How To Measure Wheel Size

Measuring your vehicle's wheel size is an essential part of ensuring that your vehicle is not only performing at its optimal level but looks its best as well. With so many different wheel sizes available, it's important to choose the correct size for your vehicle to ensure both performance and safety. In this blog post, Velgen Wheels will explain the basics of measuring wheel size.

What Is Wheel Size?

Wheel size refers to the diameter of the wheel rim in inches. A wheel with a diameter of 18 inches, for example, will have a rim with a diameter of 18 inches. In addition to the diameter, the width of the wheel is also important to know. The width of the wheel is measured from one side of the rim to the other and is usually measured in inches.

Why Is Wheel Size Important?

Choosing the correct wheel size is crucial for several reasons. First, it affects the overall performance of your vehicle. A larger wheel can help improve handling and traction, while a smaller wheel can negatively impact handling and braking.

Additionally, the incorrect wheel size can cause damage to your vehicle, such as rubbing against the fender or causing the tires to wear unevenly. It can also result in tire failure, which can be potentially hazardous for both you and your vehicle.

How to Measure Wheel Size

Measuring wheel size is relatively straightforward, and can be done with a few pieces of equipment. Here are the basic steps:

Step 1: Get the Right Tools

To measure the wheel size, you will need the following tools:

• Measuring tape or large ruler (meter stick)
• Wheel gauge
• Optional: Calipers

Step 2: Measure the Rim Diameter

The first step in measuring your wheel size is to measure the rim diameter. To do this, take your measuring tape or ruler and measure the distance from one side of the wheel rim to the other. Be sure to measure at the widest point of the rim.

Alternatively, you can use a wheel gauge to measure the rim diameter. A wheel gauge is a tool designed specifically for measuring the diameter of a wheel rim. It has arms that extend out and can be placed against the rim to take the measurement.

Step 3: Measure the Rim Width

The next step is to measure the rim width. This can be done using either a measuring tape or ruler. To measure the width, place the measuring tape or ruler against the inside of the rim and measure from one side of the rim to the other.

Alternatively, you can use calipers to measure the rim width. Calipers are a more accurate tool for measuring the width, as they can measure to within a hundredth of an inch.

Step 4: Check the Bolt Pattern

In addition to the diameter and width, you also need to know the bolt pattern of your vehicle. The bolt pattern refers to the number of bolts on the wheel hub and the distance between them.

To measure the bolt pattern, first, count the number of bolts on the wheel hub. Then, measure the distance between them by measuring from the center of one bolt to the center of the bolt directly across from it.

Conclusion

Measuring the wheel size of your vehicle is an essential part of ensuring that your ride is performing at its optimal level. Knowing how to measure wheel size, diameter, and bolt pattern can help you choose the proper wheels for your vehicle and help prevent damage. Whether you are upgrading your vehicle, replacing a damaged wheel, or buying new tires, taking the time to accurately measure your wheel size will ensure that you get the best performance possible.
