VALTRA N155 TIRES
The Valtra N155 is equipped with standard tires of sizes 480/65R28 (front) and 600/65R38 (rear), which provide a good balance of flotation and traction for general agricultural use. Optional tire configurations, such as 380/85R28 and 460/85R38, offer better maneuverability in tight spaces, while sizes like 540/65R28 and 650/65R38 can enhance stability and load-bearing capacity for larger implements. Consider the terrain and intended application; narrower tires may be preferred for row crops to minimize soil compaction, whereas wider tires could be advantageous for heavy-duty field tasks.
