Do you need to replace a tire but don’t know what size to look for? Look no further than the 315-70r17 tire. But what exactly does that number combination mean? The first number, 315, indicates the width of the tire in millimeters. This means that the tire is 315 millimeters wide from one side of the tread to the other.
The second number, 70, represents the aspect ratio or the height of the tire from its rim to the outer edge. In this case, the height of the tire is 70% of its width. Finally, the “r” stands for radial construction, which is the most common type of tire construction.
The last number, 17, indicates the rim size in inches. This means that the tire is designed to fit a wheel with a 17-inch diameter. So, if you have a vehicle with 17-inch wheels, the 315-70r17 tire size should fit perfectly.

Understanding Tire Sizes
If you’re wondering what size tire is a 315-70r17, don’t worry, you’re not alone! Understanding tire sizes can be confusing, but once you break it down, it’s actually pretty simple. In this case, the first number, 315, refers to the width of the tire in millimeters from sidewall to sidewall. The second number, 70, is the aspect ratio or the height of the tire sidewall as a percentage of the width.
In this case, the sidewall height is 70% of the width, making it 220.5 millimeters in height. The “r” stands for radial construction, which is the most common type of tire construction.
Finally, the last number, 17, is the diameter of the wheel that the tire is designed to fit. So, a 315-70r17 tire is 315 millimeters wide, has a sidewall height of 220.5 millimeters, and is designed to fit on a 17-inch diameter wheel.
Breaking Down the Numbers
Understanding tire sizes can be confusing at times, especially for those who aren’t familiar with the numbers and letters printed on the sidewalls of their tires. The most important number to know is the tire’s width, which is usually listed in millimeters. This number is followed by the tire’s aspect ratio, which is the ratio of the tire’s height to its width.
The aspect ratio can tell you whether the tire has a wide or narrow profile. The next number is the tire’s diameter, which is the size of the wheel that the tire is meant to fit on. Finally, you’ll see a load index and a speed rating, which tell you how much weight the tire can support and how fast it can safely go.
Understanding all of these numbers is key to choosing the right tire for your vehicle and ensuring that you’re getting the best performance and safety possible.
Calculating Tire Size
So, you’re wondering what size tire is a 315-70r17? Well, let’s break it down. The first number in the series, 315, represents the width of the tire in millimeters. The next number, 70, is the aspect ratio.
This is the height of the tire’s sidewall as a percentage of its width. So in this case, the sidewall is 70% of 315mm, which is roughly 220.5mm.
Finally, the letter “R” simply indicates the tire’s construction (radial in this case), and the last number, 17, is the diameter of the wheel the tire is meant to fit on, measured in inches. So all together, a 315-70r17 tire has a width of 315mm, a sidewall height of 220.5mm, and is designed to fit on a 17-inch wheel.
Remember that tire size is important for maintaining the correct speedometer reading, safe handling, and fuel efficiency – so make sure you’re using the right size for your vehicle!
