Did the Biden's Beast have a breakdown?

Sorry: Audio only for speed.

I heard something strange at 8:22:00 in the CSPAN coverage, so I pulled up audacity to enhance the sound. You can clearly hear one male saying "Damn. Ready?" followed by a different male speak into his radio "Yea. Go ahead and send the other Beast over." A few seconds later, a female is heard saying "(inaudible)...my tires ran over it."

I thought the Beast had runflat kevlar reinforced God-tier tires. Did the Beast really get a flat, or did something happen during the weird CSPAN logo cutout a few seconds later?
