Finding the Correct Size Tire When Upsizing Wheels

Sep 1, '23

When you change the size of your wheels, it's crucial to select the correct size tires to ensure proper fitment and maintain the overall performance and safety of your vehicle. Here's a step-by-step guide on how to find the correct size tires when changing your wheel size:

  1. Check Your Vehicle's Recommended Tire Size:

    • Consult your vehicle's owner's manual, which typically contains information about the recommended tire sizes for your specific make and model. The manual may also provide information for different wheel sizes if they were offered as factory options.
  2. Use the Tire Placard:

    • Look for the tire placard on your vehicle. This placard is often located on the driver's side door jamb or inside the glove compartment. It provides information on the recommended tire size, tire pressure, and load-carrying capacity for your vehicle.
  3. Consider Plus-Sizing Guidelines:

    • If you're changing to larger wheels (plus-sizing), you can follow industry guidelines to maintain the overall diameter of the tire close to the original size. This ensures that your speedometer, odometer, and other vehicle systems remain accurate. You can use online tire size calculators to determine suitable tire sizes based on the new wheel size.
  4. Check Wheel and Tire Fitment Guides:

    • Many tire manufacturers and aftermarket wheel companies provide fitment guides that recommend compatible tire sizes for specific wheel sizes. These guides take into account the width and diameter of the new wheels to suggest suitable tire sizes.
  5. Consult a Tire Professional:

    • For the most accurate guidance, consider consulting a tire professional or visiting a tire shop. They can help you choose the right tire size based on your specific vehicle, wheel dimensions, intended use (e.g., performance, winter, all-season), and personal preferences.  Factory Wheel Replacement wheel specialists can help you find the correct size tire as well.  Contact us if you have any questions.
  6. Ensure Proper Load and Speed Ratings:

    • When selecting new tires, pay attention to load-carrying capacity and speed ratings. Ensure that the chosen tires meet or exceed the load and speed requirements specified by your vehicle's manufacturer.
  7. Adjust Tire Pressure:

    • Once you've installed the new tires, be sure to adjust the tire pressure according to the recommended values provided by your vehicle's manufacturer.
  8. Regularly Monitor Tire Wear and Performance:

    • After installation, keep an eye on your tires' wear patterns and overall performance. Uneven wear can indicate improper sizing or alignment issues, which should be addressed promptly.

Changing wheel sizes can affect your vehicle's handling, ride comfort, and appearance, so it's essential to make an informed choice based on your specific needs and preferences. Incorrectly sized tires can lead to safety hazards and negatively impact your vehicle's performance. If you're unsure about the correct tire size, it's always a good idea to seek professional guidance.
