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?

Be curious about the results myself. I too have noticed tire noise is the most significant interior noise. Not excessive, but dropping a few dB would be of value.

I'd be interested in the results myself. I've not noticed it around town though, just on the highway. I've noticed it gets louder on concrete vs. asphalt. I noticed it when the pavement changes from asphalt to concrete the noise increases when you going the same speed.

Also I've noticed that the noise is less when the trunk is filled with luggage. Notice this when we go on trips so it makes me think you hear the rear tires more.

More road noise is definitely coming from the rear. These tires are not that noisy, but yes, you can probably get quieter ones, especially if you don't go for the economy ones. Soundproofing is better, but difficult. Some owners report just having the pullout cargo cover deployed helps. Some find a cargo mat helps.

Yes, new asphalt can be very quiet, but once it's aged for a few years it's much closer to concrete. And of course it depends on the way they surfaced the concrete when it was poured.

I have both the cargo mat and cover, which I keep deployed at all times. The biggest thing is that New Mexico has crappy roads. Even on a smooth road at 40, my lowest observed is 68.1 dBz.

Maybe it's just me, but my Niro is by FAR the quietest car I've ever had. Cabin noise is pretty low on my list of complaints. I couldn't imagine being bothered by it so much that it justifies a new set of tires, but to each their own.

Come drive in New Mexico, and you'll see what I'm talking about.it wasn't as bad when I was driving through Portland on a road trip last year, but it's definitely really bad on all of the lovely, beautiful roads we have here in Albuquerque.

I changed away from the Michelin Energy Saver tires on my Fusion and lost 2 mpg immediately.

Noisy or not, they are the best eco tires available.

My husband has a Ford Fusion Energi and complains that my Niro PHEV is louder. It probably is, but I find it more comfortable and he can barely fit one carry on suitcase in his trunk.

I accept the little bit of extra road noise from my PHEV's tires, especially when driving in EV mode when it's more noticeable. It's my PHEV's way of reminding me I'm saving money.

The tire I'm comparing them to has very similar rolling resistance scores in consumer reports testing, but I am willing to accept a bit of reduced range, since I drive 100% of my city miles on EV. On the better roads I don't mind, but there are a lot of cruddy roads in NM, plus I'm looking for a better tire compound. My Michelin Energy Saver A/S that came stock are showing dry rot already and perhaps they won't be safe to drive on after this summer sadly. I showed the progression of the cracks in between the lugs on the tread face to a couple of my techs at work and they agree that I need to do something by winter. I like the mileage, wet and dry grip, and noise level on smooth roads, but not the noise level on poorly paved or dirt roads, dry rot, snow, or ice traction.

on the spanish niro forum one user swaped for Goodyear Eagle f1 asymetric and he is very happy with the reduction of noise and comfort improvement...

In my opinion, the michelin pilot sport 4 we have over here on the 18" wheels is a high perfs sporty tire that in my opinion has nothing to do on a low power hybrid car (overkill) that is made for relax/soft driving.

Have you seen a Michelin green tire that is not on a rim or alloy wheel ? .. it's so smooth and floppy like folding a rubber mat.. not hard like the normal tires.

Next thing we are going to see here is a whole load of posts about how some oil change, or new air freshener install has ruined the MPG of their Niro. And after a whole lot of back and forth about it, it will come to light that they changed their tires and now are getting far worse fuel economy. I know that in a few years I will be changing mine and I also know that my fuel consumption will be directly effected. I am planning as I live up north to go towards a Nokian WR4 all weather tire as half of my year here is winter and I can't be bothered to change tires twice a year.

well yes and a lot of reports will be based on ...nothing :( as between the good and the bad tire (in UE they are classified between A and G) there is about 0.6l/100km diference of consuption, difference largely smaler than the difference of consuption between cold/average/hot weather with use of AC or heating, the simple fact that you drive a little smaller or little faster can make more diference than that, the tire inflation, density of circulation, ...
All these elements combined makes the 0.5l/100 diference due to tires very hard to notice unless you believe any diference is due to tires and then under worst conditions some people will say that because of their tires they consume 40% more :)

For me, a person that want a X Tire brand name on their car is a personnal choice. like a gas brand, oil brand, the consumer needs to get all the facts before buying it. If the person changes a thin that can affect either their MPG or the vehicule itself, in my book, you're stuck with it and like say's @Roadkill401 , dont come and complain after.!!

I like the original Michelin "X Green" tires that come's with the car. They are great for the summer, and for our north winters, a good snow and ice tire's from december to march.


I have no choice, the law here tells me to change them twice a year! :(

I am including a link to an article on the future of tires and a solution to tire noise.
The 1st part of the article is about a potential new tire/ wheel from Michelin called a Tweel with a neat video.
The 2nd part of the article talks about a new tire that is actually available from Bridgestone now that eliminates road noise.

I though you might enjoy reading and watching the information in the article
