Tire Shop Smell Research Findings

The video explores the distinctive smell of tire shops, which is not from the tires themselves. Researchers in Bangkok investigated this by swabbing rubber and identifying 39 species of organisms, 18 of which could survive on rubber nutrients. The final test involved determining which species produced the strongest odors. The conclusion was that the smell is a mixture of acids produced by bacteria breaking down their food.

What is the common misconception about the smell in tire shops?

• It is the smell of the air fresheners.

• It is the smell of the cleaning chemicals.
