INTERNATIONAL HARVESTER 1056 TIRES
The International Harvester 1056 tractor, equipped with 2WD and standard agricultural tires (7.50-18 front, 18.4R34 rear), excels in stability and traction for large-scale farming tasks. However, the 2WD configuration may limit performance on uneven terrains, increasing the risk of slippage in wet conditions. For optimal use, it's best suited for flat fields or well-maintained surfaces where weight distribution and tire size can maximize ground contact for better efficiency.
