If all else were equal except the tires, the distance between them would have stayed the same after swapping the wheels/tires.

But the gap between the cars shrunk slightly. When the ForkenSwift was wearing the snow tires, it came in 18.3 m / 60.1 ft behind the Blackfly. The Blackfly, wearing the snow tires, rolled to a stop 15.9 m / 52.1 ft behind the ForkenSwift.

I wasn't surprised to see both cars roll further in the second set of runs. Likely because the tires were warming up throughout the testing. (In almost all cases, each successive run was a little bit longer than the previous one by a couple of feet. I took an average for each set.)

Overall the tests took nearly 4 km of driving (both cars going exactly the same total distance).
