What size rims do I get?

When it comes to upgrading the wheels on your vehicle, one of the most important decisions you'll need to make is the size of the rims. The right rim size can significantly enhance the appearance and performance of your car or truck. In this article, we'll guide you through the process of determining the ideal rim size for your specific vehicle.


Understanding Rim Sizes


Rim sizes are typically expressed in a format like "17x8" or "20x10". The first number represents the diameter of the rim in inches, while the second number represents the width of the rim in inches. The most common rim sizes range from 15 inches to 22 inches in diameter, with widths varying from 6 inches to 12 inches.


Factors to Consider


When selecting the right rim size for your vehicle, there are several key factors to consider:



  • Vehicle Specifications: Check your vehicle's owner's manual or consult with the manufacturer to determine the recommended rim size range. This information is crucial to ensure the rims you choose will fit properly and not cause any clearance issues.

  • Tire Size: The rim size you choose should be compatible with the tire size you plan to use. Larger rims may require larger tires, and vice versa.

  • Wheel Offset: Wheel offset refers to the distance between the mounting surface of the wheel and the centerline of the wheel. This measurement is important to ensure the wheels fit properly and don't rub against the vehicle's suspension or bodywork.

  • Aesthetic Preferences: While functionality is the primary concern, you may also want to consider the visual impact of the rim size. Larger rims can give your vehicle a more aggressive, sporty appearance, while smaller rims may provide a more subtle, classic look.


By carefully considering these factors, you can select the perfect rim size that not only fits your vehicle but also enhances its overall appearance and performance.


Measuring Your Vehicle's Wheel Well


To determine the maximum rim size that will fit your vehicle, you'll need to measure the available space in the wheel well. Here's how to do it:



  1. Measure the diameter of the existing wheel from the inside of the tire to the inside of the tire.

  2. Measure the width of the existing wheel from the outer edge to the outer edge.

  3. Measure the clearance between the existing wheel and the suspension components, such as the brake calipers and control arms.


With these measurements, you can consult with a tire and wheel specialist or use online resources to find the maximum rim size that will fit your vehicle without causing any clearance issues.


Remember, it's always best to consult with a professional or do thorough research to ensure you choose the right rim size for your vehicle. Proper fitment is crucial for both safety and performance.
