RENAULT 551S TIRES
The Renault 551S tractor offers both 2WD and 4WD configurations, allowing versatility for various applications; however, 4WD enhances traction on uneven terrain, making it suitable for more demanding fieldwork. The standard rear tire size of 14.9-28 is compatible across both configurations, maximizing interchangeability, but the 2WD may struggle in wetter or more challenging conditions compared to the 4WD variant. Consider the front tire options: larger 11.2-24 tires on the 4WD can improve flotation and grip, making it a better option for farming scenarios where soil compaction and traction are critical.
