1. Observe the logo on the tire: The logo of the double-star tire is usually clear and vivid, and the font and pattern are standardized. If the logo is ambiguous, or the font and pattern are not standardized, it is likely to be a counterfeit product.

2. Check the quality of tires: The quality of real double-star tires is usually better, the rubber of tires is soft and elastic, and the patterns and lines of tires are clear. If the tire quality is not good, or the patterns and lines are blurred, it is likely to be a counterfeit product.

3. Check tire prices: Double star tire prices are usually relatively stable. If the price is too low, it is likely to be a counterfeit product. In addition, if the purchased tires do not provide formal invoices and warranty documents, then you need to be vigilant.

4. Choose formal sales channels: When buying double-star tires, it is best to choose formal sales channels, such as officially authorized dealers or large auto parts stores. This can avoid buying counterfeit products.
