Re: Tire Pressure

I've got 820-15's on my 5406, and according to the Packard service adviser update, the correct inflation is 22/20. I recall the original spec of 24/24, which provided a noticeably harsher ride (esp. over bumps and pavement irregularities) with no improvement in handling...very un Packard like!

There's no harm done keeping the tires at 24 if you like that pressure, you typically get better MPG and handling with higher pressures, as well as improved tire life, although the couple of lbs. we're talking about would probably provide negligible results, especially if you only use it as a Sunday cruiser.

As a FWIW, if your car is original and you prefer firmer handling (these cars actually handled well given their size and weight), then it might be worthwhile to change out the bushings in the suspension and install new shocks.
