I'll post them here first, because I'm nice
Here is the worse one I pulled off this morning. I first noticed a small bubble in the outer edge of this tire's tread Sunday evening, and have driven no more than 20 miles since then.
Close up. Notice how the tire is ripping. It is following the cracking along the outer tread block.
Another close up
The other 2 are my other front tire and driver side rear. The front tire has a small knot like the one above first exhibited. The rear tire is swelling along the inside, where (no surprise) the cracking is. It stretches along maybe 25% of the tire's circumference.
