Based on my knowledge, products sold on Amazon may involve infringement issues, including tire covers. As for how to determine whether a tire cover infringes, you must first consider the following aspects:

1. Trademark rights: If the tire cover uses someone else’s registered trademark and does not obtain authorization from the trademark owner, it may constitutes trademark infringement.

2. Copyright: If the design, pattern or text on the tire cover enjoys copyright protection without the permission of the copyright owner, it may involve copyright infringement.

3. Appearance patent rights: If the shape, shape or other appearance features of the tire cover are patented by others, selling similar products without authorization may constitute appearance patent infringement.

4. Market infringement: Selling tire covers on Amazon may be considered false advertising or infringement if there are product quality issues.

It should be noted that the determination of infringement issues requires comprehensive consideration of applicable legal provisions such as relevant trademark law, copyright law, patent law, and relevant judicial interpretations and precedents.

If you believe that someone’s tire covers sold on Amazon infringe upon your legal rights, you can file a complaint through Amazon’s intellectual property protection procedures, or consult a legal professional for more detailed guidance.
