I have an 2006 MCS with 11K miles on it, I bought it with 3k. I have had it about 6 months now. The tires seemed to be slightly dry rotted when I got the car but since they only had 3k miles on them I figured I would let it ride for a bit. Well I noticed the road noise got worse so I took a good look at the tires today and found the inside edges of the tire worn extremely bad to the point I see the belting.

The tires are Dunlop SP Sport 9000 run-flats on 17 inch stock wheels. My question is should I be concerned about alignment/suspension problem or contribute it to the dry rot causing them to wear bad. I am not a crazy driver but do drive spirited from time to time.

I did a search and found some threads on the inside wearing but this seems to be both inside and out (inside definitely worse).

below are some pics:

 

Yep, you got an alignment problem. At least now you have an excuse to replace your run flats, right?

 

Underinflated tires wear both edges.

 

OK - just checked... they are under inflated.

Yes I hate the runflats so I guess I am officially tire shopping. I see a ton of threads about tires after a search so I guess I gotta figure out my budget.

Thanks for confirming the alignment issues!

Good thing they were runflats, because it looks like you ran them flat for a couple thousand miles. Better check your pressures more often than never.

Regular tires are much better for ride quality, so at least you get something for your money.
