Tire Diameter
One of the most important aspects of a tire is its diameter. The diameter is what determines how tall the tire is. A taller tire will have a larger diameter, while a shorter tire will have a smaller diameter.
The 275 70r18 tires have an overall diameter of 33.16 inches, while the 33×12 50r18 tires have an overall diameter of 33 inches. This means that the 275 70r18 tires are taller than the 33×12 50r18 tires.
Section Width
Another important aspect of a tire is its section width. The section width is the width of the tire from sidewall to sidewall. A wider tire will have a more comprehensive section width, while a narrower tire will have a narrower section width.
The 275 70r18 tires have a section width of 10.83 inches, while the 33×12 50r18 tires have a section width of 12.52 inches. This means that the 275 70r18 tires are narrower than the 33×12 50r18 tires.
Circumference
The circumference is important because it determines how far the tire will travel in one revolution. A tire with a larger circumference will travel further in one revolution than a tire with a smaller circumference.
The 275 70r18 tires have a circumference of 104.17 inches, while the 33×12 50r18 tires have a circumference of 103.75 inches. This means that the 275 70r18 tires will travel further in one revolution than the 33×12 50r18 tires.
Revolutions Per Mile
Another way to think of the circumference is as the number of revolutions per mile. A tire with a larger circumference will have fewer revolutions per mile than a tire with a smaller circumference.
The 275 70r18 tires have revolutions per mile of 608, while the 33×12 50r18 tires have revolutions per mile of 610. This means that the 275 70r18 tires will have fewer revolutions per mile than the 33×12 50r18 tires.
Sidewall Height
The sidewall height is the distance from the edge of the tire to the rim. A taller sidewall will have a greater distance, while a shorter sidewall will have a shorter distance.
The 275 70r18 tires have a sidewall height of 7.58 inches, while the 33×12 50r18 tires have a sidewall height of 7.51 inches. This means that the 275 70r18 tires have shorter sidewalls than the 33×12 50r18 tires.
Wheel Size
The wheel size is the diameter of the wheel that the tire is mounted on. A larger wheel will have a larger diameter, while a smaller wheel will have a smaller diameter. The 275 70r18 tires are mounted on wheels with a diameter of 18 inches. At the same time, the 33×12 50r18 tires are also mounted on wheels with a diameter of 18 inches.
Construction Type
The construction type is the way the tire is made. The most common construction type is radial, which is denoted by the “r” in the tire size. The 275 70r18 tires are radial tires, while the 33×12 50r18 tires are also radial tires.
Our Observation
The main difference between 275 70r18 and 33×12 50r18 tire sizes is in the section width. The 33×12 50r18 tire size is 1.69 inches or about 13.5% wider than the 275 70r18 tire size. If you are looking for a wider tire, then the 33×12 50r18 is a good option. If you are looking for a tire with a shorter sidewall height, then the 275 70r18 is a good option.
Conclusion
The 275 70r18 and 33×12 50r18 tire sizes are both excellent options, depending on what you are looking for. Whichever tire size you choose, ensure it is the right fit for your vehicle.
