Tire Size 265/75r16 vs 265/70r17
Are you considering upgrading your vehicle’s tires from the stock 265/75R16 size to a slightly larger 265/70R17? While this change may seem minor, there are important differences to understand before making the switch.
- Shorter sidewalls may provide slightly firmer ride quality and improved handling responsiveness
- Reduced sidewall height can minimally impact ground clearance for off-road driving
- The speedometer will read slightly higher than actual speed, but the difference is negligible
- Taller sidewalls of 265/75R16 tires offer marginally better protection against sidewall damage off-road
265/75r16 vs 265/70r17
The main difference between 265/75r16 and 265/70r17 tires is their sidewall height.
Fitment Guide
The overall diameters of these two tire sizes are very close, with the 265/75r16 measuring 31.65 inches and the 265/70r17 at 31.61 inches.
This 0.1% difference is well within the 3% limit for direct replacement without modifications. Both tires will fit the same vehicles without issues.
Ground Clearance
The shorter sidewall of the 265/70r17 reduces ground clearance by 13.25mm compared to the 265/75r16.
This can increase the risks of scraping or damage from obstacles. The extra clearance of the 265/75r16 is better for rough roads or off-road driving.
Gas Mileage
The 265/70r17 weighs slightly less than the 265/75r16, which improves fuel efficiency marginally.
The shorter sidewall and smaller overall diameter also reduce rolling resistance, further aiding gas mileage. This makes the 265/70r17 a smart choice for daily drivers focused on efficiency.
Ride Comfort
The taller sidewall of the 265/75r16 absorbs road imperfections better, providing a smoother ride.
The extra cushioning is advantageous on uneven or bumpy roads. However, the difference is modest, and both sizes deliver comfortable rides.
Aesthetics
The difference in appearance is subtle. The 265/70r17 will have a slightly shorter sidewall, giving it a more low-profile look than the 265/75r16.
Which aesthetic suits your vehicle best comes down to personal taste.
Handling & Stability
The 265/70r17 shorter sidewall enhances responsiveness and handling precision on the pavement.
The taller 265/75r16 sidewall flexes more, reducing handling performance slightly. However, both offer stable, responsive handling for everyday driving.
Noise & Vibration
The stiffer 265/70r17 sidewall transmits more road noise and vibrations into the cabin.
The taller 265/75r16 helps dampen vibrations, providing a marginally smoother, quieter ride. However, both tires minimize noise effectively.
Durability & Wear
The shorter sidewall of the 265/70r17 can promote slightly more even treadwear.
But differences in longevity between these sizes are negligible – both deliver impressive mileage warranties from quality brands.
Adverse Conditions
Performance in rain, snow, and off-road conditions is similar. The 265/70r17 shorter sidewall makes it a bit more responsive, while the 265/75r16 extra ground clearance is a slight advantage. Overall, both perform well in adverse conditions.
Speedometer Reading
Due to the 0.1% smaller overall diameter, the 265/70r17 causes the speedometer to read 0.1% higher than the actual speed.
At 20 mph actual speed, the 265/70r17 reads 19.97 mph on the speedometer. This negligible difference has no significant impact on driving.
What is the Difference Between 265/75R16 and 265/70R17?
The main difference between 265/75R16 and 265/70R17 tire sizes lies in the sidewall height. The 265/70R17 tire has a sidewall height that is 0.52 inches (13.25 mm) shorter than the 265/75R16 tire, which equates to a 6.7% difference in sidewall height.
Can I Use 265/70R17 Instead of 265/75R16?
Yes, you can use 265/70R17 tires instead of 265/75R16 tires. The overall diameter difference between these two sizes is only -0.1%, which falls within the acceptable range of 3% for tire replacement.
How Much Taller Is a 265/75R16 Tire Than a 265/70R17?
A 265/75R16 tire is 0.04 inches (1.1 mm) taller than a 265/70R17 tire. The overall diameter of the 265/75R16 tire is 31.65 inches (803.9 mm), while the 265/70R17 tire has a diameter of 31.61 inches (802.8 mm).
Our Observation
Our observation is that while the 265/75r16 vs 265/70r17 tires differ mainly in sidewall height, they deliver comparable overall performance.
We found the 265/75r16 absorbs bumps better and has more off-road clearance, but the 265/70r17 offers marginally improved handling and aesthetics.
For most drivers, either tire size provides an excellent balance of comfort, responsiveness, and capability.
The differences are modest, and both sizes can be considered very capable all-around tires. Choosing between them comes down largely to individual priorities and vehicle fitment considerations.
