Tire pressures are based on a combination of car weight needs, capacity for weight and to an extent ride. On the side of every tire is an air pressure range stamped to the tire that tells you what the tire maker requires in it to be safely used. This is the best method of choosing because there could be a difference in the tire the factory had on it and the ones you have. Many factory tire pressures on tires these days are near 42 psi cold though so I would question 24 as this is considered flat in most over the road tires!
I think that is low for the tire casing.
If the tire is big, and the axle weight is light, the sticker can confuse you because it was for the factory fit.
Have the tire makers guys look and question usage.
Some oversized usage can be reduced, but ask them the tire's minimum.
The sidewall will have max pressure at max weight load, and harshest desert environment expressed for the longest number of minutes it could last.
You want to run it your way, in your climate, the way your vehicle gets loaded.
Lets not forget the Ford explorers that said 25 psi, fellows.
In our experience, 24 pounds is way too low for a 60's mussel car which had glass-belted tires from the factory when the car was new. Call the dealer of the car and ask them what the tire pressure should be with or without radial tires.
24 pounds is way too soft if you have radial tires which will cause them to overheat and fail on a heavy powerful muscle car.
Yes, 24 seems right, lots of Mopars were 24-26psi in the late 60's. You have to remember thats the old bias belted spec tire, and muscle cars had larger tires than the base models they were derived from... They weighed much less for their size...todays Honda accords weigh about the same as an early Roadrunner.
if you are not running retro tires, 24psi may not do. You need to get load capacity figures, for the p metric tires and do the math...
Check on the tires for the recommended pressure. Cars that have been modified or updated usually don't have tires that are original to the car, so you should follow the tire manufacturer's specification.
Curious. There are not too many passenger vehicles on the road that only call for 24 psi recommendation. You can double check your recommended PSI here:

If it matched the size you have fitted then it would be correct.
The decal says the tires should be at 24 psi. Is it too low? It's a muscle car if that helps.
