My front tires on my 2006 hyundai sonata keep wearing out on the inside. I have replaced the tires and had them aligned at the dealership and had the car checked for other problems. They have told me there are no problems and that the car was not that bad out of alignment for the tires to wear that bad. I have two cars just alike is this a common problem with these cars or am I doing something wrong?

SOURCE: Tire wear

does the car make noise from the rear when you go at a high speed. If it does it may be your bearings. I had my bearing wear out on me at 15000 miles.

SOURCE: I have front end vibration

just checked this out a while ago:



Wheel Hub Assemblies: Systems and Diagnosis of Worn Hub Assemblies & Bearings
Front wheel hub assemblies and bearings control the position of, and reduce the resistance of, vehicle wheels in contact with the pavement. When they fail, front wheels may not be kept in position and vibration and noise usually develop. Symptoms that normally develop as a result of these worn parts include:

• A humming, rumbling or growling noise which increases with acceleration or as the vehicles turns
• Vibration felt in the steering wheel, which changes with vehicle speed or as the vehicle turns
• Looseness or excessive play in the steering wheel (especially while driving over rough road surfaces)
• A loud, constant grinding noise when driving the vehicle (heard in the most severe cases of a wheel bearing failure)
• Pulling to one side when braking.
• Roughness - with the vehicle of the ground, roughness or vibration when rotating the wheel
• Looseness - with the vehicle off the ground, looseness when wiggling the wheel back and forth (Looseness may also indicate a worn ball joint)
• Excessive brake pedal play can also indicate sloppy or excessively loose wheel bearings
• ABS failure in the system may be related to failure of the ABS sensor in the hub assembly or the internal sensor in the wheel bearing

there may be a rear alignment issue but I'd check with a garage that can check your tracking

1. It's hard to say without looking at the vehicle (and test driving it) but more than likely the front end is badly out of alignment. ( If the car has been in a significant front end accident and badly repaired then this could also be a source of the problem as the alignment may not be capable of being properly set).

2. The first thing to do is take the car to a specialist suspension and steering shop and have the wheel alignment checked and adjusted to factory specs. Normally this is not expensive for a straight forward alignment but price depends on the shop. A good suspension shop will also identify if there are any wear problems with the steering or suspension that need attention

3. Older drivers sometimes frequently hit kerbs when parking their cars. This will throw out the front wheel alignment every time (and damage tyres) so it must always be avoided. Scrubbed.scuffed tyre side walls are an indication of this as well as scratched wheel rim edges.

4. Some drivers never check tyre pressures. Low tyre pressures will cause much greater tyre wear as there is more friction. (It will also make steering heavier, place undue stress on the steering components, cause the car to handle badly and result in much higher fuel consumption).
The lady needs to ensure her car has at least 32 lbs pressure in both front tyres and at least 30lbs in the rear (which carries less weight). The pressures must be set with COLD tyres. Manufacturer optimum spec tyre pressures are usually set for comfort. These can be safely exceeded by a few pounds. It is far safer (and more economical) to run slightly higher pressures than a setting that is too low. (A good tyre will run all day with 38-40 pounds pressure and 36-38 is quite safe).

5. Worn out shock absorbers will also contribute to abnormal tyre wear. 70000 miles of average driving will see out a set of shocks. (Personally I would not leave them that long as the factory shocks are generally of average quality on this type of car)..

That's the best I can do Brad without seeing the car so I hope this helps some. Hopefully a good wheel alignment will fix the problem but make sure the tyre pressures are kept up as well. If the shocks are worn out they will also need to be replaced if the car is to be roadworthy.

SOURCE: Tire wear in middle of both rear tires

problem is with over inflating the tires,causing middle tread wear,as long as you have more the 3/32 tread wear in the middle than you are ok.always set tire pressure when cold at around 33psi,check tire inflation sticker on dar jam for exact tire pressure
