Prius (2010-12) :: How Did All 4 Tires Get Cupped On Inside - Road Noise Is Much Higher
May 27, 2011
Four months after I bought my Prius III last year, we discovered that the left rear wheel was so out of alignment that it ruined the tire in 5,000 miles, and then also ruined the one put in its place during regular tire rotation. Toyota replaced the entire set of tires, and I checked the alignment this fall and again this spring when I took off the snow tires.
Everything looked fine. Nevertheless, when I rotated the tires today, the tech reported that ALL FOUR tires were substantially cupped on the inside, after only 6,000 miles on this set of tires. Road noise has become much higher. It doesn't make sense that all four wheels got similarly out of alignment in just two months.

I noticed when driving on a rough surface/road (gravel, snowy road with sand) the there is a considerable amount of noise coming inside the cabin on the rear end especially.
When I was doing a quick wash today I just realized the sound is coming from the wheel base. On the rear and front end there is a plastic covering the wheel base. Sound proofing / undercoating wheel base.

I am looking to reduce some road noise from the Tiguan and will probably install some Dynamat. Mostly I am looking to soften road noise coming from the tires. Any recommendations on what type and where the most beneficial spots to dynamat would be? There seems to be a lot of choices to choose from and every car seems to have it's weak spot as far as noise goes. Wheel wells and firewall, perhaps?

Feel there is excessive road noise on the highway? (not wind noise)
Seems as though it can be worse depending on the surface. Comparing the B7 to the wife's Q5 is painful. Heck, even my MKVI GTI was silent compared to this. What do you all is a good fix?
Tires? If so, what would be a good upgrade? The P Zero Neros on the GTI seemed pretty good. I'm new to car tires. Long time Jeeper. Dynamite under all carpet?

I have a VW Jetta Sportwagen with 17" wheels and Conti 225/45R17H low profile tires. Ever since I first bought the car, i have been annoyed by the higher-than-expected road noise. Perhaps this is caused by the tires, perhaps by the body characteristics of a wagon, perhaps it's just the noise anyone would get from a Jetta chassis. The tires are due for replacement soon, and I'm wondering if I would experience a meaningful reduction in road noise if I switched to 16" wheels and less sporty tires? It wouldn't be cheap to replace wheels and tires, but it could be worth it if the noise level drops significantly. If the wheel change is not worthwhile, which 17" tires would be a quieter choice?

I have a 2007 Nissan Quest with only 74,000 miles. We recently bought new tires for it (like about year ago, and not very expensive either) and in the past few weeks it has developed road noise. I know sometimes tires wear differently and generate noise but this is more of a "whirring" sound. Could it be bearing? Torque converter? Axles?

It's only at higher speeds ( read highway travel ) that I have an issue with the road noise intruding into the cabin....mostly emanating from the rear, as best I can tell. I can live with it but I prefer not to.
I took my car to a buddy who operates a shop dealing with high-end stereo conversions, etc. Surprisingly, he said he deals with these issues all the time....including vehicles in all price ranges. He uses a product that he claims to be very effective at deadening the transfer of road noises. I had him look over my SF and make recommendations.
The product comes in fairly large sheets that are easily trimmed to conform to the spaces being treated. These sheets appear to be some sort of rubber based material. The product is applied to the inner surfaces of the car's exterior metal. Once applied ( primarily a gluing-on process ) the stuff adheres there, according to him, " for life ".
For application, he has to remove all the interior plastic pieces so he can get to the exposed body metal behind them. In my case, he would also do the rear doors so the interior door panels on those doors will also come off. Once he has access to all the areas he wants to get at, he preps the metal and glues on the product. According to him, getting all the plastic parts and door panels off, and then back on, is a snap.

Slow speeds. I am noticing a roaring noise. Almost like a big truck with oversize tires. It doesn't seem to change turning left or right. I rolled each wheel and didnt get any play. Rotors and pads in great shape. I did notice when one wheel is jacked up and I turn it (clockwise/CCW) it seems like there is a lot of play...maybe in the tranny or just the axle.

We have had our 2010 with 20k miles for about 3 weeks now. I can honestly say that I can't remember being more disappointed in car. Specifically, the road and wind noise above 60 miles an hour can at times be unbearable. The Prius makes the inside of my 14 year old BMW sound like a Lexus.
I thought it might be the tires since the originals were worn. We had an unrepairable leak in one tire so we went ahead and put brand new Michelins on the car. There was only a minor improvement in noise.

My tires are cupping on my Azera. I've had the tires rotated every 7500 miles as required by the maintenance schedule. The tires make a lot of noise while driving, especially at highway speeds.

