235 vs 285 Tires

The main difference between a 235 tire and a 285 tire is the width – a 285 tire is 50mm (or about 2 inches) wider than a 235 tire.

This translates to a 21% increase in tread width for the larger 285 tires. The wider tread provides more contact with the road surface.

Ground Clearance

The larger 285 tire will provide slightly more ground clearance due to its taller sidewall.

This extra clearance can help prevent scraping or damaging the undercarriage on rough roads or off-road conditions. However, the lower profile 235 tire will result in a slightly higher speedometer reading.

Gas Mileage

The 235 tire’s smaller contact patch and lower rotational mass give it a fuel efficiency advantage over the wider 285.

With today’s focus on improving gas mileage, the 235 is the better choice for daily commuting and long highway drives. The minimal difference in efficiency will add up over thousands of miles.

Ride Comfort

While the 285 offers a smoother ride off-road, the 235 provides a more comfortable experience on paved roads.

The lower profile 235 absorbs less impact but transmits fewer vibrations on smooth highways and city streets. For an all-around comfortable ride, the 235 is the way to go.


The wider 285 tire provides a more aggressive, rugged look, especially on trucks and SUVs. However, the narrower 235 contributes to a vehicle’s aerodynamic efficiency.

For aesthetics alone, personal taste will determine whether the 285’s wider footprint or the 235’s aerodynamic styling is more appealing.

Handling & Stability

The 235 tire delivers quicker steering response and enhanced handling on pavement compared to the wider 285.

The 285 provides improved traction and stability in off-road conditions thanks to its larger contact patch. For responsive daily driving, the 235 is ideal, but the 285 offers an advantage in mud or uneven terrain.

Noise & Vibration

While the narrower 235 transmits more road irregularity vibrations, it provides a quieter ride on smooth roads.

The large air volume and added sidewall of the 285 help absorb vibrations but generate more noise due to the tread. Overall, the difference in noise and vibration between the two tire sizes is minimal.

Durability & Wear

The lower profile 235 tire often exhibits more even treadwear and a bit longer life than the larger 285.

However, the wider 285 is built to withstand more impacts and absorb more stress from potholes or off-road conditions. For the most extended tread life with normal driving, the 235 has a slight durability advantage.

Adverse Conditions

In snowy or icy conditions, the thinner 235 can cut through to the road surface better than the wider 285.

But for specific muddy or rugged off-road situations, the 285’s added traction provides an advantage thanks to its larger contact patch. On balance, the difference in snow or mud traction between the two tire sizes is small.


Due to its slightly larger overall diameter, the 285 tire will register a slightly lower speedometer reading than the 235 at any given speed.

This difference is minimal but worth considering if accurate speed is vital. Overall, either tire size should maintain a speedometer accuracy within acceptable limits.

How Much Taller Is A 285 Tire Than A 235?

The tire’s height depends on its width, aspect ratio, and rim size. If we consider the aspect ratio and rim size to be constant for both tires, we can determine the height difference based on their widths.

Let’s assume both tires have a 70 aspect ratio, meaning their height is 70% of its width. A 235 tire would have an approximate overall diameter of 735.4 millimeters. In comparison, a 285 tire would have an overall diameter of around 805.4 millimeters. Consequently, the 285 tires would be roughly 70 millimeters taller than the 235 tires.

Are 235 And 285 Tires Interchangeable?

If there is an overlap in the rim width specifications for both 235 and 285 tires, it is feasible to substitute 235 tires with 285 tires, provided that the vehicle’s rims are within the suggested range for the 285 tire size.

The advised rim width for the 235 tire size spans 6.5 to 8.5 inches, while the 285 tire size’s range is 8.5 to 10.5 inches. Given the overlapping ranges, 235 and 285 tires are interchangeable based on rim width.

How Much Wider Is A 285 Tire Than A 235?

The 285 tire is significantly wider than a 235 tire, with a difference of 1.97 inches (50 millimeters), equating to a 21.3% increase in width.

This notable variance highlights the 285’s broader tread, which enhances its contact with the road for improved traction and stability.

Our Observation
After reviewing the comparisons between 235 and 285 tire widths, I feel the 285 is better suited for my needs. The marginally reduced gas mileage is a worthwhile trade-off for the improved stability, traction, ground clearance, and aesthetics the wider tires provide.

As an avid off-road enthusiast, I frequently navigate uneven terrain and value the subtle comfort and control advantages of the 285. While the 235 may exhibit slightly better wear and efficiency, I prioritize capability over longevity.

For my purposes, the wider stance and tread make the 285 the superior choice. The minor downsides in handling and road noise are acceptable to me. Based on my priorities, I prefer the 285 over the 235 for both styling and performance.
