My mechanic told me the same thing. I've got two bent rims now. Hard to avoid with crappy Michigan roads. I'm going to switch to my winter tires (& rims) and then worry about getting the other rims replaced in the spring.

High pitched tire noise @ highway speeds by nissmazlover

Anyone experience an inordinate amount of high-pitched tire noise highway speeds? I noticed this after I got my tires rotated and balanced. It is REALLY annoying! What do u think it might be?

It could be your tires are "cupped" and depending on how they rotated the tires, they may be going the opposite direction and creating this hitch pitch sound.

What does that mean that they might be "cupped"? I knew it had to do something with the tire rotation and balancing I got since it never made that noise before. Please advise. Thanks!

Tires normally wear evenly, meaning that the entire tread wears down in an even manner. When your vehicle is out of alignment and/or not balanced correctly and/or have bad shocks the tire tread wears uneven and the design on the tread literally wears in a "cup" or "bowl" (for lack of a better term) like manner, sort of like one or both edges of the tread pattern are higher then the center portion. Sometimes it goes unoticed because the tire remains in the same position and the tire gets accustomed to the rotation on that particular corner. However, if that tire gets moved to a new location, as in a tire rotation, it will make a humming noise, kind of like big off-road tires on a truck, because it is rotating the opposite way (if the tire is NOT directional) or just plainly trying to get accustomed to the new corner that it is in duty of. The noise you hear is the higher portion of the patterns on the tread that will eventually wear down first, however this can take time and the noise can sometimes increase rather then improve.

WOW! Thanks for that very descriptive explanation. You sound like an auto technician.
 
Anyway, I didn't notice the noise until AFTER the tire rotation and balancing. The shocks and suspension are totally fine - the car's only a year old. But, before the balancing, I noticed a slight tremor over 60 mph, which indicated that one of my wheel weights had fallen, right? Well, after the balancing and rotation, the tremor is completely gone and the car is completely smooth again, BUT I hear that high pitched noise at highway speeds on CERTAIN very SMOOTH roads, especially when raining. And the sound sounds a lot like what you described, only at a higher decibel most likely because the tires are smaller than big off road tires.
 
I certainly hope the tire(s) get(s) accustomed to the rotation and that the noise goes away. I've noticed that ever since I returned to NY from NC the noise has somewhat dissipated, but on certain smooth highways, I still hear it, albeit less than when I first noticed it in NC. So, maybe it is going away. In any case, it's an annoying noise and it makes the car seem cheap. My wife was complaining about it and she hated the noise and said it made the car seem like an $8K Kia, or something. I do hope it dissipates.
 
Thanks for your explanation, though! Is there anyway to fix it?

No problem there nissmazlover, I am not a technician but I have been in the auto dealer parts business for 9 years now and it doesn't help that I am a car nut.
 
It sounds like your tires might have already started their "re-accustomed" trial since you mention that it has gotten better. There really is no fix for this, other then just letting the tires wear evenly with time. However, you can prevent this from happening in the future by getting your tires rotated at least every 5K miles (or every oil change if you do your oil changes every 5K miles) and getting an alignment once a year or 15K miles just to keep those wheels and tires nice and straight. Besides, keeping your tires properly inflated, rotated and aligned prolongs the life of your tires and keeps your MPGs at normal and sometimes better levels.
 
LOL! ....watch out when you mention the "KIA" nameplate in here in a negative way, there are many RONDO lurkers that get offended...LOL!

different size tires by riproy

Someone on this board said they changed tires on their MZ5 to a 225/50R17. Do tires this size do anything to protect the OEM rims from "curb rash"? I am thinking about different sizes of tire to replace the current Toyos when the time comes.
Many people have complained about the Toyos but i haven't had any problems with mine other than they seem to be wearing rather quickly (hard to know exactly the mileage on them since we switch to winter tires every fall). Mayhe with new tires i will notice the difference.

I put 16 inch rims and 205/60R16 tires on to avoid the "curb rash" a month ago...so far so good. These tires are Good Year triple tred Assurance. Apparently they have a thicker side wall and longer tred wear. They feel much more substantial and look great. I can post a picture of them if anyone is interested.
 
Regarding road noise. In general, I do not think this car holds out road noise as I could hear both my old and new tires. It is not a big deal to me but I have seen this post in a few forums. It WAS a big deal when my tires and bent rims were making noise...drove me nuts...hence the reason I went with new rims and tires.

Yup, that was me, Michelin MXM4 Pilot HX 225/50R17 93V
 
Considering that the sidewall is 0.4 inches taller then stock tire, I would assume that it gives a little bit more protection against bending rims, and the fact that it is almost an inch wider as well, I am sure that curb rash is less likely then stock tires.
 
See for yourself here.
