No, a car dealer generally cannot legally sell a car with bald tires to a consumer. In the United States, selling a vehicle with tires that have a tread depth below the legal minimum is a violation of state safety inspection laws and can be considered an unfair or deceptive practice under consumer protection laws. The legal tread depth minimum in most states is 2/32 of an inch. Tires worn beyond this point are considered bald and are dangerously unsafe, significantly increasing the risk of hydroplaning, blowouts, and loss of control, especially in wet conditions.
The primary regulation governing this is the Federal Trade Commission's (FTC) Used Car Rule. This rule requires dealers to post a Buyer's Guide in the window of each used car. This guide must clearly indicate whether the vehicle is being sold "as is" or with a warranty. However, even an "as is" sale does not absolve the dealer from selling a car that fails to meet basic state safety standards. A vehicle with bald tires is inherently unroadworthy.
If you unknowingly purchase a car with illegal tires, you have recourse. You should immediately contact the dealer to request they rectify the situation. If they refuse, your next steps are to file a complaint with your state's Attorney General's office, the local Department of Motor Vehicles (DMV), or the FTC. The dealer could be forced to replace the tires and may face fines.
From a purely practical standpoint, any reputable dealer will replace bald tires before sale. It's a significant red flag if a dealer is willing to sell an unsafe vehicle. Before finalizing any purchase, always conduct a personal inspection of the tires. Use a quarter for a quick tread depth check: insert it upside down into the tread groove. If you can see the top of George Washington's head, the tread is too low.
