Tires filled with???

I replaced a tire a couple of years ago on a tractor for somebody.It had a large spout for a valve stem.It was filled with a tan colored powder,I kind of thought it was lime but smells and tastes like sheetrock,(gypsum)The tractor is a 601 Ford that was brought down to N.H.in the mid 60's from northern Canada.I assumed they used the powder as ballast because of the cold up there.What was used back then to fill the tires? We have all guessed gypsum,but that's all it is,a guess.
 
ground talc my brother had a CA Allis Chalmers with ground talc for ballast in the back tires. Randy
 
In about 1968/69 Dad took the tractor tired to the Firestone store.
They broke the tire away from the rim on one side and shoveled powdered lead in.
It was a light pink color.

And nobody wore any mask or gloves, etc. as they worked with the stuff nor when they tried to get the tire to re-seat on the rim.
They used a wet blanket thrown over most of the rim to help contain the cloud of lead while airing it up.
 
Wouldn't it wear the tire out from the inside while sliding around? And as far as getting rid of it, scrap lead has good value, we don't have any smelters anymore, remember?
 
There used to be several asbestos mines in northern Quebec and Ontario. People didn't think asbestos was dangerous in the 60's.
