OE WHEELS that come standard on e53

[ake53]

hello everyone.
My X5 is at 93,000 miles and the wheels have half more than half thread left.

Now the problem is... I inspected and noticed many cracks near rim, I mean that's normal. BUT than i see horizontal cracks going down the sidewall!

I suspect this is because the tires must have been under-inflated 10 psi by the previous owner?

My co-worker told me that they be under warranty... but I don't have documentation to prove they were recently purchased by last owner...

So than maybe there's a recall on this model of Michelin wheels?
Michelin Energy MXV4 Plus Grand Touring All-Season

Any know anything about this? or should I contact Michelin.

I'm just worried of driving and having the tire blow on me. and than anything could happen.

Thanks for your inputs on this thread...
