Air pressure of rear tires with calcium chloride -12-14 lbs?

A while back, I thought i saw a thread about the proper inflation pressure for tires loaded with calcium chloride. I believe it said 12-14 lbs. Can anyone confirm this? One tire on my 1948 8N is low after sitting for the winter, and i don't want to overfill it. Thank you,
 
I run 12 pounds in my rear tires with CaCl in them.
If it is leaking, fix it NOW instead of just adding air.
CaCl will rust out your rims if you let it leak.
Fix it quick and the rim will still be serviceable.
 
I agree with fixing it now.
CaCl will eat your rims if a leak is left
unattended.

couple of weeks ago because of rust through
in a few places.

I like to run 10psi with CaCl filled tires. Higher tire pressure will increase tire longevity - especially if you travel on pavement - but will decrease traction and make for a bouncier ride. Lower tire pressure will soften the ride and increase traction but will decrease tire longevity on pavement.

Tire inflation depends on the size and type of tire. Get out your Operator's Manual as there is a chart in it. It shows proper tire inflation for various tire treads and the proper Calcium Chloride capacities as well. Rear Wheel tire size 10-28 (nowadays 11.2 x 28) 4-ply, 12 PSI at 1575 max load, 14 PSI at 1720 load per wheel. As talked of already, if you have a leak, chances are Ca Chl is leaking onto the inner rims and will eat thru them soon. If you want to save them, especially if they are the original hat rims, fix the problem now. Take them to your local AG Tire Center and let them do all the grunt work -well worth the $$$ IMHO, as they have the hi-tech equipment to do it. Could just have them drain and dispose of the stuff if you don't need extra ballast. A further option is to replace with non-corrosive Beet Juice (Rim Guard) if you want/need ballast. Ca Chl was used back then because that was all that was available. If replacing, use new tubes. You may get lucky and it is only a faulty valve stem, but why guess.
