Auto parts and repair outlet chain Pep Boys ( PBY) reported a $9.2 million loss for the first quarter because of a charge. Before the item, profit still fell 33% because of weaker tire sales.

According to general accounting principles, the company lost 18 cents a share for the quarter ended May 3. This compares with last year's earnings of 26 cents a share.

Excluding one-time items, the company earned $9.1 million, or 17 cents a share, compared with $13.6 million, or 26 cents a share, in the prior-year quarter. Analysts were expecting the company to earn 21 cents a share.

"Industrywide weakness in the replacement tire market, coupled with low consumer confidence which continues to depress discretionary spending, negatively impacted our tire, service repair and accessory merchandise businesses," said George Babich, Pep Boys' president.

Total revenue was $529.2 million, down 5%. Same-store sales also fell 5%, the company said.

Shares of the Philadelphia-based company closed at $9.71 Wednesday.
