The 5.50/16 tire size is of an agricultural tire that’s designed for use on the front wheels of smaller to medium-sized tractors used in general field service. For tires like this, you need something that can resist damage caused by debris, stubble, and driving impacts, and has a solid rubber compound that doesn't weather or crack. Typically, the 5.50/16 tires feature a symmetric ribbed tread pattern that helps in improving steering, stability, and even weight distribution and minimizes soil compaction.
