[Tigers] Found the pressures

[mwood24020 at aol.com]

Lots of variables in determining optimal pressures f/r. If you want
best performance, drive the car on a skidpad with sidewalls chalked (to
determine rollover) and take temps with a pyrometer immediately. You
are looking for as close to uniform temps as possible across the tread
and roll over just past the edge of the sidewall. Of course, front
alignment is going to factor into this testing, as well.
Ball park for a 2500lb car on normal tire fitment (which seems to be
too much section width for given rim width in the Tiger community) and
any of the modern performance tires is likely to be low 30's, with the
fronts a couple of psi higher. The recommendations by Tire Rack tend to
be biased towards new OEM fitments, which are quite often for lower
rolling resistance type tires with much higher pressure requirements..

That was for bias ply tires in the late 60's. Ron's right (imho), look
at
the tire and adjust the pressure accordingly.

And Tire Rack is probably close to being right for modern radial tires.
@
35 psi, I think, may be close.
