16.9 by 30 if the rim is 30 inches
for traction
To provide more traction.
The size of the rear tires on the Cub Cadet 1641 garden tractor are 23x10.5-12. The size of the front tires are 16x6.5-8. The wheel base on this tractor is 46.5 inches.
If they are regular tires and the tractor is 2wd they are 11.2-24 and 4wd they are 9.5-24 If they are turf tires and the tractor is 2 or 4wd they are 41x14.00-20
No But It can be done and will increase traction
The torque which is to be transmitted in the tyres defines it
As the tractor pulls plows or other things the weight gets pulled back onto the rear wheels, to carry that weight and not sink into the ground they need to be large.
It is more difficult to steer with big tires, they are smaller so they are managable, also the weight on a tractor and traction is needed in the rear
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.
The pressure in any tire is determined by the weight the tire is supposed to carry . For example , if a car is weighing 2000 kilos , each tire is carrying 500 kilos weight . The pressure in the tire should be such as to withstand this weight . Pressure is force divided by area . So the more the area of the tire connecting to the land , the less tyre pressure is needed to withstand the weight . The rear tires of the tractor are almost double the size of the front tires and carry three fourth of the weight of the tractor . So if the tractor weighs 2000 kgs the rear tires carry weight of 1500 kgs and the front tires carry weight of 500 kgs . But then the front tires are one half the size so the pressure there will be 2 X pressure in rear tyre X 3/4 . ( These are approximate calculations for illustration . ) So the front tire should have about 1.5 times more pressure than the rear tires .
the definiton of tractor is easy. Here it is: A vehicle having a powerful gasoline or diesel motor and usually large, heavily treaded rear tires, used especially for pulling farm implements or machinery.
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.
