Goodyear F1 All Season's.
I only say that because a couple of times I have hit potholes that sounded and felt like I was going to leave half the suspension behind me! I did the normal routine......pull over fast because you just KNOW you're gonna have a flat tire and busted wheel. Major astonishment when I found no damage whatsoever!
BTW.....Here in Michigan......we are masters of cultivating potholes!
For your amusement......
