Actually, heavy braking would tend to loosen knock-offs wouldn't it? For
both sides, the top of the knock-off has to be rotated forward to loosen it.
When driving forward that's the direction the top is moving. Then when you
brake, the top is going to want to continue in that direction. Acceleration
would tend to tighten them. However, since virtually all cars can shed speed
much faster by braking than then can add speed by accelerating, there must be
another reason for the right & left hand threads setup the way they are. Or
maybe they were designed by Firestone.
