Acctually tractor tires are not filled with water but sometimes with calcium chloride, refered to by some as 'fluid'. This fluid adds weight for the tractor by reducing the use of heavy and cumbersome mounted weights.
Nitrogen is filled in aeroplane tyres.
There shouldn't be any water or antifreeze in a tire! They are filled with air, not liquid. Antifreeze/water mixture is commonly used in tractor tires for extra weight to increase traction
Because the front tyres are used to actually steer the tractor, whereas the rear ones typically are not. Thus, it's important to ensure that the front tyres have enough clearance to where they won't rub against the frame or other components of the tractor when they're turned.
If it's just the rear axle which has dual tyres, then the answer would be six. If both axles have dual tyres, then eight.
The torque which is to be transmitted in the tyres defines it

A tyre being pneumatic simply means that the tyre is air-filled, as opposed to solid, or filled with something else - meaning that almost all car tyres are pneumatic tyres.
They use air filled tyres, which is why you see them getting punctures.
Air is the best option, then use bolt on wheel weights for ballast. I live in Northland in New Zealand, I guess we're lucky, we use water ballast in tractor tyres, and it never gets cold enough here to freeze.
Its because suspension will be decreased leaving matter in the air inside the tyres making sure that the driver doesn't feel too much of a bump!
Assuming you're talking about the tyres... The tread on the tyres channels water away from the wheels - allowing the tyres to grip the road better than if the tyres were completely smooth.
You can fill them with water. If you are in an area that freezes you will need to add anti freeze or a tractor dealership may have another additive. The tool to fill them attaches to a garden hose. Most dealerships sell them.
