Difference Between 255 and 265 Tires – Which One Will Give You a Smoother Ride?

difference between 255 and 265 tires

Whether 255 or 265, the size of tires you are using on your car matter. However, many of us give little thought to the size of tires that we use on our cars.

Tires come in different sizes. Although you can use different sizes of tires on your vehicle, this can be costly and sometimes dangerous. We must understand the sizes and their meaning before choosing which tires we can put on our car.

Some of us are more interested in small and others in bigger size tires. But, have you ever asked yourself which size is better for your vehicle?

Which tires for which vehicle?

Most popular car tires

The size of wheels you pick for your vehicles should always be the best fit. It is to give the best contact of your car to the ground. As someone would tell you, the best the grip your tires have with the ground, the more stability your vehicle has on the road.

Bigger wheels equal bigger cars. The larger the rim of your car, the larger the size of tire your car can use. However, for most light pickups, SUVs, and passenger cars weighing ½ ton and below, the tires are marked as either p-Metric or Euro-Metric. As said before, both metrics are suitable for any passenger vehicle, including personal cars, SUVs, minivans, and light pickups.

If your vehicle does not fall under these two metrics, especially vans and larger pickups weighing up to ¾ tons, two categories are common; “LT” and “ST” metrics. LT-metrics is meant for light trucks, while ST-metrics is meant for special trailers.

Regardless of which type of metric you are using, a size chart can help find the tire size best fits your vehicle.

Different tire sizes

Different sizes of tires are meant to fit different types of cars. There are many sizes, from small to larger sizes. However, the most popular tire sizes are 33 inches, 35 inches, 37 inches, 255/45R20, 265/45R20, 275/70R18, and 285/70R17.

These are well noted on the sidewalls. Each tire numbers and letters denote the width, height of the sidewall ratio, and the diameter of the wheel.

Features and specifications of 255 tires

The 255 tires are meant to withstand more load. Its features and specifications include:

  • Load range: H
  • Rim Width: 7.5 inches
  • Diameter: 36.7 inches
  • Thread depth: 18
  • Speed rating: 81 mp/h
  • Revs per mile: 566
  • Single maximum load: 2,500 Kilograms

Features and specifications of 265 tires

  • Load range: G
  • Rim width: 7.5 inches
  • Diameter: 38.9 inches
  • Thread depth: 20
  • Speed rating: 75 miles per hour
  • Revs per miles: 534

Differences between 255 and 265 tires

There are notable differences between these two tire sizes. Key among these are weight, gas mileage, the number of car loads each can sustain, stability, and maneuverability. However, there is little difference in their width. At the same time, their diameter sizes are different.

#1. Weight

The weight of 255 tire size is 42.722 kilograms. On the other hand, 265 size measures slightly higher, reaching a maximum weight of 45.891 kilograms.

The weight of each tile is important when choosing which type best fits your car. Although one changes the rims of 255 to fit 265 in their vehicle, subsequent change of weight of the tires can affect the speed and overall road performance of your vehicle.

You mean that using a 265 tire will make your car heavier, slowing down its speed. If your car is lighter but still has options to choose which one to use, go for the lighter one if you are looking for speed.

#2. Overall gas mileage

The heavier the tires, the more fuel they will consume. Therefore, the amount of gas required by your vehicle while using a 265 size is higher than 255 sizes.

To make sense of this, we look at the tread size of the two. The thread depth of 255 is 18, compared to 20 for a 265 size. Vehicles using 265 sizes require more effort compared to 255 sizes. The effort will then translate to more fuel consumption.

Using 255 sizes is more economical in terms of fuel consumption than 265 sizes.

#3. Amount of load endured

The maximum amount of load that a single 255 tire can sustain is 2,500 kilograms. It compares to the 2,360 kilograms that a single 265 tire size can hold. It means that 255 tire sizes can endure more weight compared to 265 tire sizes.

Therefore, it is important to consider what you want to do with the vehicle and the right amount of load you will be carrying while choosing between the two. For heavier loads, you can go for size 255, while 265 can still sustain a considerable amount of weight, though lower than 255.

To understand the amount each size can endure, look for information given by the load index on the sidewall of each tire.

#4. Stability

The stability of your vehicle is very important while you are running on the road. The larger the tires are, the more stable your car will be. It is also crucial for fast drivers or when driving on rough roads. Wider tires will give you that extra stability and keep you out of danger.

With an extra 10 mm width, 265 is wider and can provide you with the required stability. Although a 10 mm difference might seem small on the eyes, it makes a huge difference when giving your desired stability when speeding.

#5. Maneuverability

The size of your tires is critical for the grip your car has on the road. An increase in tire width ensures that you cover more surface area. It also gives your car a higher amount of hold to the ground, increasing your capability to maneuver.

Therefore, in our case, 265 tire size is considerably bigger than 255 tire, which automatically tells us that it gives more opportunity for the driver to maneuver. Therefore, if you like trying new things on the road, you would probably go for 265 tire size.
