Help needed!!! (Especially for those whose car came with Michelin’s)
So we are coming up on a year that my wife has had her G82. She won the “tire lottery” and it was fitted with the PS4’s. Today, she calls me and asks me to take a look at her tires as they are making a funny noise. I was shocked to see that the rears were not only down to the cords…but the rubber had come through in one spot. How could this be on a car with less than 8k miles on the clock. Obviously, my wife isnt doing Smokey burnouts or anything like that. Could the lowering springs have caused this? I’ve never seen anything like it…

that is some serious wear, interested to know if there is anything rubbing on the tire. Is it only on that one tire?

Was the alignment checked after lowering the car?

I've driven 40K miles plus with Michelin PS4's and never had issues or seen anything like that. Obviously that 40K miles included a swap out of new tires. I think the tires are rated around 30K.
I bet your wife ran over something in the road that contributed to the tread separating like that. Very lucky it didn't cause damage to the car. My wife ran over two nails over the life of the tires and I had to get them fixed but the tread never separated. Edit: The 40K miles included stock height and lowered via KW HAS and no issues.

here are all 4. the driver rear is showing a lot of inside shoulder wear....but it also seems like the wear is a bit excessive over the whole tire for such little miles. especially when compared to the fronts and considering that my wife is really leaning on the car that hard....

I assume RWD?
Not that it should matter after only 8k miles, but there are different compounds across the flat of the tire. I found this out on my F82 when my fronts were showing threads on only the inner edge of the tire, while there was plenty of tread left across the rest of the tire. I didn't know what was going on at the time because there was nothing wrong with the suspension or alignment, but then I watched a video on Youtube about the *STAR* tires and how they're made. And that's where I discovered there are several different rubber compounds across the tire, which would explain the wear. But, this was after 24k miles, not 8k. Edit: Yeah, just saw your updated pics... probably not the same experience.

thats EXACTLY what i was thinking. maybe a valet or something. but i checked inside the wheelwell and there's no excess rubber like you'd expect from doing burnouts that would damage the tire that much..

Because I'd hope you'd be able to sense a really bad rear alignment while driving, the pictures determined that statement to be a lie. Tires are also wearing like they're underinflated.

Overinflated rears? What's your cold pressure?

Doing some searching it appears even though the tires are rated at 30K they are more like 12-20K tires. I think I got close to 20K now that I think about it (wife commuting on the freeway). I was at 50K miles and had changed the tires out twice from the stock Super Sports to the PS4's. I'm seeing 11K, 12,500K and 15K miles searching on google.

Yea, the premature wear on those rears compared to fronts are not suspension related. The rears have been lit up a more than a few times lol. You do have camber wear, more than stock, but expected on a drop and maxed out camber OEM adjust.
Honestly, the disparity is too much without burnouts. And YES, replace ASAP. Its actually illegal to drive with those rears, insurance may even negate coverage due to the tire condition in case of an accident where control is lost. Thats what I have heard in my state at least (FL). |
