I recently purchased a Nissan Sentra XE and noticed that the recommended
tire pressures were 32psi for the front tires and 29psi for rear tires.
With my earlier car (an ’83 Toyota Corolla) I remember the recommended
tire pressure for the rear tires were higher than for the front ones.
(Don’t remember the exact figures)
I have driven motorcyles, and I remember that the rear tire pressures
are always higher than the front ones.
Basically, I am surprised at the figures for the Sentra, so could someone
explain how this could be correct?

In a nutshell, having the front tires with higher pressure causes a car
with the tendency to understeer to be more neutral.
If you think about it, the rear tires (with low pressure)
will have more surface area (and friction) and tend to "follow" the front
wheels. Reversing this would cause a car with inherent oversteer to be
made more neutral. Most cars I’ve had have higher pressure in the front
tires including my ’94 3000GT. (33 PSI front, 29 PSI rear).

Rob; You have that Bass Ackwards
If you give the Rear Tires lower pressure (more traction) then they will
slide less….wich contributes to understeer/push.
High pressure rear / low pressure front = More Oversteer/Loose
Low pressure rear / high pressure front = More Understeer/Push
