Quieting road noise

So I have to say my Mom had a 2005 Equinox when they first came out, and it was a really nice vehicle with the exception of the road noise. My 2014 is not any better. I've noticed that the Silverado and some of the other GM models have 'carpet' in the wheel wells to quiet the road noise. I would like to add some to my Equinox, or some type of Dynamatt product. Any suggestions?

I like the the "" carpet "" idea in my 2016 Sierra , and it doesnt hold debris. Very quite.

Noxs have alot of road noise , changing from the OEM Michelin Lattitude tires would make a huge difference.

Only thing i would try in the wheel house is GM Rubberizied Undercoating .... would it adhere to scuffed up ( Scotchbrite )
liners ?

yeap, look for tires that are rated highly for low road noise.


Our Nox, got quieter when I went from the factory tires to some Toyo Versados.


That should give you a start.

My experience has always been that all new tires are quiet (enough) initially - probably because the rubber is so fresh and pliable (and tread pattern factors into this, too). But then, as the tires age, they *can* become louder - maybe depending on how they wear, or how less pliable the rubber becomes over time?

Don't forget, too, that there are different road surfaces out there, and some of them contribute a LOT to road noise. Who hasn't been rolling down the Interstate on a long drive with a quiet cabin and heard road noise that made you think you had a tire problem on your hands? But then the road surface changes and the noise goes away...

agreed.
Yes, quiter when new...


Though, if I believe what I read, some features put into the tire tread design can make them a little quieter.
If youre looking at say 2 tires made by the same manufacturer.... they will have ratings on traction, noise, etc.
I would choose the one that has the better rating for being quiet. (assuming the other specs are close or equal).






our 2007 Impala. 3.9L V6 with factory dual exhaust

When I replaced the tires, on the way home on the highway, I kept hearing what I thought was a vehicle/truck next to me in my blind spot, and I kept turning my head to look for the vehicle in the next lane. None.



Well it turns out, that what I was hearing was MY Impalas dual exhaust...............

The new tires where quieter. I heard my duals sound for the 1st time.



Even when the car was new and had the new factory tires, I had never heard the dual exhaust on the highway (windows up), like I did that day with the new tires.

But aren’t those tire ratings subjective (assigned by the manufacturer)? I know I’ve read that the treadwear or treadlife numbers are. The manufacturers assign their own numbers and you really can’t compare them from manufacturer to manufacturer because there’s no standardization.

I think the only numbers you can trust on a tire are the size and manufacture date.

Is there any info/general guidelines out there about tread design and what to look for to buy the quieter tires?

Dynamat. Look it up. Take out some of your interior panels in the back, (easy to do), lay down some dynamat, and button it back up. It will be a tremendous improvement.

Yeah, but it's still their own rating system. So "our tire A is quieter than our tire B", but how quiet is it *really*?

It's relative quietness (within one brand) when what you really might be looking for is absolute quietness (across all brands).

That's why I said knowing what to look for in the actual tread design might be the best way to pick the quietest tire ... but it's probably not that simple.

And then factor in the road surface contributing to the noise - and maybe even how different tires amplify the noise differently from different road surfaces.

Probably need a TNC system (Tire Noise Cancellation) in your vehicle, tuned for your installed tires, to really get it right.

Isnít road noise subjective? I remember one poster when I had the 2012 Equinox that complained the cabin noise in his was loud whereas we never felt ours was noisy.
