255 Vs 265 Tires: Must Follow This Guide Before Buying Them

Tires are vital parts of your vehicle and its operation. If you do not get the same tires when you buy new ones, there may arise several critical issues. Like, when you are confused to buy tires like 255 or 265 then you must know the major difference between them.

According to a detailed comparison, the main difference between 255 vs 265 tires is in the circumference, and the revolution of these two comparative diameters is 1.4 percent. There is also a 3.9 percent discrepancy in these two measurements’ widths.

To learn more about tire differences with all other additional information, continue to read this article.

The Main Comparison Between 255 Vs 265 Tires:

Three sets of numbers are often used to characterize a tire. For example, 255/60r17. The first is the breadth, the second is the aspect ratio, and the third is the object’s diameter.

The difference between them is in their overall size. The 255 tire is slightly smaller than the 265 tires. Plus, the difference will be in the actual speed of the car. No matter the rim size, 16 or 17, the speed difference is 1.25 mph over what the speedometer reads.

Finally, there is a 3% fluctuation in sidewall inches. It must be a lot of labor with so many numbers. Following your handbook can be the salvation since it already lists the size of the tires you are intended to seek.

Even if that isn’t enough, we can always look at what other people have to say about the product in the form of testimonials. As you can see, the 255s are a little higher than the 265s in height.

There is a slight difference in width between the 265 and 255 models. People, on average, prefer 255s over 265s when it comes to service and comfort.

255 Or 265 Tires: What’s The Core Difference?

Let’s talk about the performance implications of 255 vs 265 tires differences! Because the two tire sizes are so similar, the automobile’s overall performance isn’t adversely affected. Is there a difference between the two?


More stability is possible with larger tires. This is especially important while traveling at high speeds since a more stable vehicle implies a safer ride. Additionally, a more stable tire provides superior braking power, essential while driving at high speeds or on rough roads.

Between 255 and 265 tires, there isn’t much of a difference in stability. However, if you wish to drive quickly and require more strength, you might use 265-size tires.

Fuel Mileage:

As previously stated, heavier tires use more gasoline. Only 1-2 miles will be lost when you change from 255 to 265 tires. This is because the tread sizes of these two tires are pretty similar.

Because heavier tires demand more effort to operate, they impair fuel efficiency. It burns more gasoline and has a worse gas economy because of its increased resistance.

Thinner, lighter, and lower rolling resistance tires are common in cars with low fuel consumption. Because of this, the vehicle can go further on less gasoline.

You can save money by purchasing 255-series tires, but you won’t sacrifice mileage.

Loading Capacity:

When loaded to their total capacity, 255 tires can support a weight of 900 kilograms (1980 pounds), while 265 tires can handle weight as high as 1050 kilograms (2300 lbs). To guarantee that you don’t place light tires on a large vehicle, it is important to declare this weight.

Your vehicle’s weight is a factor to consider when selecting the correct tire size for your car. Otherwise, the results might be disastrous.

The load index, which is included in the tire’s unique code, provides this data.

Tires’ Gross Weight:

255 tires weigh roughly 36 pounds, but 265 tires weigh approximately 53 pounds. 255 tires weigh 17 pounds less than 265 tires.

However, using heavy tires necessitates a larger, more powerful vehicle. The heavier the tires, the more excellent the car’s traction and performance on the road. Heavier tires may slow the acceleration of lighter vehicles.

Fuel consumption rises due to the additional weight of large tires on a large vehicle. As a result, thicker tires may not be the most cost-effective option for your vehicle.

Speed And Agility:

Larger tires provide improved mobility by covering a larger area of the road. Your vehicle’s handling improves as it travels across a significant region of the road.

Theoretically, a car with 255 tires may have worse handling than a vehicle with 265 tires.

Understanding The Measurement Of A Tire Size

Once you’re familiar with the terminology, it’s simple to decipher the various components of a tire size measurement. Now that you understand the meaning of each tire size component, we can demonstrate how to read a tire size from its sidewall.

An example of a P265/50R18 103H tire is as follows:

Tire Type-P: Passenger tires, like this one, are pretty prevalent.

“Tire Width” 265 From sidewall to sidewall, the tire’s width is 265 millimeters (just over ten inches).

Aspect Ratio-50: The tire’s sidewall is 114 millimeters long, or slightly more than 4 inches wide since it accounts for half of the tire’s width.

