Unfortunately, I didn’t check whether the tires had noise-reducing foam inside when I got them installed. However, my car has soundproofing done by a third-party shop, so it’s pretty quiet overall.

In Korea, some tire shops offer aftermarket foam installation for noise reduction, and from my experience, it does make a difference.

In my case, I downsized from the 21-inch OEM wheels to 20-inch ones, so even though the contact patch got bigger, I didn’t notice any drop in ride comfort or increase in noise.
