Hey Jerry! If you are trying to determine the wheel size you need you can measure the total diameter of your current wheels. If you are trying to determine the bolt pattern there are several ways to measure it. I went ahead and attached a picture below which shows one way to measure. I also attached two help articles which explain how to measure wheels and bolt patterns in more detail. If you need anything else let me know in the comments.

Hey Jerry, how did it go measuring your wheel diameter and bolt pattern? Were you able to confirm that your wheels match the right lug nut pattern? Your update could make it easier for the next person checking their wheel fit.
