tractor usually works in the mud,the tyres are designed big and with a lot a curves so that it does not get stuck up in the mud

Similar to wearing studs at the bottom of your soles. Gives you better traction of course. Especially necessary in the case of the tractor as it 'works' against a pulling load (the plough), which is exerting an equal force back stopping the tractor from moving.
The large treads eat into the soft soil giving the tractor some traction. The wide tyres increase surface area so that the tractor does not 'sink' in into the soft soil.

A tractor is designed to pull strongly at low speed. The front tires are small because they only guide the tractor and don't carry much weight. The rear tires are heavily weighted by being filled with water, or a calcium carbide solution in freezing climates. In addition, weights may be added at the axle. These can be steel disks or even concrete. This weight gives the tire enough traction to pull, but with that much weight it must be large so it doesn't sink in and can roll over rough ground. The force needed to turn the wheels needs to be balanced by a force to keep the front wheels on the ground, so weights are often added in front of the tractor. The tread itself is designed for what it does--paddle-like ribs in back designed for best traction, and simple straight grooves in front for steering.

the rear wheel is larger because in tractors we need more torque and traction and as most of tractors are rear drive, the traction is made at the rear wheel so as the wheel diameter is bigger the traction is larger (also the soil compaction will rise too!).
the front wheels are mainly used for steering and the smaller wheels are easier to control between rows.
Also pay attention to the grooves on rear wheels. The way they are designed, helps to get better traction and if you install the tyre visa versa will affect the traction!
Also there are tractors with large rear and front wheels and they are 4WD tractors.

through trial and error, it has been found to have the best traction while not clogging up the tread with mud.