Construction Type-R: The most prevalent tire manufactured today is the radial tire.

Wheel Size/Rim Diameter-18: The tire’s circumference, measured edge-to-edge, is 18 inches.

This tire has a load index of 103, which indicates it can carry 1,929 lbs.

Rating for Speed-H: A tire with a speed rating of “H” can withstand speeds of up to 130 mph.

To summarize, a P265/50R18 103H tire has a width of 265 millimeters, a thickness or aspect ratio of 45 percent of the tire height, and a height of 114 millimeters.

The 18-inch radially built tire has a load capacity of 1,929 pounds and a maximum speed of 130 miles per hour.

Why Tire Size Is Important?

Tires must be the proper size for several reasons besides that they must fit on your car. Your tires are the only pieces of your automobile that come into touch with the road, and they sustain the whole weight of your vehicle. When it’s time to buy new tires, choosing the correct size for your car and tires is vital.

Because the role of a tire is to transport and direct your vehicle where it needs to go, it is critical that the size of a tire be just right to ensure your vehicle’s safety. To spin and move your automobile, you’ll need tires that are broad, sturdy, and thick enough to handle the weight.

You may have to replace your tires sooner than you’d like if you damage them by scratching along the sides or getting trapped while attempting a turn.

Do 265 Tires Fit On a 255 Wheel?

Changing from 255 to 265 millimeters will raise the tire’s actual height by 14 millimeters. For 265’s width, you’ll need a 67AR to maintain the same tire height. 265 is a lot closer to it than 70.

You can get away with going up or down a size when it comes to tire width, but altering the tire’s height might lead to problems. Keep to 70. 265/70r17 is about half an inch shorter than the 255/75r17 when comparing the two tires.

That means you don’t need a replacement if you believe 265 is acceptable. At the same aspect ratio, a 265 wheel would have a slightly larger outer diameter than a 255 at the same aspect ratio, which means the sidewall would be more significant.

Before Choosing A 255 Or 265 Tire, Here Are Some Things You Must Know

Tires have a “load index” that tells you how much weight they can take when completely inflated. The greater the load index value, the greater the capacity of the tire to bear that weight. Tire load index rating charts show the relationship between the load index rating and the maximum weight that a particular tire can support.

An 81-load index indicates that the tire can carry 1,019 pounds. For example, It’s possible to have tires with a load index value of 150, which amounts to 7,385 pounds for the typical car.

Construction Types:

This has to do with the way the tire was put together. Since radial tires are the most prevalent type of tire manufactured today, you’ll often see the letter “R” for “radial tire.” Radial tires are created by building piles perpendicular to the direction they move, resulting in a smoother ride, longer tread life, and less fuel consumption.

Types of Tires:

The type of vehicle or function for which the tire was intended is the tire’s purpose. A passenger tire, denoted by the letter “P,” is the most prevalent. Another typical tire type name is “LT” (light vehicles that carry large loads). Another kind of tire is the “T” (temporary) tire, which may also be used on a trailer (commercial).

There is a good chance the tire was made in Europe for European automobiles if there is no letter. These tires are referred to as metric or Euro-metric tires, and they are pretty similar to a passenger tire in terms of design and function.

Ratio/Profile of Aspects:

Aspect ratio is the fraction of the tire’s sidewall height to the tire’s overall width. Measure the distance from the edge of the rim to the top of the tire at the edge of the tread to get the sidewall height.

Your vehicle’s ability to manage the tire depends on the tire’s aspect ratio. Low-aspect tires are frequently simpler to control because they react more quickly than high-aspect tires to steering commands.

Tire Length:

The width of your tire’s sidewalls measured from one end to the other in millimeters.

Rating of Speed:

Like the load index, the speed rating is another shorthand method of referring to the tire’s intended speed. When a tire’s top speed is shown, it’s denoted by a specific letter. For instance, a ” T ” speed rating indicates that the tire can speed up to 118 mph.

Size of Wheels/Diameter of Rims:

The diameter of your wheel is usually determined in inches by tracing the tire’s circumference from one end to the other. The diameter of the rim is commonly used as a shortcut for determining what size tire your vehicle requires.

