off topic / traction control

[Programmer]

Hmmm....that seems ag'nst all logic. Normally, you lower tire pressure for
traction and the result is also instability <g>. They had balance harmonics
in those things  that resulted in the inability to get the vibration out of
the chassis at 34 psi pressure. They found that lowered tire pressure took
out the vibes--and gave you a smooooth ride. Unfortunately--this also
creates more tire heat.
