Tire Diameter
One of the most important aspects of any tire is its diameter. The diameter of a tire determines how much contact it has with the ground. A larger diameter tire will have more contact with the ground, which means it will have more traction. The diameter of the 285 55r20 tire size is 32.34 inches.
This is a good size for many trucks and SUVs. The diameter of the 33×12 50r20 tire size is 33.02 inches. The Final difference is 0.68 inches. The difference in diameter may not seem like much, but it can significantly affect how your vehicle handles.
Section Width
A tire’s section width is the tire’s width from one side to the other. The section width of the 285 55r20 tire size is 11.22 inches. The section width of the 33×12 50r20 tire size is 12.52 inches. That’s a difference of nearly two inches.
A wider tire will provide more traction than a narrower tire. This is because a wider tire has more contact with the ground. However, a wider tire can also be more challenging to control.
Circumference
The circumference of a tire is the distance around the outside of the tire. The circumference of the 285 55r20 tire size is 101.61 inches. The circumference of the 33×12 50r20 tire size is 103.74 inches. That difference is 2.13 inches. The circumference of a tire is important because it determines how far the tire will travel in one revolution.
Revolutions Per Mile
The number of revolutions per mile (RPM) measures how far a tire will travel in one mile. The RPM of the 285 55r20 tire size is 623. The RPM of the 33×12 50r20 tire size is 610. The difference is 13 RPM. This may not seem like much, but throughout a long drive, it can add up.
Sidewall Height
A tire’s sidewall height is the distance from the edge of the rim to the top of the tread. The sidewall height of the 285 55r20 tire size is 6.17 inches. The sidewall height of the 33×12 50r20 tire size is 6.51 inches. The difference is 0.34 inches.
The sidewall height of a tire is significant because it determines the amount of contact it has with the ground. A taller sidewall will provide more contact and, therefore, more traction. However, a taller sidewall can also make the ride less comfortable.
Wheel Size
The wheel size of a tire is the diameter of the wheel that the tire is mounted on. The wheel size of the 285 55r20 tire size is 20 inches. The wheel size of the 33×12 50r20 tire size is also 20 inches. Therefore, there is no difference between the two sizes.
