Re: anybody know proper tire pressure on a 1929 6.5-20 tire?

A 6.5 x 20 would be a bias ply tire. I'm not aware of what pressures Packard might have recommended.

One approach would be to get a recommendation from the tire manufacturer.

Another approach would be to compare the vehicle weight including gas, oil, water and a typical passenger and baggage load to the maximum weight carrying capacity of the 4 tires, as marked on the tire. As the two weights approach each other, the inflation pressure should approach the maximum pressure needed to bear that load. That information should be molded into the tire sidewall.

As mileage accumulates, check the tread wear pattern for signs of under- or overinflation and adjust pressure accordingly.
