When replacing tires, the new set should be within 3% of the diameter of the originals to avoid issues. The 265/75r16 and 235/85r16 differ by only 0.2% in overall diameter, so fitment isn’t a concern.
With a diameter of 31.65 inches, the 265/75r16 offers 0.08 inches less ground clearance than the 31.73 inch 235/85r16.
This minor difference has little impact on off-road clearance but slightly reduces the risk of scraping on the 265/75r16. It also causes a negligibly higher speedometer reading on the 265/75r16.
The 235/85r16’s narrower tread face and shorter sidewall make it slightly more fuel-efficient than the wider, taller 265/75r16.
Less rubber on the road means lower rolling resistance, while less sidewall flex reduces energy loss. For highway travel, the 235/85r16 maximizes miles per gallon.
Both tires deliver comfortable rides, but the taller 235/85r16 sidewall absorbs bumps and impacts better. Its extra cushioning smooths out imperfections, especially on uneven terrain.
The 265/75r16 provides a firmer, more responsive ride that can jitter over cracks and potholes.
The 235/85r16’s taller sidewall visually gives it a stretched look compared to the 265/75r16. This elongated aesthetic suits the rugged styling well for larger trucks and SUVs.
However, on sportier vehicles, the shorter sidewall of the 265/75r16 can better match aggressive, performance-oriented designs.
Handling & Stability
With a shorter, stiffer sidewall, the 265/75r16 offers sharper handling and cornering response on pavement compared to the flexible 235/85r16.
But both remain stable at speed and resist deflection from impacts or load changes. The 265/75r16 delivers an agile, nimble feel for rewinding roads.
Noise & Vibration
The softer 235/85r16 dampens noise and vibration transmitted into the cabin better than the 265/75r16. Its extra air volume and sidewall flex help isolate bumps and road imperfections. But both tires keep the interior reasonably quiet and comfortable on most road surfaces.
Durability & Wear
The 235/85r16’s narrower tread face distributes contact stresses over less rubber, concentrating wear in a smaller area. The 265/75r16 disperses forces over more tread, slowing wear.
Both exhibit even wear patterns and long tread life barring alignment issues or damage.
Performance in rain, snow, and off-road is comparable between the two. The 265/75r16’s shorter sidewall responds slightly quicker on loose surfaces, while the 235/85r16’s extra clearance aids deep snow or mud. But both handle adverse conditions reliably.
The speedometer reading is very similar between 265/75r16 and 235/85r16 tire sizes. At an actual vehicle speed of 20 mph, the speedometer reads 20 mph with 265/75r16 tires.
For 235/85r16 tires, the speedometer reading is 20.05 mph at the same actual speed of 20 mph. The difference in speedometer reading between these two tire sizes is minimal at just 0.05 mph. Overall, these two tire sizes produce nearly identical speedometer readings.
