuance of the determination letter, the Plan was amended. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. The Plan administrator believes the Plan is being operated in compliance with the applicable requirements of the Code and, therefore, believes that the Plan, as amended, is qualified and the related trust is tax exempt.

7. Related Party Transactions

Certain Plan investments are shares of mutual funds managed by the trustee, National City Bank, and, therefore, these transactions qualify as party-in-interest transactions. There have been no known prohibited transactions with a party-in-interest.

8. Risks and Uncertainties

The Plan invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market and credit. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that the changes in the values of investment securities will occur in the near term and that such changes could materially affect participants’ account balances and the amounts reported in the statements of assets available or benefits.
