Fitment Guide

The 265/70R17 tire is 3.2% larger in overall diameter than the 265/70R16. Replacement tires should be within 3% of the original size to prevent clearance issues.

The larger 265/70R17 may require small adaptations like a leveling kit to avoid rubbing at complete turn. The 265/70R16, being smaller, is more likely to fit without modifications.

Ground Clearance

With a diameter of 31.61 inches, the 265/70R17 provides 1 inch more ground clearance than the 30.61-inch 265/70R16.

This added clearance aids off-road driving by reducing scrapes over obstacles. However, the larger 265/70R17 diameter causes a lower speedometer reading than the 265/70R16.

The smaller 265/70R16 diameter increases the risks of scraping but gives a higher speedometer reading.

Gas Mileage

The 265/70R16 smaller contact patch and lower rotational mass improve fuel efficiency compared to the 265/70R17.

The larger 265/70R17 diameter and width increase rolling resistance and weight, negatively impacting gas mileage.

Ride Comfort

The 265/70R17 taller sidewall absorbs road impacts better, providing a smoother ride over uneven terrain.

The shorter 265/70R16 sidewall transmits more harshness over bumps but offers a tighter on-road feel. Overall, comfort differences are minor between the two.

Aesthetics

The 265/70R17 has a slightly taller sidewall, giving it a more rugged, aggressive look suited to trucks and SUVs.

The 265/70R16 shorter sidewall has a lower-profile appearance that some vehicles suit better aesthetically. Overall, visual differences are subtle.

Handling & Stability

The 265/70R16 shorter sidewall enhances responsiveness and handling precision on the pavement.

The taller 265/70R17 sidewall flexes more, reducing handling sharpness slightly. However, both provide responsive, stable handling for everyday driving.

Noise & Vibration

With its stiff sidewall, the 265/70R16 transmits more road noise and vibration into the cabin. The 265/70R17 extra sidewall flex dampens vibrations better for a smoother, quieter ride. Differences are minor between the two sizes.

Durability & Wear

The 265/70R16 smaller size could allow for slightly more even tire wear and longer tread life. The heavier 265/70R17 may introduce more wear on vehicle components like wheel bearings.

Adverse Conditions

The narrower 265/70R16 can cut through to the pavement more effectively in snow and ice.

The wider 265/70R17 provides better traction in specific off-road conditions. Overall, both perform well in adverse conditions.

Speedometer Reading

At an actual speed of 20 mph, the speedometer reads 19.37 mph for the 265/70R16 and 20 mph for the 265/70R17. This 0.63 mph difference is due to the smaller 265/70R16 diameter.

Can I use 265/70r17 instead of 265/75r16?

Using 265/70r17 instead of 265/75r16 is not advised. The diameter difference exceeds the recommended 3% limit, with a 3.3% variance (1 inch or 25.4 mm).

This may affect speedometer accuracy and handling. It’s crucial to maintain similar diameters for optimal performance.

What does the 70 mean on 265/70R17 tires?

The “70” in the tire size 265/70R17 refers to the aspect ratio of the tire. It means that the height of the tire’s cross-section is 70% of its width.

In this case, for a 265/70R17 tire, the sidewall height is approximately 70% of 265mm, which is about 185.5mm.
