Overall Diameter
One of the main differences between 26565R18 and 27565R18 is the overall diameter of the tires. The numbers 265 and 275 represent the section width of the tire in millimeters. The larger the number, the wider the tire. So, in this case, the 27565R18 has a slightly wider section width compared to the 26565R18.
Section Width
The section width of a tire refers to the distance from one sidewall to the other. It is measured in millimeters. In this case, the 26565R18 has a section width of 265mm, while the 27565R18 has a section width of 275mm. Therefore, the 27565R18 is wider than the 26565R18.
Circumference
Circumference measures the distance around the tire. It is an important factor to consider because it affects the overall performance of your vehicle. The 26565R18 and 27565R18 have different circumferences due to their varying section widths. A larger circumference can affect the speedometer reading and the accuracy of the odometer.

Sidewall
The sidewall of a tire plays a crucial role in providing stability and support to the vehicle. The sidewall height is represented as a percentage of the tire’s width. In this case, both the 26565R18 and the 27565R18 have the same sidewall height, as indicated by the “65” in the size.
| Tire Size | Section Width (mm) | Overall Diameter (mm) | Circumference (mm) |
|---|---|---|---|
| 26565R18 | 265 | 778 | 2447 |
| 27565R18 | 275 | 791 | 2490 |
As shown in the table above, the 27565R18 has a slightly larger section width, overall diameter, and circumference compared to the 26565R18. These differences may seem small, but they can impact your vehicle’s performance, especially in terms of speed, fuel efficiency, and braking.
Potential Effects on Vehicle
While the differences between these two tire sizes are not significant, they are still different. Generally, increasing tire size can lead to slight reductions in fuel efficiency, as the larger tire creates more rolling resistance. However, the impact on fuel efficiency may not be noticeable in daily driving conditions.
Additionally, a larger tire may affect the accuracy of your speedometer and odometer readings. With a larger overall diameter, your speedometer may indicate a slightly lower speed than your actual speed, and your odometer may accumulate fewer miles than you actually travel. It is essential to consider these factors when selecting the right tire size for your vehicle.
