What is the Difference Between 255 and 265 Tires?

The core difference between 255 and 265 tires comes down to width:

  • A 255 tire measures 255 millimeters across
  • A 265 tire is 265 millimeters wide

So a 265 tire is 10 millimeters or about 0.4 inches wider than a 255 tire. This seemingly small difference has implications for performance, handling, wheel fitment, and visual appeal.

Along with width, we need to consider other tire size measurements:

Tire Size Metrics

Tire sizes follow a standard format:

  • Tire Width / Aspect Ratio R Wheel Diameter
  • Tire Width - The width in millimeters. This is the 255 vs. 265 distinction.
  • Aspect Ratio - Sidewall height as a percentage of width. Affects overall diameter.
  • R - Indicates radial construction, the most common modern type.
  • Wheel Diameter - The diameter of the wheel the tire fits in inches.

For example, a 255/55R18 tire would have:

  • 255mm width
  • 55% aspect ratio
  • 18-inch wheel diameter

With the key tire size metrics covered, let's compare 255 vs. 265 tires in detail.

Overview of Differences

Given the same aspect ratio and wheel diameter, the key distinctions between 255 vs. 265 tires are:

  • Tire Width - 265 is 10mm (0.4 inches) wider
  • Diameter - 265 is slightly taller due to wider width
  • Circumference - 265 has a larger circumference
  • Revolutions Per Mile - 265 has fewer revolutions per mile
  • Rolling Resistance - 265 has a higher rolling resistance
  • Weight - 265 weighs more
  • Load Capacity - 265 typically has a higher load capacity
  • Dry Traction - 265 has better traction and grip
  • Fuel Economy - 255 is slightly more efficient
  • Price - 265 costs more

These differences influence everything from ride quality to fuel usage. Let's explore further how tire width impacts performance.

How Tire Width Affects Handling, Grip, and Performance

That extra 0.4 inches of width might not seem like much. But even a 10mm difference between 255 vs. 265 tires has a measurable impact.

Vehicle Handling and Grip

One key advantage of 265 over 255 tires is improved handling and grip:

  • More traction - The wider 265 contact patch enables more traction, increasing acceleration, braking, and cornering capabilities.
  • Better handling - The 265 provides sharper, more responsive steering input and handling balance.
  • Increased stability - Added rubber on the road enhances stability at high speeds.
  • Improved cornering - Extra sidewall stiffness from the wider tire resists body roll.

Essentially, the 265 approaches performance tire levels of grip and handling compared to a 255 tire. This makes the 265 popular for trucks, SUVs, and sports cars where drivers want to amplify cornering power and road holding.

Traction in Different Conditions

Along with vehicle handling, a 255 vs. 265 tire's traction varies by conditions:

  • Dry traction - The 265 dominates with its larger contact patch and sticky rubber compound.
  • Wet traction - 265 tread patterns efficiently displace water for solid wet traction.
  • Snow and ice - Surprisingly, the narrower 255 fares better, with its higher pressure per inch piercing through the snow to the pavement.

So while the 265 excels in the dry, the 255 has merits in slippery conditions. Tread design plays a role as well.

Impact on Rolling Resistance and Fuel Economy

The 265's extra width also comes with a downside of decreased fuel efficiency:

  • More friction - The larger contact area creates more rolling resistance, requiring extra energy to roll.
  • Added weight - More material results in increased tire weight which affects efficiency.
  • Aerodynamics - The bigger profile leads to slightly more air resistance at highway speeds.

Consequently, you can expect 1-3% worse fuel economy when moving from 255 to 265 tires based on vehicle and conditions.

Load Capacity

Load capacity is a crucial specification to consider with wider tires.

  • The 255 tire provides around a 2,400-pound load capacity.
  • The 265 increases this capacity to approximately 2,680 pounds.

So for regular heavy hauling or towing, the superior durability and load handling of the 265 make it the better choice.

Speed Rating

We also need to factor in speed rating when comparing 255 vs. 265 tires:

  • The 255 will typically have an H speed rating, meaning it can safely handle speeds up to 130 mph.
  • Many 265 tires boast a higher V rating, increasing maximum speed to 149 mph.

This makes the 265 ideal for performance vehicles that cruise at higher speeds.

Wheel Fitment

An important criterion is whether your existing wheels can fit the new 255 or 265 tires.

Rim Width

  • 255 tires require rims between 7 and 9 inches wide.
  • 265 tires fit rims ranging from 7.5 to 9.5 inches wide.

So there is a nice overlap in terms of recommended rim widths. In most cases, a rim that fits a 255 will also work with a 265 and vice versa.

Just verify your wheels fall within the width range for the desired tire size. Too narrow or wide of a rim can cause fitment and handling problems.

