    We have 2 Claritys, same age and trim so they're practically identical except for colour and we swapped wheels on one of them. One car is running stock wheels & tires - Michelin Energy Saver A/S and the other has aftermarket 18" RTX aluminum wheels on the same stock tires. Driving the two, I thought I was hearing a slightly higher noise level at times on the aftermarkets but wasn't sure if it was just in my head after reading about the noise reducing resonators in the Clarity wheels. Naturally, I took my son out for two identical drives in each car to help me measure the road noise with a sound level meter and sampled the same 8 roads. Speed ranged from 10km over our driveway curb, 40 km on subdivision residential roads, 60 km on city streets and 70 km on a bigger city street. I thought this was enough to detect a difference and it was. On average, the Honda Clarity stock wheels with the integrated noise reducing resonators were 1.2 dB(C) lower. Way to go Honda!

    Thanks for the data. Good info. I assume the tires have the same number of miles on them?

    what about wheel alignment? the stock tires that came with the car may have an unfair advantage. just saying

    Changing tires and/or wheels doesn't change the alignment of the suspension.
