Do you want to learn about the difference between 245 and 255 tires? Wanna know which tire size is the best for your vehicle?
Here, we will discuss the two tire sizes and guide you about their specifications. This way, you will end up making the right decision for your vehicle.
The main difference between a 245 and 255 tire is the width or, more specifically, the tread width. They both have different speed tolerance. So, let’s find out about all of them! That’s a basic overview, and there are a lot more differences.
What Kind of Tire Do I Need?
The determination of the right tire size not only depends upon the width but also on the aspect ratio, speed rating, rim diameter, etc. Tire sizes like the 245 and 255 are ideal for everyday use cars. These sizes are productive in medium carloads.
Tire sizes like 275 and 285 are for large trucks. SUVs can use a tire size of 215-235, depending upon their specificity.
Features of 245 Tires
Rim Width: 7.5 Inches
Load Range: G
Tread Depth: 19
Diameter: 37.4 Inches
Revs Per Mile: 555
Speed Rating: 81 miles per hour
245 tires are great for off-road driving as they are neither too small nor too large. 245 tires are constructed radially.
Features of 255 Tires
Rim Width: 7.5 Inches
Load Range: H
Tread Depth: 18
Diameter: 36.7 Inches
Revs Per Mile: 566
Speed Rating: 81 miles per hour
255 tires can handle more load than 245 tires and hence are better, but only if they are compatible. They also have R construction which makes them exemplary.
Difference Between 245 and 255 Tires
Let’s discuss the differences between 245 and 255 tires and how they can affect performance! These two tire sizes are close to each other; therefore, the differences don’t affect the car’s overall performance to a great extent. So, how do they differ?
| Features | 245 mm tires | 255 mm tires |
|---|---|---|
| Weight | 27 lbs | 47 lbs |
| Rim Size | 18 inches | 20 inches |
| Aspect Ratio | 45 | 55 |
| Load Capacity | 1764 lbs | 1819 lbs |
| Sidewall Height | 7.23 inches | 7.03 inches |
| Diameter | 30.47 inches | 30.06 inches |
| Speed Rating | T | V |
| Construction | Radical | Radical |
| Tread Depth | 10 32nds | 10 32nds |
1. Weight of the Tires
The weight of 245 tires is approximately 27 lbs, while that of 255 is 47 lbs. It means that 245 tires are 20 lbs lighter than 255 tires.
But it is also important that you have a heavier car to use heavy tires. Heavy tires mean better grip on the car and better road performance. Lighter cars with heavy tires can slow down the acceleration.
Heavy tires in a heavy car also mean more fuel consumption. So, it might be less economical to use heavier tires in the car.
2. Gas Mileage
As mentioned above, heavy tires consume more fuel. You can expect a decrease of 1-2 miles maximum if you go from 245 to 255 tire size. It is because the tread size of these two tires doesn’t differ greatly.
Heavier tires reduce fuel economy because they require more effort to work. Their resistance is higher, which consumes more fuel and reduces gas mileage.
So, if you want to get economical tires that don’t provide less mileage, go for the 245 tire size.
3. Car Load
245 tires can endure a maximum load of 850 kgs (1,874 lbs), and 255 tires can withstand a 900 kg load (1,984 lbs). The main point to indicate this load is to ensure that you don’t put light tires on a heavy vehicle.
While choosing the right size for your vehicle, you have to ensure that the tires can withstand the vehicle’s weight. Otherwise, the performance can become abysmal.
This information is provided by the load index mentioned in the special code for the respective tire.
4. Stability
Larger tires can provide more stability. This is extremely crucial during fast driving as more stability means a safer ride. Moreover, a more stable tire can also provide better stopping power, necessary while driving fast and on harsh roads.
The stability difference between 245 and 255 tires is not too much. But if you need some extra stability and love to drive fast, then you might want to go for the 255 tire size.
5. Maneuverability
So, in theory, 245 tires can provide slightly less handling than the 255 tires for the same vehicle.
Pros and Cons of 245 & 255 Tires

- Economical
- Great for everyday use
- Less handling
- Low rolling resistance
255 Tires
- Better handling
- Great while fast driving
- Better look for the car
- Smoother ride
- More fuel consumption

It is important to choose the right type of tire based on your driving conditions and needs.
Can I use snow tires year-round?
Snow tires are designed specifically for use in cold and snowy conditions and are not recommended for year-round use. They are made of a softer rubber compound that can wear out quickly on dry roads and can negatively impact the handling and stability of the vehicle.
What is the difference between radial and bias-ply tires?
Radial tires have a construction that features layers of steel or polyester cords that run perpendicular to the tread, providing better stability and handling. Bias-ply tires, on the other hand, have a construction that features layers of cords that run at an angle to the tread, providing a smoother ride but less stability and handling. Radial tires are more common in modern vehicles due to their superior performance and durability.
