Re: Tire pressure?

The pressure Packard recommended was 24 pounds cold which is a bit low in my opinion and like a lot of other cars, probably specified with a lower pressures for comfort. I would not think 30 is too high but again it depends on the tire and it's maximum pressure rating, driving conditions and how comfortable you are.

The inner tires, or as we call them inner tubes, were very common up until the mid to late 50's. A lot of the wheels of the time could not hold air for tubeless tires because of the way they were made so the inner tube was necessary. Some may have kept using them mostly from habit long after they were no longer needed. 56 Clippers came standard with tubeless tires so am not sure why yours would need tubes unless there has been damage to a wheel so it won't hold air or maybe the tire is punctured in a place it can't be patched to hold air or the last owner just felt more comfortable having them.

I am not familiar with your tires but for the last several years over here, there has been a date of manufacture required to be cast into the rubber along with other information such as tread life, service rating, max pressure and so on. Is there any sign of something like that on yours.
