Severe wear on inside tread -- camber issue?

[CLTCMB]

I've developed sever tread wear on the insides of my tires -- seems the rear is set for negative camber. Is this normal on the Genny? Can it be adjusted? I'd like to figure this out before I put new tires on the car.

rear tires on this type of rear suspension will wear to the inside to some degree. But should not be severe. My bmw and Mercedes have similar wear. Have your alignment checked at time new tires go on.

Did you check your tire pressure? Can you post pics? I assume when you say "inside" you mean middle portion of the tread?

I check tire pressure regularly and rotate every 5K miles. By "inside," I'm referring to the inside edge of the tread, not the center. And by severe, I'm getting to the inner layer of rubber. Obviously, I'm in the market for tires VERY soon!

I've had BMW's, as well, and have experienced this to a much lesser degree. Doesn't seem alignment would be the problem (I admit I'm not a treadwear genius, though) because wear seems to be uniform on the inner edges on both sides of the car.

What you describe is not unusual for the Genesis Sedan. This is especially true for the OEM Dunlap tires.

Personally, I think the alignment specs have been manipulated by Hyundai to provide more precise steering (notice I said "more precise" and not "precise") needed to fix a somewhat sloppy steering design, and that in turn causes the tire problems.

Here are photos of the outside and inside tread of the same tire.

888, these are the Dunlaps -- and I agree, they're terrible. Never thought I'd be looking forward to spending $1000+ on a set of tires. So your comment about Hyundai setting the camber to improve steering precision leads me back to one of my questions -- can camber be adjusted?

I had almost the same tread wear on my Dunlaps at 22K miles on my left front tire, but I think it was on the outside tread (but don't remember for sure).

I don't think you need to spend quite as much as $1000. Between now and Feb 26th, you can get $70 off a set of 4 Michelin's at Costco. This will pay for the $50 yearly membership if you don't already have one.

If you have 17" wheels, I would highly recommend the Michelin Primacy MXV4. I am not sure if it is available to fit the Genesis 18" wheels, but they probably have other comparable Michelin tires that do fit. Obviously, the have other brands also.

After getting 4 new tires, I went to an alignment shop that my local Costco recommended (Costco doesn't do alignments) and they did an alignment to specs, then a test drive, and then adjusted again after the test drive. Costco will do free rotations every so often (I think every 7K miles, but not sure). I never used to rotate my tires, but based on the experience with the OEM Dunlaps on my Genesis, I am going to do them from now on.

Thanks for the input. I've got 18" wheels and I'm looking at the Conti Extreme Contact DWS (seems everyone likes those) or the Michelin Pilot Sport A/S Plus (not sure if I like the unidirectional tread because of rotation).

Do an internet search on the Michelin Pilot Sport A/S plus. You will find a lot of complaints about pulling to the right. I had a very bad set of the Michelin that the tire dealer replaced after about two weeks. Many complains from Mercedes, Lexus owners and myself. search google Michelin Pilot Sport A/S pulling

I went through this same thing several months ago.

My Dunlops were practically gone at 27,000 miles, and I replaced them with Goodyear Comfortred Assurance tires. I noted that the Dunlops had excessive tread wear on the inside of the rear tires.

Shortly after replacing the tires, we were on a trip and I was following my wife, who was driving the Genesis. I observed then that the rear tires had negative camber.

In January, I took the car to the Hyundai dealer and asked them to do a four wheel alignment. I asked the service manager to give me a copy of the settings both before the alignment and after. I might add that this was the first time the car had had the alignment checked.

Practically all settings on all four wheels were changed. As far as the rear wheels are concerned, changes were made on both the camber and toe. (Caster is apparently not adjustable on the rear wheels.) The pre-alignment camber settings were -2.1 degrees on the left rear and -1.8 degrees on the right rear. Toe settings were 0.06" and 0.04" for the left and right, respectively.

The settings after the alignment were -1.8 degrees on the left and -1.7 degrees on the right. The new toe settings were 0.08" left and 0.09" right. So, changes were made in the camber; but the camber on both wheels remains significantly negative. I have not driven enough miles since the alignment to be able to see if the changes will stop the inside tire wear on the rear. It could be that the changes in the toe settings could also have some effect on this.

The Hyundai recommended settings for the 2009 Genesis (which mine is) are -1.43 degrees plus or minus 0.5 degrees. Ths would be a range of -.93 degrees to -1.93 degrees. Even at the lower number, the settings would still be negative. The toe settings are 0.0944" plus or minus 0.0393".

In all fairness, I think most (if not all) of those complaints are quite old. However, it may be that the tread pattern does exacerbate any problems with the alignment, even those deliberately introduced by the manufacturer to "improve" steering.

Post as late as Ootober 2011 that I found still having problems. Here is a copy of one from July 2011 Lexus forum.

"Does anyone else have this problem with the Michelin Pilot Sport A/S Plus?

I just got them installed yesterday from Costco but before I even ordered them, the tire guy there warned me that he's experienced these tires pulling to the right on the GS. I haven't heard any reports of this on the reviews so I chalked it up to alignment issues with those cars. But when I got my car back, going straight and letting go of the steering wheel, the car would pull to the right. Even when I tug on the wheel to the left and let go, it would eventually start to go right.

So this morning, I took my car to Lexus to have the alignment done but after they had made some corrections, it would still pull right. Any thoughts?

Great info CUMan. Thanks.

Stone -- I'm assuming you'd recommend going with the Contis..

Yes, if you get snow every year. Otherwise, either the conti DWS or the Serenity in a W rating, both are great tires and have mileage warranty. Now have 49000 miles on my 2011 Genny. 31000 on the Serenity tires with about 10 to 15k left. Only got 18,000 on the Dumflops.

We have not had much snow in NJ so in my limited experience, the Bridgestones handled it well. Down here now in SC and the Bridgestones are perfect!

I have a 2015 Hyundai Genesis. I have had three sets of tires wear improperly. The front two tires will wear significantly on the inside while the outside doesn't wear as much. I have had an alignment performed with the last three sets of new tires I have purchased. 10,000 miles ago, I purchased 50,000 mile W rated tires and put them on the front. I didn't make it to 10,000 miles before both inside front tires had wires showing through with the outside at 4/10ths or more with a straight line of wear from inside to outside on both tires. The tires are not warrantable under these conditions.
I took it to the Round Rock Hyundai service center and had an alignment performed. The camber on the left front is -0.8 and the camber on the right front is -1.0. I asked Patti Guebara (Service Advisor) and the technician who performed the alignment about the camber being in the yellow and red ranges. I was informed the camber is not adjustable. The previous alignment technician from a previous set of tires had told me the same thing (that the camber is not adjustable). I don't know how to make my tires stop wearing improperly.
Suggestions PLEASE?

I realize this is an old thread, however, I'm experiencing the exact same chronic camber problem on my right read for my 2017 G80 Ult. The first was less than 4 months following the purchase of this as a CPO from Bob Stallings (no longer a Genesis dealer) in 2019. It could have been serious if I was on a highway going 75 when the tire suffered the catastrophic failure. Fortunately, I was approaching a red light going less than 30 when it failed. Since the extreme wear is limited to the tire's interior (closes to the wheel well), this problem is not visible from a walk by inspection. The dealer replaced the two right rear tires, claimed there wasn't any mechanical problem, and told me that they did a full 4 wheel alignment with very minor adjustments. This same problem happened again this week on the exact same tire (right rear) that only had less than 7k (car was idle most of COVID since I worked from home also). I'm still in discussions with Huffines Genesis in McKinney to remediate this. This is a very dangerous and difficult issue if not fixed.
