    I'm afraid I've been spoiled by my 2016 Subaru Outback as it's pretty quiet compared to most cars. While I like most things about this Prius, I can't decide if it's the tires making noise at highway speeds, or lack of sound insulation, or both. Consumer Reports says the Ecopia from Bridgestone is rated well for noise. The only time I don't hear tire noise is either when I'm going slow or on the highway on a relatively new patch of smooth asphalt. I'm not going to trade in a new set of tires so will ride them out. Any thoughts?

    We have a different ECOPIA here in Australia - but they're about average. BUT - with your PRIUS, they've worked on weight saving, and hence my guess is that there is probably less sound-proofing. Plus, the tyres are ECO focused rather than grip.

    To offset it - you're probably using less than half the fuel an Outback was using.

    both. michelin energy savers will help, but insulating the wheel wells, spare tire area, fire wall, floorboards and etc. can really quiet things down.
    it's the price you pay when manufacturers are racing for an extra mpg

    To me it seems like most of the noise is from the front wheel wells more than the back area.
    Anyone know how to sound proof the front wheel wells?

    All Prius, at least Gen 2 and newer, are not known for quiet in the cabin. They've all been loud. Gen 4 is better than earlier, but still loud road noise-wise. Perhaps try some foam ear plugs if it really annoys you...
