KUMHO Tires introduces tires with scents in the United States.
The first Aroma tires will have a lavender scent. Later the company introduces orange and jasmine scents. Why would somebody want a scented car tire? Maybe after you have everything else pimped on your car, why not throw on some lavender tires?
KUMHO also offers colored smoke tires (photo below) for the drifters among us - now, that I understand. Having red smoke fill the air, while you paint a big doughnut in front of your local police station is cool and stylish. KUMHO introduced the colored smoke tires already in 2005. More details here.
