The best info I have seen concerning the radials on an old
car (pre 71 for most US) is that they are harder on the
suspension components than bias ply tires.  The radial
transmits bumps around the cross section of the tire
and so there is much less area to absorb the shock
which is immediately transmitted to the bottom of the 
wheel.  In a bias ply tire the bumps are transmitted
around the circumference of the tire and so more of the
road shock is absorbed by the tire and not transmitted
to the wheel.  I have not had any knowledgeable source
indicate any handling troubles.....only faster
wear on ball joints and suspension bushings.

I hope we can get a tire engineer or suspension engineer
in on this because I too would like to know!!
