Tire Size 285/70r17 vs 265/65r17

The main difference between the 285/70R17 and 265/65R17 tires is their sidewall height. The 285/70R17 has a taller sidewall at 7.85 inches (199.5mm) versus 6.78 inches (172.25mm) for the 265/65R17, a difference of 1.07 inches (27.25mm).

This means that the 285/70R17 tire has a taller sidewall, which can provide a more comfortable ride and better off-road performance.

Look at this comparison table to help you understand the difference between these options quickly and easily.

Fitment Guide

The new set should be within 3% of the original diameter when replacing tires to avoid clearance issues or speedometer inaccuracies.

The 285/70R17 diameter is 6.6% larger than the 265/65R17, exceeding the 3% limit. The taller 285/70R17 may require modifications like a lift kit to prevent rubbing at full turn.

Ground Clearance

The extra 1.07 inches of sidewall height gives the 285/70R17 1.08 more inches of ground clearance than the 265/65R17.

This added clearance aids off-road driving by reducing scrapes over obstacles. However, it also causes a lower speedometer reading for the 285/70R17.

Gas Mileage

The 265/65R17’s smaller size means less rotational mass and rolling resistance, contributing to better fuel efficiency crucial for daily driving. The larger 285/70R17 is less efficient due to more weight and drag.

Ride Comfort

The 265/65R17’s shorter sidewall transmits more road impacts into the cabin. The 285/70R17’s extra cushioning absorbs bumps better, although both sizes deliver a comfortable ride. The 285/70R17 also absorbs off-road impacts better.


Visually, the difference is subtle. The 285/70R17 appears slightly “stretched” due to the taller sidewall, suiting the look of trucks and SUVs. The 265/65R17 has a lower-profile appearance.

Handling & Stability

The 265/65R17’s shorter sidewall enhances responsiveness and handling precision on the pavement.

The taller 285/70R17 sidewall flexes more, reducing handling sharpness slightly. Both offer stability, but the 265/65R17 is more agile on-road.

Noise & Vibration

The stiffer 265/65R17 sidewall transmits more road noise and vibration into the cabin. The 285/70R17’s additional flex dampens vibrations, providing a quieter ride. However, the differences are minor.

Durability & Wear

The 265/65R17’s size could allow more even treadwear and longer life. The heavier 285/70R17 puts more stress on components. However, both tires exhibit good durability.

Adverse Conditions

Both tires perform well overall in rain, snow, and off-road conditions. The taller 285/70R17 has a slight advantage off-road from the extra clearance, while the 265/65R17 is a bit more responsive on slippery surfaces.

Speedometer Difference

At the same actual speed, the 265/65R17 displays a lower speedometer reading than the 285/70R17.

For example, at 20 mph actual speed, the 265/65R17 speedometer would read around 18.7 mph. The smaller diameter 265/65R17 tire rotates more times per mile traveled.

What Does 265 65r17 Tire Mean?

The 265 65r17 tire size is a standard option for light trucks and SUVs. This size represents the width of the tire in millimeters (265), the aspect ratio (65), and the diameter of the wheel in inches (17).

The “R” in this size represents the type of tire, which, in this case, is a radial tire. The width of a tire is important because it affects traction, handling, and fuel economy.

Our Observation
The 275/65R18 and 295/70R18 exhibit minor differences, making each better suited for particular needs. The 275/65R18’s shorter sidewall enhances responsiveness and handling for on-road driving.

Meanwhile, the taller 295/70R18 provides greater comfort and capability for off-road use due to added ground clearance and cushioning.

While both perform well overall, the 295/70R18’s advantages in absorbing impacts, smoothing bumps, and clearing obstacles make it better for rugged terrain and SUVs.

For responsive daily driving, the 275/65R18 is ideal. But for moderate off-roading, the 295/70R18 is recommended to maximize capability and comfort.
