What Does 285/75r16 Mean?
The first number, “285,” refers to the Tire’s width in millimeters. The second number, “75,” is the aspect ratio, which is the height of the tire sidewall as a percentage of the width. The “r” in this case stands for “radial,” which is the type of tire construction. The last number, “16,” is the wheel diameter in inches.
What Does 285 70r17 Mean?
The first number, “285,” still refers to the width of the Tire in millimeters. The second number, “70,” is still the aspect ratio, but it is a lower percentage than the 75 in the other size.
This means that the Tire’s sidewall will be shorter than the width. The “r” still stands for radial, and the “17” is the wheel diameter in inches. Again, this is a standard size for many vehicles.
As you can see, both sizes have the same width in millimeters. This is one area where they are identical. However, there are some differences in the other aspects of the tires. Let’s take a look at those now.
The aspect ratio is the height of the sidewall as a percentage of the width. As we mentioned before, the first number in each size refers to the width in millimeters. To get the sidewall’s height, we multiply that width by the aspect ratio. For example, the 285/75r16 has a width of 285mm. If we multiply that by the 75 aspect ratio, we get 213.75 mm.
This is the height of the sidewall. The 285/70r17 has a width of 285mm and an aspect ratio of 70. This gives us a sidewall height of 199.5 mm. As you can see, the 17-inch wheel diameter has a taller sidewall than the 16-inch wheel diameter.
Tire Construction Type is the way the Tire is put together. The “r” in both of these sizes stands for radial. This is the most common type of tire construction. Radial tires are made with plies that run perpendicular to the direction of travel. This gives them a higher level of durability and a smoother ride.
There are other types of tire construction, but radial tires are by far the most common. Radial is a good choice if you need clarification on what kind of Tire you need.
The wheel diameter is the last number in each size. This refers to the diameter of the wheel in inches. As we mentioned before, the 16-inch wheel is a standard size for many vehicles.
The 17-inch wheel is becoming more popular but is less common than the 16-inch. In this example, The rim diameter of 285/75r16 tires is 16 inches, and the rim diameter of 285 70r17 tires is also 17 inches.
The circumference of a tire is the distance around the outside of the Tire. To calculate this, you need to know the width, aspect ratio, and wheel diameter. The circumference of the 285/75r16 is 103.14 inches. The circumference of the 285/70r17 is 102.76 inches. As you can see, the difference in circumference is a little small.
Revolutions Per Mile
The number of revolutions per mile (RPM) measures how far the Tire will travel in one mile. This is important to know because it can affect your fuel economy.
To calculate the RPM, you need to know the Tire’s circumference. The RPM of the 285/75r16 is 381.71 miles, and the RPM of the 285/70r17 is 383.14 miles. As you can see, the 17-inch Tire will travel slightly further in one mile than the 16-inch Tire.
The main difference between 285 75r16 and 285 70r17 Tire is the Aspect ratio and Wheel diameter. Other than that, they are almost the same. So, choose the one that fits your car the most! After looking at all the aspects of these two sizes, it’s clear that they are very similar. The only significant difference is the height of the sidewall.
The 17-inch Tire has a taller sidewall, which can give you a smoother ride. If you’re looking for a new set of tires, either of these sizes would be a good choice. If you have any questions, feel free to leave a comment below. We’re always happy to help. Thanks for reading!
