Understanding Tire Sizes
If you’re wondering what size tire is 315-70r17, it’s important to understand how tire sizes work. The first number in the sequence (315) represents the tire width in millimeters from sidewall to sidewall when it is mounted on a wheel. The second number (70) refers to the aspect ratio, which is the height of the tire sidewall as a percentage of its width.
In this case, the tire sidewall height is 70% of 315mm. The letter “R” stands for radial construction, which is the most common type of tire construction today. Finally, the last number (17) refers to the diameter of the wheel in inches that the tire is designed to fit.
So in this case, the tire is 315mm wide with a 70% aspect ratio, has a radial construction, and is designed to fit on a 17-inch wheel. Understanding tire sizes can help you choose the right tires for your vehicle and ensure that you get the best performance and safety on the road.
The Basics of Tire Sizes
When it comes to buying tires, it’s essential to understand the basics of tire sizes. The size of a tire can be overwhelming with all the numbers and letters used to identify it. However, these numbers and letters are essential in determining the right tire size for your vehicle.
The tire size includes the width, aspect ratio, and rim diameter, which is typically listed in millimeters. For instance, P215/65R15 89H. The “P” means it’s a passenger tire, the “215” is the width of the tire in millimeters, the “65” refers to the aspect ratio, which is the height of the sidewall as a percentage of the width, and the “15” represents the rim diameter in inches.
The load capacity and speed rating are also vital when selecting a tire size. Familiarizing yourself with these numbers and letters will make it easier to choose the perfect tire size for your vehicle.
What do the Numbers Mean?
Understanding tire sizes can be confusing for those who are not familiar with the numbers and letters on the sidewall of a tire. The first number indicates the width of the tire, followed by the aspect ratio, which determines the height of the tire’s sidewall as a percentage of its width. The letter “R” then signifies that the tire has a radial construction, while the next number indicates the diameter of the wheel in inches.
Additionally, there may be other letters and numbers denoting the tire’s speed rating and load capacity. It is essential to choose the correct tire size for your vehicle as incorrect sizing can affect performance, handling, and safety. Consulting your vehicle’s owner’s manual or a tire professional can help ensure you select the proper size tire for your vehicle.
Remember, choosing the right tire size is crucial for your safety and a better driving experience.

In this case, the tire has a sidewall height that is 70% of its width or 220.
5mm. Finally, the letter R stands for radial construction, which is the most common type of tire construction used today. The number 17 represents the diameter of the rim in inches.
Put together, a 315-70R17 tire has a width of 315mm, a sidewall height of 220.5mm, and is designed to fit on 17-inch rims with a radial construction. This tire size is commonly used on trucks and SUVs due to its ruggedness and off-road capabilities.
The First Number: 315
The first number in the tire size 315-70R17 represents the tire width in millimeters. A tire with a width of 315mm means that the distance from one sidewall to the other is 35cm.
The wider the tire, the more surface area it has to grip the road, which can increase traction and stability. However, it also means that the tire may not be as efficient in terms of fuel economy and may generate more road noise. When selecting tires, it’s important to consider the trade-offs between width and performance, as well as the specific needs of your vehicle and driving style.
The Second Number: 70
When it comes to understanding the 315-70R17 tire measurement, the second number is just as important as the first. The number 70 represents the aspect ratio, which is the height of the tire in relation to its width. In this case, the height is 70% of the width.
This measurement is crucial because it affects the tire’s overall performance and handling. Tires with a higher aspect ratio, such as 70, tend to provide a smoother ride due to their taller sidewalls, which absorb bumps in the road. However, they may not handle as well in turns as low-profile tires with a lower aspect ratio.
It is important to choose a tire with the proper aspect ratio for your vehicle’s intended use and driving style. So, when looking for a tire, make sure to pay attention to the second number, as it plays a significant role in the tire’s performance.
The Third Number: R17
