So, let’s compare 265/70R17 and 285/70R17 tires in terms of performance, fuel economy, ground clearance, control, grip, handling, and many more.

1. Fitment Guide

Fitment is essential for safety and performance.

When replacing tires, the difference between the new and stock tire’s diameters should be 3% to avoid speedometer inaccuracies and clearance issues.

The diameter of 285/70R17 is 3.5% bigger than the 265/70R17 tires.

This is slightly crossing the 3% limitation.

Therefore, the 265/70R17 fits most vehicles without any modifications.

But the 285/70R17 requires minor adjustments, just like trimming fender liners or installing spacers.

2. 265/70r17 vs 285/70r17 Gas Mileage

285/70R17 tire is wider than the 265/70R17 tire.

That’s why the rolling resistance of the 285/70R17 is higher than 265/70R17 tire.

Higher rolling resistance increases fuel consumption.

Therefore, the 265/70R17 tires provide better fuel efficiency than the 285/70R17 tires.

Some experiments show that both tires have nearly 1 mpg difference.

However, depending on the driving conditions, it may vary.

3. Clearance

The diameter of the 265/70R17 tire is 804 mm, while the diameter of the 285/70R17 is 832 mm.

The 285/70 R17 tire is 28 mm taller than the 265/70R17 tire.

That’s why the 285/70 R17 tire has 28 mm extra ground clearance, which provides better off-roading.

But 285/70 R17’s large diameter decreases the speedometer reading by 3.4% lower than the actual speed.

In contrast, 265/70 R17 provides correct speedometer readings.

4. Comfort

Tire size matters for better comfort and an enjoyable driving experience.

Tire sidewalls with larger heights absorb more roadside impact than those with lower heights.

This is especially noticeable on uneven surfaces.

The 285/70 R17 tire’s sidewall height is 200 mm and 265/70 R17 tire’s is 186 mm.

285/70 R17 extra 14 mm height provides a smoother and more comfortable ride in every condition.

5. Noise and Vibration

Sidewall height also affects vehicle interior noise and vibration.

A shorter sidewall means more noise and vibration than a taller sidewall.

In this equation, the interior of a vehicle with 265 70R17 tires is noisier than 285 70R17 tires.

But my personal experience says there is not much difference between 265 70R17 and 285 70R17 tires in terms of noise and vibration.

6. Controlling

Due to the shorter sidewall, the 265/70 R17 tires provide better control than the 285/70 R17 tires.

The 285/70 R17 tire’s extra sidewall slightly reduces the vehicle’s handling and response.

However, both tires are perfect for light off-road driving.

The 265/70 R17 tires provide better grip on packed snow, while the 285/70 R17 tires provide slightly more traction.

7. Outlook

Some owners only upgrade their vehicle’s tires for more aggressive looks.

The 285/70 R17 tires’ wider footprint and taller sidewalls give the vehicle a more aggressive look.

The tire also gives a better “off-road” look than the 265/70 R17 tire.