The Advantages of Using Tires like 255 or 265

Here are some of the major advantages of using 255 or 265 tires. Continue reading:

Personalization and Aesthetics

Truck drivers are increasingly opting for larger tires, such as 265s, often paired with more giant rims and a higher suspension.

While some individuals like the off-road benefits larger tires provide, huge wheels may also be a fashion statement. It’s possible to personalize the appearance and feel of your vehicle by changing the size of your tires.

Assumed Warranty Can Be Voided

Even if you’re a fan of the look, certain car manufacturers will tell you not to go over 255 or 265 on your tires. If you opt to add bigger tires and a raise kit to your vehicle’s suspension, certain manufacturers may invalidate your warranty.

Improved Off-Road Capability

Some people feel that the better off-road handling provided by larger tires is due to the increased ground clearance. However, obtaining the correct size of all-terrain or max-traction tires for your truck or SUV may also improve its off-road performance.

Thanks to their more deep and broader treads, Max traction tires are strong enough to travel wherever the path takes you!

Enhanced Visibility

Larger tires like 265 provide more space between your car’s undercarriage and the ground, which is the most crucial advantage. Off-roading specialists, in particular, will like this feature since they need the additional room to navigate harsh terrain.

Do 265 Or 255 Tires Affect Mpg In Any Way?

Tires that are either 255 or 265 will impact your vehicle’s MPG (MPG). Several factors contribute to a decrease in fuel efficiency with bigger tires.

To begin with, 245/235-sized tires tend to be lighter than 255/265″ tires. Your car will gain a significant amount of weight if you install a set of four large and hefty tires. That extra weight might have a negative impact on your vehicle’s acceleration and fuel efficiency. As a result, slowing down the car will need extra effort from your brakes.

Secondly, bigger tires may protrude from the wheel well rather than lining up with your truck or SUV’s wheel well. Your car’s fuel efficiency will suffer as a result of this.

Because broader and more aggressive tires have a giant contact patch with the road, they might increase rolling resistance, as was previously discussed.

Do 255 or 265 Tires Affect The Speedometer?

Your speedometer’s accuracy will be impacted if you modify your vehicle with wider tires. This is because the circumference of your tires is used to calculate a portion of the speedometer’s readout.

If your speedometer isn’t adjusted for the larger circle of your new tires after you swap them out, it won’t show the right speed.

If your vehicle’s tire size has changed, you’ll need a technician to perform one of two things: either adjust the speedometer gear or reprogram the computer.

People Often Ask About 265 and 255 Tires

Can 255 tires fit 265?

Yes, it’s pretty probable. BUT! The wheel’s width determines whether or not a 255 mm tire will fit on your current 265 mm rims. One to two inches of rim width may be used for all tire sizes.

What is the size difference between 255 and 265 tires?

The 265 tire’s tread section width is 10 millimeters wider than the 255 tire’s tread section width. Adding and subtracting fractions is a piece of cake.

For example, 255/45/X16 is 255mm wide, the distance between the wheel and the circumference is 45percent of the width, and the diameter is 16in. Radial tires have three numbers on them.

Can I put a taller tire on my truck?

You certainly can. Changing to bigger tires is a simple process in most vehicles. Most trucks can accommodate tires up to 33″ without the requirement for a raise kit.

Some modifications such as tire spacers, leveling kits, adjusting torsional keys, and trimming offenders may be necessary, though.

How much bigger is a 265 tire than a 245?

There are ten millimeters difference between 245 and 265. Since so many things have changed, it’s only natural that the number 245 has been renamed to 265.

You may have heard that larger tires affect a car’s speed. However, this isn’t entirely true.

Can you replace 225 tires with 265?

In comparison to the 225, the 265 will be 40 mm broader. Make sure that the tire’s diameter is consistent throughout all of the various tire sizes by paying attention to this detail.

When you use this as computer input, you tell it how quickly you are moving.

265 70R16 vs. 265 75R16: What’s the difference?

The tire’s height or diameter increases from 265/70 to 265/75. The tire will be an inch higher as a result. A 265-millimeter-wide piece of stock is considered to be a standard size.

The speedometer will be slightly inaccurate because the taller tire does not spin at the same pace as the standard size.


This article has explained the difference between 255 vs 265 tires. Any option you make will be correct. If you’re looking to conserve some fuel, the 255 tires are an excellent choice.

However, if you want a smoother ride and more inside space, you may go for 265-sized tires instead of 255.
