Old runflats and hit a pothole.. Strange sounds coming from the tire.

Hey guys.



I have 30k on my runflats. I know that's way too many miles. I was actually going to trade my car in at the end of the year so I was holding off...



Anyways I was driving home tonight and it was really dark and I must have hit a pot hole because it sounded horrible and my low tire pressure light for my front right tire came on. I pulled over but there are very few lights where I was and it didn't even look like the tire was flat.



So as I got closer to home I put my windows down and noticed on every rotation it was making a horrible screeching sound, very loud also. I got home and it's still way too dark but the tire didn't look that low and I couldn't see any other damage. Anyone know what the screeching sound might be, could something else have broke when I hit the pothole?



The car seemed to be driving straight and I will take a closer look in the morning but if the tire isn't flat what the hell is making that screeching noise? Any ideas?



Thanks
