More tread depth translates to better traction and grip, which is crucial when towing heavy loads or navigating through challenging conditions. I can already imagine the enhanced driving experience, with improved control and stability, allowing me to confidently maneuver my trailer wherever my adventures take me.
Moreover, the heavy-duty nature of these tires, rated at 10 ply, ensures that they can handle significant loads without compromising performance.

I wanted a tread pattern that would provide stability and grip, especially when towing heavier loads.
