Beware of fraudsters altering old tires by changing their production dates. Following a raid by the Consumer Protection Police and the Thai Industrial Standards Institute on four warehouses in Chonburi, authorities found old tires with falsified production dates being sold deceitfully. They seized 2,000 tires valued at 10 million baht.
On 17 Feb 2026 GMT+7, Police Colonel Piyawat Thonguthai, Superintendent of Division 3 of the Consumer Protection Police Bureau (CPPB), said that the Central Investigation Bureau (CIB) under the CPPB, together with the Thai Industrial Standards Institute (TISI), conducted raids on four targeted warehouses in Si Racha District and Nong Kham Subdistrict, Chonburi Province.
This operation followed investigations by officers of Division 3, CPPB, who tracked individuals illegally stocking used tires and modifying their production dates (week and year) on the tire sidewalls to mislead consumers into believing they were newly manufactured.
Such actions pose significant dangers to the lives and property of road users. Authorities monitored and intercepted pickup trucks transporting tires from the targeted warehouses and found signs of scraping and re-stamping of production dates. They then gathered evidence and obtained court search warrants to raid the four warehouses.
. The search uncovered 2,000 tires with altered production dates and tires lacking the Thai Industrial Standards (TIS) certification mark. Officials also found metal number plates believed to be used to falsify production dates. The total value of the seized items is approximately 10 million baht. Officials seized and impounded all evidence to hand over to investigators of Division 3, CPPB, to pursue legal action against the offenders.
Reporters noted that consumers looking to buy tires should check for the ECO sticker affixed to each tire. Tires certified with TIS must have this sticker on every tire. If a tire lacks the ECO sticker, it should be suspected as uncertified, downgraded, or deteriorated.
- Check for the ECO sticker on every tire.
- Confirm that the label, brand, size, and manufacturer on the ECO sticker match the tire.
- Ensure the production date (day, month, year) is clearly indicated.
- Look for the TIS certification mark and number, paired with a QR code that can be scanned to verify the tire’s origin.
