If road noise is what you are trying to quell the first place to look is tires.

After that I would suggest getting a quote to have Dynamat or a similar sound absorbing material installed in the interior of your vehicle.

Regarding tires, this is just our one instance, but tires made a huge difference in road noise with our 2014 Toyota Venza, known for being loud inside. We bought summer tires for it and went for the ones with high life expectancy. The hard compound supposedly gives back longer life but they're noisy due in part to their hard compound. Our winter tires are much softer with an aggressive tread pattern.

Turns out, even with the aggressive tread pattern, the winter tires aren’t nearly as loud as the summer ones, just the opposite of what we expected.


So, yeah, from my limited experience tire selection could be a big deal. But then how do you arrange an A/B comparison? I don’t know how you could arrange for that.
