The Yokohama 504C is a commercial tire that's designed for use on all positions, including the ster axle, of semi-trucks in on- and off-highway applications. Wide grooves promote self-cleaning for consistent traction, and the 504C's large footprint puts more rubber on the ground to enhance traction and braking performance while also fending off uneven wear. Funnel shaped grooves force stones out of the tread to protect the casing from damage, and the 504C's steel belted construction increases load carrying capacity while also guarding the tire against cuts, chips, and abrasions.
