The 255 and 245 tires are widely used. If you have 245 factory-fitted tires, when changing your vehicle tires, one of the questions you may have is whether I can install 255 tires instead of 245.
Using different size tires slightly changes the fuel economy, braking distance, and traction. More and more people use wider tires to improve the aesthetics and performance of their vehicles, and there are several factors you must consider before using different size tires.
This article will discuss; “can you put 255 tires on 245 rims?” (interchangeable) What is the difference between 245 and 255 tires?

Can you put 245 tires on 255 rims?
Yes, you can put 245 tires on 255 rims. The 245 and 255 tires are interchangeable if you have 9.0-inch wide rims. Furthermore, you can interchange these two tire sizes with 8.5-inch and 9.5-inch wide rims, but these extreme rim options can cause the tire to be too tight or too loose on the rim. If you downsize the tire for money savings, it’s not worthwhile. You will sacrifice grip and traction and increase braking distance.
You can use our free tire size calculator to check your current tire and new tire difference. Reviewing our rim size calculator recommendation when replacing new tires is worthwhile.
Can you replace 255 tires with 245 tires?
Yes, you can replace 255 tires with 245 tires if you have 8.5-inch to 9.5 wider rims. The optimal size is a 9-inch wide rim. The 255 is a slightly wider tire that improves grip, driving comfort, and handling performance and enhances its appearance. Moreover, it slightly increases fuel consumption than 245 tires.
The 245 and 255 tires are interchangeable, and you can easily interchange them if your car, SUV, or truck has 9 inches factory-fitted rim. The 8.5 and 9.5 wide rims are more extreme options, and those sizes can cause the tire to fit too tightly or too loosely with the rim.
The wider tires provide more grip and shorter braking distance. You can get a better handling performance by putting wider tires rear and slightly narrow tires front (staggered setup).
Using our tire size calculator, you can measure the difference between your new and old tires. Also, you can use a rim size calculator to check if your current rim width fits these two tire sizes.
What is the difference between 245 and 255 tires?
The difference between 245 vs 255 tires is the width. These two digits are the width of the tire in millimeters. The 245 tire width is 245 mm (9.6inch), and the 255 tire width is 255 mm (10 inches). We can find tires of different aspect ratios and rim sizes, and the overall diameter, circumference, and sidewall height revs per mile change depending on aspect ratio and rim size. You can use our tire calculator to get the exact difference according to your tire’s rim size and aspect ratio.
Wider tires enhance the vehicle’s sporty look and slightly improve handling performance.

FAQ.
255/35 Vs 245/40.
The main difference between 255/35 vs 245/40 is tire width and sidewall height. The first three digits are the tire width in millimeters, and the two numbers right after the slash are the aspect ratio. The 255/35 specification is 255 mm (10 inches) in width, and the sidewall height is 89 mm (3.5inches). The 245/40 specification is 245 mm (9.6inches) in width, and the sidewall height is 98 mm (3.9 inches). You can use our online tire size calculator to know if these tires are interchangeable.
| Parameter | 255/35 | 245/40 | Difference |
|---|---|---|---|
| Section width | 255 mm (10 inches) | 245 mm (9.6 inches) | 10 mm (0.4 inches) (4%) |
| Sidewall height | 89 mm (3.5 inches) | 98 mm (3.9 inches) | 9 mm (0.3 inches) (10%) |
245/45 Vs 255/45.

What size rim for 255 tires?
The optimum rim width for 255 tires is 9 inches, but you can use 8.5-inch to 9.5 wider rims. The 255 tires are made of different diameter rim sizes so that you can choose different sizes. The rim height is not an issue for select 255 tire sizes.
What size rim for 245 tires?
The ideal rim width for 245 tires is 9 inches, but you can fit 8.5 and 9.5 size rims. You only need to worry about rim width, as the diameter does not affect selecting wider or narrow tires. These tires have various diameter sizes, so you must choose the rim diameter accordingly.
Conclusion.
245 and 255 are interchangeable tires without changing the rim. If you have 8.5, 9, or 9.5 inches wider rims, you can, but the optimum rim width is 9 inches. The 8.5 inches is too tight, and the 9.5 can be slightly loose. The difference between 255 and 245 tires is 10mm (0.4inches) in width, which is a 4% difference. These tires have different aspect ratios and rim sizes. Therefore its sidewall, diameter, circumference, Revs per mile, and ground Clearance change accordingly.
The 255 tire is wider, has a shorter braking distance, better traction and grip, and performs better on dry surfaces. However, it has a higher tendency to hydroplane, more noise generated, and slightly higher fuel usage. The 245 is a somewhat narrow tire, and it is suitable for wet and snow driving conditions, less prone to hydroplane, and has cheaper and better fuel economy. However, it is less comfortable, has a slightly longer braking distance, and generates more heat than wider tires. These are the general benefits of wider vs narrow tires.
