Since I got my Niro PHEV, I've found that the tire noise is the loudest thing in the car in town and on the highway. At 40 mph, the z weighted noise (measuring low frequency sounds transmitted through the tires and suspension into the vehicle) averages 71 dB. The A weighted noise at the same speed is just 55dB, so wind noise isn't really an issue at all. I'm measuring the noise levels with the "Sound Analyzer" app by Dominique Rodrigues off the google play store. I calibrated the app with the background procedure, and I've record several sound files, averaging them out.
I'm considering replacing the stock Michelin Energy Saver A/S with Continental TrueContact Tour tires. Tire Rack's noise comfort rating is an 8.02 for TrueContact which also performs well in snow, ice, and handling, which considering I'm going to move back to Colorado, are really important.
Does anybody already have these tires? Would you be willing to give me a calibrated sounds reading?
