Commercial ply is stronger than normal ply. Waterproofed ply is waterproofed and commercial ply is stronger but not necessarily waterproof.
A playlet is a short play! :)
23.5-25 is bias ply tire 23.5r25 is radial tire
The difference between 8-ply and 4-ply wool, can depend on the weight of the plies. Some 3-ply yarns have heavy weight (fatter) plies, which knit up heavy worsted, where 2-ply lace weight yarn plies are much lighter (skinnier) plies that knit up very light/lacy/small.If I were to guess, the 8-ply in question, may have smaller plies than the 4-ply. I think if you double the 4-ply, that would be too much. You should try a gauge swatch using the 4-ply singularly, and maybe adust the needle size.
Radial tires are worlds beyond bias ply tires. In radial tires, the steel chords are placed in a criss-cross pattern. Whereas bias ply tires are placed flat across the face of the tire. Bias ply tires are much, much harder for the engine to turn and are much harder for the suspension to compensate for. Bias ply tires are almost no longer used. That goes for America at least.
It is Plies.
The ply of a tire is independent of whether it is run-flat. There are many different run-flat technologies but most deal with some sort of "self -healing" gel liner or coating. The ply of a tire can make a difference in whether the sidewalls of a tire could stand up tall enough for you to drive off but that's not considered run flat and is coincidental to each tire and could only be estimated by doing it. Which i wouldn't if you value the sidewall.

Yes. A ply is a layer so 2 ply is double as strong as 1 ply
The load range indicates the ply rating of the tire or the number of plys under the tread. A = 2 ply B = 4 ply C = 6 ply D = 8 ply E = 10 ply F = 12 ply G = 14 ply H = 16 ply J = 18 ply L = 20 ply M = 22 ply N = 24 ply This has a direct relation to the Load Index which tells you the weight the tire can carry. The more plys the more weight the tire can carry.
The term 'Tool of Trade' in regards to commercial vehicle insurance means the vehicle is needed to ply the trade (transportation of equipment, etc.)
it depends on the ply. such as two ply or one ply.
Radial tyres have much better stability, better road surface contact, better handling, more comfortable ride and lighter. Most commonly used on road cars. Cross ply are cheaper and stronger, better grip for off road use i.e. tractors. They are the predecessor to radial tyres on cars.
