It doesn’t matter if you’re on a dyno and you’re not actually going anywhere. Tires have a speed rating for a reason, kids.
On this last-generation Mustang, the tires clearly weren’t rated for a simulated 150mph. At the top of 5th gear, the tires explode—and take out the quarter panels, the supporting metal underneath, the rims, and nearly the gas line, which would have resulted in a completely different story.
Nobody was hurt except Bandanna Man’s pride. Watch as the rear bumper goes flying off like a mortar shell.