My 2012 RX350 now for over a year and like it a lot.........BUT.
There's seems to be a lot "road noise" that's transmitted back into the cabin, like driving over expansion joints on blacktop or rough road surface, is this normal?
I drove a 2000 RX300 for 100,000 miles and don't remember it being this noisy. Interior noise is great and quiet.

So my several month old Prius II has developed a metal on metal sound when I'm hitting various road bumps.. it's a "clack" sound emanating from my wheel well area that is heard when the windows are down.. I've taken it in twice and the first time they couldn't figure it out... second time they said they drove mine and a brand new Prius which also has the same sound and said it was the brake calipers. Funny thing is, I never heard this noise until after about 2k miles on my car.. They also would NOT disable my reverse beep sound or seat belt beep saying it was a safety feature and shouldn't be disabled.

I've owned a 2012 Prius Two for less than a month now, and today while driving home I noticed what sounds like road/wind noise coming from the rear passenger side area. Googling about this revealed information about the battery fan. However, I'm unsure if what I'm hearing is the battery fan or road/wind noise that I just haven't heard before.
Here's information regarding the conditions I was driving in:
- 84 degrees outside temperature
- car had been sitting in an open-air parking lot for about 2 hours
- no tint, no windows cracked for hot air release
- upon returning to the car I turned on the AC to 68, set at mid range speed
- was driving on the interstate doing some stop-and-go, but mostly 50-plus MPH
- windows rolled up completely, no doors ajar
- it sounded like air rushing by
- could not hear anything coming from the left rear side, but my left ear is partially blocked by the headrest, so...
- sound would decrease in volume if car slowed down
- sound would increase in volume as car got faster, but would eventually level out it seemed
- sound would completely go away at speeds below 20ish mph
- sound would not change based on level of AC, whether on, low, high or off
- checked battery vent for obstructions/debris, saw nothing, and was cool to the touch
- car has about 28k miles on it, replaced rear tires yesterday but all bolts, caps, etc. are securely in place

I have a 2011 Prius 2, with 35K miles, and have noticed a clicking sound in the steering when hitting a small bump or hole in the road. If the car is parked, I can rock the steering wheel back and forth, and hear a clicking sound. I do not remember the noise being there until recently.
Also the radio reception seems to have gotten weaker. If I am on a trip out of town, it now seems that I am looking for stronger stations frequently, as static interferes. I had the car to the dealer for this a few months ago, and they said they could not duplicate the problem
This car is about ready to drop off the warranty, and would like to have Toyota pay for the repair if it is needed.

This system has a feature that is supposed to adjust the sound level to compensate for road noise etc. I had a Ford with this feature and you could adjust the sensitivity. It worked great; adjust the volume sitting still and the volume went up and down as you traveled.
In the 2010 Prius, I have enable the feature but I cannot figure out if the sensitivity can be adjusted and I do not hear that it is working. I set the volume and start driving and as the road noise increases the sound just gets drowned out. If you turn it up, when you slow or stop it just blasts loudly; no adjustments at all.

Is there a typical cause for whistling noise on Elantra ? Mine is a 2011. The whistling noise started recently, and occurs only at high speed say 80 kph and higher. It definitely sounds like wind noise, constant frequency no matter the speed. Does not sound like brake noise or belt noise, and does not change with changes in accelerator or brakes. I have taped up most gaps around the front of the car, including all around the windshield, with no impact. Note that I recently fixed a windshield wiper washer nozzle, which necessitated the removal of the plastic assembly that sits atop the bottom part of the windshield. The re-installation went well and everything seems well seated down (I had to replace 4 plastic rivets).

Today was the first day I drove my Elantra on the interstate with the sunroof open. When I was cruising at 65-70mph, I kept hearing a noise that I thought was coming from another car. It sort of sounded like a popping or thumping noise. After a few minutes, I reached my hand up and noticed the sound was coming from the metal bar that rises up a little at the front of the opening when the glass slides back. The wind was vibrating it and making it flap in the wind.

I knew when I bought my car it wouldn't get optimum mpg as no car would with the many short trips I have to make every day but I have 5000 miles on it already and have averaged approx 46 with all the city and highway combined.
I took it into Toyota last week for the tire rotation and ever since it has been horrible. There were 120 miles on the tank and I refilled because I couldn't stand to see it staying around 39 on the computer. I have never seen that before. I checked the tired and they had brought them down to 32psi so I put then back to 40/38 and refilled.
Not noticing much of an improvement, sadly. Hovering at 40 mpg still. Weather has changed a lot. Temps much higher daily mid 80s to low 90s. This is my first summer with the car and yea the ac has been on nonstop with the higher temps.
