The 33×12 50r17 tire size is a metric tire. This means that the first number, 33, is the tall or diameter of the tire. The second number, 12.50, is the width of the tire which is in inches. The last number, 17, is the diameter of the wheel that will fit this tire. This size is most commonly used on Jeeps, trucks, and SUVs. The “R” in size means that it is a radial tire.
The first number in tire size, such as 33 in 33×12 50r17, is the diameter of the tire. This is also called the “tall” of the tire. The diameter of the 285 70r17 tire size is around 32.71 inches. The difference between those is 0.32 inches or 1%.
The height of the tire will affect the ground clearance of your vehicle as well as the turning radius. A taller tire will have a larger diameter and will be more comprehensive than a smaller tire. A smaller tire will have a smaller diameter and will be narrower than a taller tire.
Another number in tire size is the section width. This number refers to the width of the tire from one side to the other. The section width of a 285 70r17 tire is 11.22 inches. The section width of a 33×12 50r17 tire is 12.52 inches.
The section width will affect the amount of grip that the tire has as well as how stable the tire is when cornering. A wider tire will have more grip and be more stable when cornering than a narrower tire.
The last number in tire size is the circumference. This is the distance around the outside of the tire. The circumference of a 285 70r17 tire is 102.76 inches. The circumference of a 33×12 50r17 tire is 103.75 inches.
The difference between those is 0.99 inches or 1%. A larger circumference tire will have a higher gear ratio and a lower speedometer reading than a smaller circumference tire.
Revolutions Per Mile
The number of revolutions per mile (RPM) is how many times the tire will go around in one mile. The RPM of a 285 70r17 tire is 616, and the RPM of a 33×12 50r17 tire is 610. This difference is not significant.
The sidewall height is the distance from the edge of the wheel to the top of the tire. The sidewall height of a 285 70r17 tire is 7.85 inches, and the sidewall height of a 33×12 50r17 tire is 8.01 inches. The difference between those is 0.16, or about 2% of the total height.
The sidewall height will affect the amount of flex that the tire has as well as the ride quality. A taller sidewall will have more flex and a smoother ride than a shorter sidewall.
Rim size is the diameter of the wheel that the tire will fit on. The wheel size for a 285 70r17 tire is 17 inches, and the wheel size for a 33×12 50r17 tire is also 17 inches. The difference between those is 0%.
The wheel size will affect the width of the tire that can be used as well as the diameter of the tire. A larger wheel will allow for a wider tire but a smaller diameter tire. A smaller wheel will allow for a narrower tire but a taller diameter tire.
The “R” in the tire size means that it is a radial tire. This is the most common type of tire construction. The other type of tire construction is called bias ply. Bias-ply tires are not as common as radial tires. Radial tires have plies that go from the bead to the tread in a radial or side-by-side direction.
The main difference between 285 70r17 and 33×12 50r17 tire sizes is in the section width. The section width of a 33×12 50r17 tire size is 1.3 inches or 11.6% wider than a 285 70r17 tire size. That means that the 33×12 50r17 tire will have more grip and stability when cornering.
