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.
depends on the size of the tractor
for traction
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
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
Tractors have small tires on the front to make it easier to steer the tractor. Large tires are harder to steer. The large tires in the back allow the tractor to have more power as it plows.
The torque which is to be transmitted in the tyres defines it
U Can Use Tractor tires to run A farm Tractor
The front wheel(s) are only for steering and holding the front end up. The back wheels supply the power and must have traction. Making them big lets them carry big tires which keeps the tractor from getting stuck in muddy fields and keeps them from slipping so easily. The big lugs on the tires also help in that regard.
