Overall Diameter
The overall diameter of the tire is a crucial factor to consider when selecting a tire size. The overall diameter of the 275/60r20 tire is 32.99 inches, whereas the overall diameter of the 265/70r17 tire is 31.61 inches.
This means that the 275/60r20 tire is larger than the 265/70r17 tire. A larger tire can improve the vehicle’s ground clearance, which can be beneficial for off-road driving. However, a larger tire may also affect the vehicle’s speedometer and odometer readings, as well as fuel economy.
Tread Width
The tread width is another essential factor to consider when selecting a tire size. The tread width of the 275/60r20 tire is 10.83 inches, whereas the tread width of the 265/70r17 tire is 10.43 inches. This means that the 275/60r20 tire has a wider tread than the 265/70r17 tire.
A wider tread can provide better handling and grip on the road, especially in wet and slippery conditions. However, a wider tread may also increase road noise and reduce fuel economy.
Rim Diameter
The rim diameter is the size of the wheel that the tire fits on. The rim diameter of the 275/60r20 tire is 20 inches, whereas the rim diameter of the 265/70r17 tire is 17 inches.
This means that the 275/60r20 tire is designed to fit a larger wheel than the 265/70r17 tire. A larger wheel can provide a better overall look and style to the vehicle. However, a larger wheel may also affect the vehicle’s handling and ride comfort.
Sidewall Height
The sidewall height is the distance between the wheel rim and the outside of the tire. The sidewall height of the 275/60r20 tire is 6.5 inches, whereas the sidewall height of the 265/70r17 tire is 7.3 inches.
This means that the 265/70r17 tire has a taller sidewall than the 275/60r20 tire. A taller sidewall can provide a smoother and more comfortable ride, especially on rough roads. However, a taller sidewall may also affect the vehicle’s handling and cornering ability.
Circumference
The circumference of the tire is the distance around the tire, and revolutions refer to the number of times the tire rotates in one mile. The circumference of the 275/60r20 tire is 103.65 inches, and the revolutions per mile are 611.3.
The circumference of the 265/70r17 tire is 99.29 inches, and the revolutions per mile are 638.1. This means that the 265/70r17 tire has more revolutions per mile than the 275/60r20 tire, which can affect the vehicle’s speedometer and odometer readings.
Our Observation
After comparing the 275/60r20 and 265/70r17 tire sizes, it’s clear that each size has its advantages and disadvantages. The 275/60r20 tire is larger and has a wider tread, which can provide better off-road performance and handling.
However, a larger tire size can also affect fuel economy and speedometer readings. The 265/70r17 tire has a taller sidewall, which can provide a smoother and more comfortable ride. However, a taller sidewall can also affect the vehicle’s handling and cornering ability.
