Hi

I Have around 25000 KM on my 2019 Kia Sorento EX 2.4 L and it has Kumho tires. I bought this car used. Compared to all my previous cars or SUV I think this SUV has more tire / road noise specifically from the rear tires. Sometimes I check all my windows thinking I have left one open. Tread depth is still pretty good on the tires.

I was wondering is this normal in the SUV or when the time comes should replace it with diff tire which will reduce tire road noise or I should get this checked out at the dealer?

You might want to check to see if there's been an issue with alignment on the rear. Not unusual to get a lot of road noise if the camber in the rear is off since it 'feathers' the tires.
Run your hand around the outer periphery of the tread of your rear tires in BOTH directions. If you notice a raised edge at each block when you run your hand in one direction, that will be the source of major noise.

Keep your tire pressure at recommended psi.
Have the tires rotated, just back to front, no criss-cross, and see if that helps.
Have the tire balance checked (all 4), you may have lost a weight.
Follow ecanderson's advice!

My Sorento came with Hankook tires and is very quiet with no noticeable tire/road noise. I had Kumho's on my Optima and I was disappointed with how fast they wore out.

I have 33K miles on my OEM Kumho Crugens, and they emit noticeably more noise now than when new. But there is still plenty of tread left.

Hi, we tried out the EX 2.4 and found it to be very loud—both wind and road noise. Upon doing some research we learned that the v6 model has better soundproofing (floor and glass).

that is what my thought was and I think this 2.4L version is more for the rental market. BTW, which tires do you have?

Give the suggestion in Post #2 a try and let us know what you find.
I tried doing the test which you had mentioned and I am not sure about the result :) I am not an expert in this auto field hence thinking of mentioning this noise issue to my dealer during my next oil change visit.

Rub your hand around the circumference of the tire tread, along the outside edge of the tread (not the side of the tire, the tread) in both directions (clockwise and counterclockwise). If you notice lots of 'raised edges' in the tread blocks going one way, and not in the other, you have the problem we're talking about. The feel will be distinctly different in CW vs CCW direction. You don't need to be an expert. Give it a go.

Right now I have cheap winters on it. I can’t remember what it came with and they are currently I storage—they are quiet, but suck in the snow.

Update on my quest to fix the road noise/tire noise issue, specifically on the highway due to the wind noise / tire noise / road noise android auto voice commands are useless. I have to literally shout so that android auto can hear my voice properly now I am thinking of buying a megaphone ?and use it to give a voice command to android auto when I am on the highway.

Anyway, I ran my hand around the circumference of the tires and I did not feel any abnormality or bump to me it looked fine, tire pressure is correct too. Based on my extensive research (read Google search :)) I have zeroed down this issue to the tire. This Kumho Krugen could be kinda noisier???? someone I know has 2016 Sorento OEM 19" rims which have Hankook Dynapro HP2 235/55R19 tires and has around 80% thread on them. I am thinking of replacing my 17" with these 19". Another option is to go for sound deadening in the back or trunk area??

Any comments or suggestions or advice??

Just came across your post here regarding wind noise. I have a 2019 with v6 and also find tires and road noise to be very loud. I have Hankook Dynapro HPs, which you mention. Think they are good tires, but they are noisy. Will not buy again, but maybe it is lack of soundproofing too.

Were you able to improve noise?

Unfortunately not. To me, it more looks like a lack of proper soundproofing. I did enquire around here to add soundproofing specifically in the rear but the price quoted was $#%@&*^🤬so I dropped the idea 😎. I have not lost hope yet :) I have ordered this strip from amazon. I Will give this one a try and hoping that this will reduce some noise.

I have Kumho tires, and for sure they are way louder than other tires i have had in the past on other cars. It is sort of a whining noise. If they are anything like other factory tires I have had in the past, I won't have to be bothered by them for long, and will get something like Michelin for my next set of all seasons.
