Chris Harris commits spare tirecide.

When you equip the Mercedes-Benz C63 AMG with the available Performance Package, the car sends some 480 horsepower to the rear wheels. Even when those rear wheels are shod with sticky, 255 millimeter-wide tires, traction is a potential challenge. Leaving the electro-nannies on is a good idea for street driving, and it’s probably in order for less-than-experienced drivers on the track, too.

What if you replaced those rear tires with 125 millimeter temporary spare tires? In fact, what if you replaced all four wheels and tires with temporary spares, then let an experienced motojournalist like Evo’s Chris Harris loose on a racetrack? The combination would either be a recipe for big fun, or a recipe for disaster, depending upon your perspective.

We won’t spoil the outcome, but we’ll tell you that you’ll want to watch the video below. We’ll also tell you that we’re phoning junkyards to stir up three other temporary spares for our own rides.
