I just bought a 2016 Sorento SXl with 60,000 miles on it. It seems to have a lot of road noies in the rear. I have a 2006 sorento that I bought new and it has always had a pretty quiet ride. I have a 2013 Ram and it sounds like a Cadilac compared to Kia. I don't know if the rear tires could make that much noise as the hav goos tread on them. I've also considered wheel bearings, but I don't know if they could be making noise at only 60,000 The front tires are a different brand than the back.
I have the LX version, and I think it is quiet. In my pre-purchase test drives I compared it to the Lexus RX350 in back to back test drives, and the LX Sorento was quieter.
Compared to the 2013 Acura RDX that it replaced, my SX was very quiet. That was with the factory Michelin's. On the other hand my Mustang is quieter than my RDX was.
Tire noise can very definitely sound like wheel bearing noise -- but unlike wheel bearings, side loading (turns) won't matter. Run your hand around the inside and outside edge of the tread of all of your tires and see if you detect very distinctly raised edges when running your hand clockwise vs. counterclockwise. If the camber has been out for any length of time, you'll find the outside edge of the tire has a very distinct 'direction' of raised edges at each groove as you run your hand around the outside. That can become VERY noisy.
Then go ahead and do the 'rub test' suggested. The low rumble that this can create is quite loud and very annoying when it occurs.
Once the tires get feathered in this manner, even an alignment and moving of the tires front/back never seems to even things out enough to get the noise down to a reasonable level.
I did thr rub test. All smooth. The tire have nearly new tread. It had an alignment done with 2 new tires and calipers on the front before i bought it. It has a trailer hitch on the back, maybe it was used for towing quite abit since the bad tires and brakes on the front. I guess the heavy load of towing could have put more pressure on the rear bearings making them noisey.
Could just be the tread pattern on the rear tires if they are different than the front. Move the tires to the front and see if the noise moves. As to your previous question about the quietest tires, usually the original tire. That is what the vehicle manufacturer would have done all the NVH testing and suspension tuning with.
If you have crappy roads in your area its going to be noisy regardless. There is a new section of freeway near me that is so dang smooth it makes all of my cars sound dead silent. The other 95% are just as noisy as can be. So yes, if your roads suck, it will be loud no matter what. But it may be slighly less loud depending on the car.
I had a 2016 Sorento with the Khumo tires, which seemed quite good and fairly quiet. With very low mileage and in only 3.5 years, they became very noisy, mainly in the back.
Tread was still excellent and no abnormal wear. I suspect just a hardening of the rubber compound, combined with Ontario's lousy roads, was the cause.
The new 2019 SX with Michelins is much, much quieter.
Only 60,000 miles for a factory tire? Only? Are you serious? Of course they could make a lot of nose with 60,000 miles. I have heard tires that are loud with 10,000 miles.
Most tires get louder with age. Do they have cupping? You can have plenty of tread with mild cupping and it will be very loud. A Sorento (EX and up in particular) is a pretty quiet car.
I just looked at the size and brand on the tires.
Front
Landsail LS588 SUV-245/55/19 60,000 mile tire-price range 121.00 to 134.00
Rear
Vercelli Strada 1 245/55/19 60,000 mile tire-price range 121.00 to 137.00
I see that they are the wrong size for the car. I think they shoul be 235/55/19
They must be a hard tire to be rated at 60,000 miles
The front are new the rear look close to new.
Yeah, someone went a bit ghetto there..... though it isn't a big deal. Ideally they should have gone with the factory size or 255/50/19 as that would be closer to the original diameter and still fit on the rims.
Do they have cupping or any uneven wear? Try running your hand over the inside tread blocks and feel to see if they are uniform or look front behind/in front of the car to see if you see cupping.
Would check the outside circumference for the raised edges, too. Have seen both Kia and Hyundai that needed camber kits where the direction of the error was showing up primarily on the outside.
Being that the rear tires are different than the front try rotating them first. I will bet you your noise is tire related. Our 2017 just broke 18k the other week and my only drivability complaint is that the factory tires are pure garbage. They were meh when new but they are aging very fast and getting noisy fast and they are way too hard so traction is an issue especially bad when it's wet.
I would really like to put new tires on it but that will wait till other projects are done. The noise is an issue but them being too hard really annoys me. I'll take a soft tire that wears out faster over a hard tire that lasts a long time.
