Why Compare?
When it comes to choosing the right tire size, it can be overwhelming to navigate the jargon, numbers, and options available. This is why it is important to understand the different factors that make up a tire size and how they affect your driving experience. By comparing two similar tire sizes, you can make a more informed decision that best suits your driving needs.
Overall Diameter
One of the most significant differences between the 255/60r15 and 275/60r15 is their overall diameter. The 275/60r15 has a slightly larger diameter than the 255/60r15, measuring at 27.99 inches and 27.05 inches, respectively. This means that the 275/60r15 will give you a slightly higher ground clearance and a slightly smoother ride over bumps and potholes.
Tread Width
Another difference between the two tire sizes is their tread width. The 275/60r15 has a wider tread width of 10.83 inches, while the 255/60r15 has a tread width of 10.04 inches. This means that the 275/60r15 will provide more stability and grip on the road, especially in wet or slippery conditions.
Rim Diameter
The rim diameter is the size of the wheel that the tire fits onto. In the case of the 255/60r15 and 275/60r15, both sizes fit onto a 15-inch rim. However, the 275/60r15 requires a slightly wider rim than the 255/60r15. The 275/60r15 requires a rim width of 7.5 to 9 inches, while the 255/60r15 only needs a rim width of 7 to 8.5 inches.

The sidewall height is the distance between the rim and the tread of the tire. The 275/60r15 has a taller sidewall height of 6.5 inches compared to the 6.02 inches of the 255/60r15. A taller sidewall can provide more cushion and a smoother ride, but it can also reduce handling performance.
Circumference
The circumference and number of revolutions a tire makes per mile can affect your speedometer reading and fuel economy. The 275/60r15 has a circumference of 87.94 inches and will make 720.49 revolutions per mile.
While the 255/60r15 has a circumference of 84.97 inches and will make 745.66 revolutions per mile. This means that the 255/60r15 will provide better fuel economy and a more accurate speedometer reading.
Our Observation
The slight difference in overall diameter between the two tire sizes can have an impact on ground clearance and ride smoothness. The wider tread width of the 275/60r15 can provide more stability and grip on the road, especially in wet or slippery conditions. The difference in rim width required for each tire size is also important to consider when selecting the appropriate tire size for your vehicle.
The taller sidewall of the 275/60r15 can provide more cushion and a smoother ride, but it can also reduce handling performance. Finally, the difference in circumference and number of revolutions a tire makes per mile can impact your speedometer reading and fuel economy.
Overall, understanding the differences in tire size can help you make a more informed decision that best suits your driving needs, whether you prioritize comfort, handling, or fuel economy. By carefully considering all factors, you can select the perfect tire size for your vehicle and enjoy a safe and comfortable driving experience.
