235 vs 245 vs 255 Tires: Can They Be Interchangeable?

Choosing the right tire for your vehicle is crucial to ensure optimal performance and safety on the road. with so many tire options available, it can be overwhelming to determine which one is suitable for your car. One common dilemma among car owners is whether tires with slightly different sizes can be interchangeable. There has been a debate on whether 235 vs 245 vs 255 tires can be swapped out without any issues.

In this article, we will explore the differences between these three tire sizes and examine whether they can be used interchangeably. We will discuss how these variations affect your vehicle’s handling, fuel economy, and overall performance.

What Do 235, 245, And 255 Tires Mean?

When it comes to buying tires for your vehicle, you might notice numbers like 235, 245, and 255 listed on the tire sidewall. These numbers are not just random digits but actually denote the width of the tire in millimeters. A tire with a width of 235 means that it is 235 millimeters wide from one sidewall to another.

The second number (245 or 255) represents the aspect ratio of the tire. This number tells you about the height of the sidewall relative to its width. For instance, if you see a tire size of P245/50R17 on your vehicle’s tire sidewall, it indicates that the aspect ratio is 50%, which suggests that this particular model has a sidewall height equivalent to half its width – i.e., (0.5 x 245mm).

235 vs. 245 vs. 255 Tires: What Are The Differences?

235 vs 245 vs 255 Tires

Tire Width

The width of a tire can have a significant impact on your car’s performance and handling, as well as its appearance. Choosing between different tire widths can be confusing, especially if you don’t understand the differences between them.
The three most common tire widths are 235, 245, and 255. For starters 235mm tire is narrower than 245mm and 255 mm tires but wider than 225mm and 215mm tires. These numbers refer to the width of the tire in millimeters from sidewall to sidewall when mounted on a standard rim size. While these three sizes may seem very similar at first glance, there are some key differences that can affect how they perform on the road.

Minimum Rim Width7.5 inches8.0 inches8.5 inches
Maximum Rim Width9.0 inches9.5 inches10.0 inches
Ideal Rim Width8.0 – 8.5 inches8.5 – 9.0 inches9.0 – 9.5 inches

Rolling Resistance

One major difference between these tire sizes is their rolling resistance. Rolling resistance refers to the amount of energy required to keep a tire moving forward at a constant speed. A narrower tire like a 235 will generally have less rolling resistance than a wider tire like a 255 because there is less rubber in contact with the road surface. This can result in better fuel efficiency and lower emissions for cars with smaller engines or hybrid powertrains that prioritize efficiency over performance.


Bigger tires will carry more loads than smaller ones because of their respective designs.The 255 is designed to carry the heaviest of loads followed by the 245 and lastly, the 235. It means that 235 has the least load carrying capacity among these three tire sizes.

Braking Distance

The main difference between these three sizes is their width. A tire with a width of 235mm is narrower than one with a 245mm or 255mm. This means that a narrower tire will have less contact with the road surface than a wider one. This doesn’t necessarily mean it will have worse braking performance. Narrower tires can provide better braking distance in wet conditions because they allow water to be displaced more efficiently from the road surface.


Wider tires provide better grip and handling because they have more contact with the road surface. Wider tires also create more drag and can reduce fuel efficiency. 255mm tire will have better grip comapred to 245mm and 235mm tire.


The first factor to consider when comparing these three tire sizes is their width. A 235 tire is narrower than a 245 or a 255 tire. The wider tires provide a better grip on the road surface and improve handling performance compared to the narrower ones. Wider tires also have more rolling resistance, which can lead to decreased fuel economy.


The 255 tires are the priciest while the 245 tires fall in between the cost of the 255 and 235 tires. This is reasonable as constructing a larger tire requires more resources.

Are 235 And 245 Tires Interchangeable?

The answer is yes, they are interchangeable under certain conditions.
Both tire sizes have similar diameters, with a difference of only about half an inch. This means that in most cases, you can use either size without any problems. It’s important to note that the two sizes may have different load ratings and speed ratings. Before swapping out one size for another, be sure to check these ratings on both sets of tires to make sure they’re compatible with your vehicle.

Can I Replace 235 Tires With 245?

You may wonder if you can replace your current 235 tires with a slightly larger size, such as 245. The good news is that it is possible to replace 235 tires with 245 without causing any major issues.

Are 245 And 255 Tires Interchangeable?

245 and 255 tires are often used interchangeably in cars, trucks, and SUVs. The main difference between the two tire sizes is the tire’s width. A 245 tire has a width of about 9.6 inches, while a 255 tire has a width of about 10 inches. This slight variation in size does not affect their compatibility with different vehicles.

Can I Use 255 Tires Instead of 245?

If you’re looking to change your car’s tire size, it’s common to wonder if you can use a larger size than what came with your vehicle. Often, people ask if they can use 255 tires instead of the standard 245 tires. The good news is that, in most cases, you can.
There are a few things to consider before making the switch. First, you must ensure the larger tire will fit on your vehicle without causing any issues. This includes checking clearance for the tire’s diameter and width and for rubbing or interference with other components.

Can I Replace 255 Tires With 245?

The answer is yes if you’re wondering whether you can replace your 255 tires with 245. While it may seem like a significant difference in size, replacing one tire size with another is quite common.


The answer to “235 vs 245 vs 255 Tires: Can They Be Interchangeable?” is yes. While slight differences in performance and fitment may exist, somebody can still use these tires on the same vehicle without causing any major issues. It is important to consider factors such as load capacity and speed rating when selecting a tire size, but ultimately it comes down to personal preference and what works best for your driving needs. With proper maintenance and regular checks, any of these tire sizes can provide a safe and reliable driving experience. So next time you need new tires, don’t hesitate to explore all three options and choose the one that suits you best.


Can I put 2 different size tires on my car?

Yes, you can put different size tires on your car. The diameter of the tire must be within the manufacturer’s recommended range for your car.
