Why are the rear tires of a tractor bigger than the front tires?

   Big tires are expensive, but it all comes down to traction: they wouldn't be used if they were unnecessary. A tractor needs big rear tires for pulling equipment and to help keep it from getting stuck in muddy fields: those big lugged tires are great for pulling plows and harrows through the soil. However it does not need all tires both front-and-rear (usually four) to be the same size, as the front are used for guidance and the rear for traction. Some tractors use twin rear tires instead of a single one (thus making four rear tires) for even greater traction especially when filled with water.