Rim Diameter

The wheel diameter must match the new tire size. For example, both 255/55R18 and 265/50R18 tires mount on 18-inch rims.

As long as the rim diameter is compatible, switching between 255 and 265 widths is straightforward provided the rim width can accommodate the new tire size.


Along with performance impact, tire width also influences aesthetics. Personal preference plays a role:

  • Some feel the 265's added girth conveys a more aggressive, muscular look.
  • Others like the 255's narrow proportions for a lighter, nimbler vibe.
  • Larger diameter wheels can amplify the visual difference between widths.

Choose the tire size that aligns with your desired style. Both widths can look great depending on preferences.


Expect to pay a small premium for 265-width tires compared to 255s:

  • More material - The wider 265 requires more rubber and materials, elevating manufacturing costs.
  • High demand - 265 tires are popular for trucks and performance cars, sustaining higher prices.
  • Low supply - Producing wider tires necessitates specialty molds, restricting manufacturing volume.

Plan for $25-50 more per 265 tires compared to a 255. Actual pricing depends on specific tire models and brands.

Pros and Cons of 255 vs 265 Tires

Let's summarize the unique advantages of each width:

255 Tire Benefits:

  • Better fuel efficiency
  • Improved snow and ice traction
  • Lower cost
  • Lighter weight
  • Smoother, quieter ride quality

265 Tire Benefits:

  • Increased dry traction and grip
  • Sharper handling and cornering response
  • Added durability and longevity
  • Higher load capacity
  • The visual appeal of a wider stance

With these pros and cons defined, you can determine which width best fits your priorities.

Ideal Vehicles for 255 vs 265 Tires

Given the performance differences, 255 and 265 tires are better suited for certain vehicles and applications.

Best Applications for 255 Tires

The 255 tire's superior fuel efficiency makes it ideal for:

  • Passenger cars
  • Crossover SUVs
  • Small/midsize SUVs
  • Light duty pickup trucks focused on street usage

Essentially, the 255 fits best on lighter vehicles prioritizing efficiency and ride comfort over maximum trailering or hauling needs.

Best Applications for 265 Tires

With its load capacity and performance advantages, the 265 excels on:

  • Full-size SUVs
  • Heavy-duty pickup trucks
  • Commercial trucks
  • Performance cars and trucks
  • Off-road vehicles
  • Race cars

So the 265 is preferable for larger, heavier vehicles or those requiring amplified grip, handling, and stability.

Interchangeability of 255 and 265 Tires

A common question is whether you can swap between 255 and 265 tires on the same vehicle. In most cases, the answer is yes:

  • As outlined earlier, rim width compatibility ranges overlap nicely between the two sizes.
  • The minor diameter difference won't introduce fitment issues.
  • Just ensure your wheels match the diameter of the new tires.

However, mixing widths on the same axle is problematic. The slight diameter variance forces each tire to turn at different speeds.

So it's essential to replace all four tires when switching from 255 to 265 or vice versa. Never pair different widths on the front or rear.

Here are some tips for successfully interchanging 255 and 265 tires:

  • Transition to the new size as a set of 4 when your tires need replacement.
  • Adjust tire pressures to account for the width change and restore proper handling balance.
  • Get a wheel alignment to correct minor geometry changes.
  • Reset the TPMS if your vehicle has tire pressure monitors.
  • Recalibrate the speedometer to reflect diameter differences. Many vehicles do this automatically but verifying prevents false speedometer readings.

Provided you take these precautions, changing between 255 and 265 widths is straightforward in most cases.

Real World 255 vs 265 Tire Examples

Let's compare some popular real-world examples of 255 and 265 tire sizes:

255/70R15 vs 265/70R15 Tires

For a common 15-inch rim diameter:

  • The 255 tire is 31.1 inches tall with a 10-inch section width.
  • The 265 measures 31.6 inches tall and is 10.4 inches wide.

So the 265 is 0.5 inches taller and 0.4 inches wider than the equivalent 255 tire.

255/75R17 vs 265/70R17 Tires

Looking at two prevalent truck sizes:

  • The 255 comes in at 31.1 inches overall diameter with a 10-inch width.
  • The 265 is slightly shorter at 30.7 inches in diameter but wider at 10.4 inches across.

Here the 255 actually has marginally more sidewall height. But most favor the 265's broader traction and handling over minimal diameter gain.

255/55ZR18 vs 265/50ZR18 Tires

For a performance vehicle wheel diameter:

  • The 255 measures 26.1 inches tall with 10 inches of width.
  • The 265 is larger in diameter at 27.1 inches yet wider at 10.6 inches across.

So for low-profile performance tires, stepping up to a 265 allows running an even lower profile while maintaining overall diameter. This amplifies grip without introducing fitment problems.
