Installed new 32" Falken Rubitrek tires this week and thought some of you may be interested in the resulting decibel change from the original tires with ~1,000 miles on them. This is absolutely NOT a scientific study, just my wife down writing the numbers while I was driving and holding my cell phone with a decimal meter app. We tried to duplicate how we took the readings from the original tires to the new ones as close as we could but if you've ever tried this it is challenging. We did take the same route while we were doing this so any pavement difference wouldn't affect the readings. Radio and fan both off. 20 psi in both the original and new tires. Comfort mode and single rear wheel drive.
When i left the dealership with the new tires I was immediately impressed with the sound difference. After we took the decibel readings I thought well maybe it wasn't as much difference as I thought. However when I read about decimal differences I believe perceptible sound actually doubles with every 3 decibels. So it appears once we got above 25 mph the sound is actually about half what it was from the original tires.
To me the original tires had a real roar to them and with these I can barely hear them. Other sounds like seat belt rattles, transmission sound, wind etc. become more apparent though which I expected.
