7 Differences Between 245 Vs 275 Tires You Must Know

When choosing the right tires for your vehicle, size and specifications play a crucial role. Among the various options available, two popular choices are 245 vs 275 tires. These numbers might seem insignificant initially, but they are essential in determining your driving experience. Whether you are a car enthusiast or simply looking to upgrade your tires, understanding the differences between 245 and 275 tires is essential.

This article will delve into seven key distinctions that set these tire sizes apart. From their width to their performance capabilities, we will explore how each size impacts handling, traction, fuel efficiency, and overall ride quality.

What Do 245 and 275 Mean on Tires?

The first number (245) refers to the tire’s width in millimeters. This measurement represents the distance from one sidewall to another when the tire is mounted correctly on a specified rim width. In this case, a 245 tire would be approximately 245 millimeters wide from sidewall to sidewall.

275 represents another crucial aspect of a tire: its aspect ratio or profile. The aspect ratio signifies the relationship between the sidewall’s height and the tire’s width.

245 Vs 275 Tires

When choosing the right tires for your vehicle, size matters. Two popular options are 245 and 275 tires, but what sets them apart? In this article, we will explore seven key differences you must know before deciding.

245 vs 275 Tires Width Comparison:

The first thing to note is that these numbers represent the tire’s width in millimeters. So, a 245 tire would be narrower than a 275 one. This distinction may seem small, but it can significantly impact your driving experience.

245 vs 275 Tires Size:

A 245 tire has a width of 245 millimeters, while a 275 tire is more comprehensive with a width of 275 millimeters. The extra width on the latter provides better traction and stability when driving at higher speeds or taking sharp turns. Wider tires tend to have a larger contact patch with the road surface, improving grip and control.


The difference between a 245 and 275 tire may seem insignificant at first glance, but it can significantly impact various aspects of your driving experience. Let’s talk about the weight difference between the two sizes. A 245 tire typically weighs around 25-30 pounds, while a 275 tire can weigh anywhere from 30-35 pounds.


A narrower 245 tire offers several advantages over its more comprehensive counterpart. It tends to provide better traction on snow-covered or wet surfaces due to increased pressure exerted on the road. Narrow tires generally result in less rolling resistance, which can improve fuel efficiency by reducing engine effort.


A wider tire like the 275 offers enhanced grip and stability compared to its narrower counterpart, the 245. With more rubber in contact with the road surface, a wider tire improves traction during acceleration and cornering. This increased grip allows drivers to take turns at higher speeds without sacrificing control or compromising safety. A wider tire also provides better lateral stability, reducing body roll and improving handling performance.

Fuel Efficiency:

It’s crucial to note that tire width directly affects rolling resistance – the force required to move a tire forward. In general, narrower tires like 245 provide less rolling resistance than wider ones like 275. This means narrower tires need less energy from your engine, improving fuel efficiency. Narrow tires tend to have lower aerodynamic drag due to their smaller contact area with the road surface, contributing to better gas mileage.


The main reason why wider tires tend to provide better acceleration is due to increased traction. With more rubber in contact with the road, there is a greater grip available for launching off the line. This allows for quicker starts and reduced wheel spin, especially in high-powered vehicles. It’s worth noting that wider tires can also result in increased rolling resistance, which may slightly offset their advantage when it comes to acceleration.

Final Thoughts:

Understanding the differences between 245 vs 275 tires is essential for any car owner or enthusiast. From the size and width to the performance and handling, these factors can greatly impact your driving experience. While 245 tires offer better fuel efficiency and a smoother ride, 275 tires provide enhanced traction and stability on the road. It is crucial to consider the compatibility of these tire sizes with your vehicle’s specifications and suspension system. By knowing these distinctions, you can make an informed decision when choosing the right tire size for your car. So, take the time to research and consult with professionals before purchasing to ensure optimal performance and safety on the road.


What’s the difference between a 275 and a 255 tire?

The main difference between 275 vs 255 tires is their width. The numbers represent the tire’s section width, which is the measurement across the widest part of the tire when mounted on a specified rim width. In this case, a 275 tire is wider than a 255 tire.
