295/70r17 vs 285/70r17

The main difference between 295/70r17 and 285/70r17 tires is in the section width. The 295/70r17 tire size is about 0.39 inch wider than the 285/70r17 tire size.

This width difference impacts various performance factors like handling, fuel efficiency, noise levels, and off-road capability.

295/70r17 vs 285/70r17

Fitment Guide

The 295/70r17 diameter is 1.7% larger than the 285/70r17, so both sizes could potentially replace one another without modifications. However, the wider 295 may still rub at full lock in some vehicles.

Gas Mileage

The thinner 285/70r17 tire has marginally less rolling resistance from its smaller contact patch, making it slightly more fuel-efficient.

Over long distances, this could amount to measurable fuel savings. However, the difference is generally relatively small between these sizes.

Ground Clearance

With a 1.7% larger overall diameter, the 295/70r17 offers 0.28 inch more ground clearance than the 285/70r17 size.

This modest increase can help prevent scrapes over rough terrain. But it also causes a 1.7% lower speedometer reading.

Ride Comfort

The extra cushioning from the 295/70r17’s additional sidewall height absorbs more road impacts, potentially providing a smoother ride over uneven surfaces. But both deliver comfortable on and off-road performance.


Visually, the difference between these sizes is subtle. The 295/70r17 will have a slightly taller sidewall, giving it a vaguely “stretched” look. This appearance suits trucks and SUVs well but is ultimately just a minor variation.

Handling & Stability

The shorter sidewall of the 285/70r17 affords slightly crisper responsiveness and handling over the 295/70r17.

But the 295 offers somewhat better stability off-road from its extra sidewall flex. Either way, the differences here are modest at most.

Noise & Vibration

With more sidewall cushioning, the 295/70r17 dampens vibrations better, transmitting less road noise into the cabin. But expect only a minor reduction versus the 285/70r17 unless road conditions are very uneven.

Durability & Wear

The narrower 285/70r17 may potentially exhibit more even wear across its tread width as well as marginally longer tread life from lower rolling resistance. However, both sizes deliver plenty of mileage when appropriately maintained.

Adverse Conditions

Rain, snow, and off-road performance is comparable between these two sizes. The 0.28-inch increase in ground clearance gives the 295/70r17 a slight edge over obstacles, but the difference is small. Either can adeptly handle adverse conditions.

Speedometer Difference

At an actual speed of 20 mph, the speedometer reads 19.67 mph with 285/70r17 tires and 20.0 mph with 295/70r17s, owing to their 1.7% larger diameter. Expect a modest 0.33 mph speedometer discrepancy between these sizes.

Can I Replace 285/70r17 With 295/70r17?

Yes, you can replace 285/70R17 tires with 295/70R17 tires. The diameter difference between these two tire sizes is only 1.7%, which is less than the 3% difference typically recommended as the maximum when replacing tires.

With only a 1.7% difference in diameter, there should be negligible effects on gearing, speedometer/odometer accuracy, and vehicle handling when going from the smaller to the slightly larger tire size.

What Does 285/70r17 Mean?

The 285/70R17 tire size is equivalent to 32.8×11.2R17 in inches. The tire size 285/70R17 is widely used on many trucks, SUVs, and other larger vehicles. This tire size has the following dimensions and components:

  • 285: This number indicates the tire’s width in millimeters, which is 285 mm for this tire size.
  • 70: This number indicates the tire’s aspect ratio, which is the height of the tire’s sidewall as a percentage of its width. In this case, the sidewall height is 70% of the tire’s width.
  • R: This letter stands for radial construction, the most common tire construction type nowadays.
  • 17: This number represents the diameter of the wheel that the tire is designed to fit on in inches. Specifically, this tire size is designed to fit on a 17-inch wheel.

What Does 295/70r17 Mean?

The tire size 295/70r17 is equivalent to 33.3×11.6R17 in inches. The notation “295/70R17” refers to the size of a tire. Here’s a breakdown of what each part of the notation represents:

  • 295: This number represents the width of the tire in millimeters. In this case, the tire is 295 millimeters wide.
  • 70: This number is the aspect ratio, the ratio of the tire’s height to its width. In this example, the height is 70% of the tire’s width.
  • R: This letter indicates that the tire has a radial construction. Most modern tires use radial construction.
  • 17: This number represents the diameter of the wheel (rim) in inches. In this case, the tire is designed to fit a 17-inch wheel.

So, a tire with the size 295/70R17 is 295 millimeters wide, has an aspect ratio of 70%, features radial construction, and is designed to fit a 17-inch wheel.

Our Observation
Regarding the 295/70r17 and 285/70r17 tire sizes, differences in performance are generally minor. The 295/70r17 offers slightly better ride quality and off-road capability from its increased diameter and sidewall height.
