285/70r17 vs 265/75r17
Our Observation
Analyzing the data reveals that while differences exist between the 265/75r17 and 285/70r17 tires, they are generally minor. The key variance is in width, with the 285/70r17 being 0.79 inches wider. This does provide a larger contact patch and traction advantage.
However, the more narrow 265/75r17 promotes slightly better hydroplaning resistance and fuel economy owing to lower rolling resistance. All other metrics like diameter, circumferences, and sidewall height are nearly identical at under a 0.2% difference.
These subtle variances lend the wider 285/70r17 to stability-focused applications like trucks. At the same time, the narrower 265/75r17 fits lighter-duty vehicles needing efficiency.
However, both deliver comparable overall real-world performance in critical areas like ride quality, ground clearance, handling dynamics, wear life, and drivability. Either tire size works well in OEM applications or as a replacement.
Given how minor most differences are, I’d recommend selection based primarily on vehicle fitment constraints, intended usage, and driver preferences rather than strict performance advantages. Neither option clearly outshines the other holistically, making both suitable choices depending on needs.
