Tire: New set of Goodyear Nordic, 205/70/15 on 6" wide wheels
Car: 1984 Pontiac Parisienne RWD, 4DR (~3500 LBS)
Impression:
Great at stopping this beast, took about 4 car lengths to bring the car to a stop from 60km/h on Barnet Hwy (Compact snow, evenly spread) by locking up the brakes. (No ABS).
They do a great job at siphoning out the slushie snow, was able to get to 80 KM/H on Barnet at 1AM, where the snow at this point is compact and the slushie bits have hardened... it felt very stable and controllable at this speed.
Also, I am very pleased with how they grip when braking whilst the car is sideways, or mid drift. The sidewall grooves do a great job at regaining control during a drift.
However, I have noticed that getting the car going from a stop does incur plenty of wheelspin. I was able to get out of every unplowed parking lot, even though its RWD, just had a lot of wheelspin - whilst modulating the throttle to keep momentum.
