The pilot hole in the center of your wheel is most likely just shy of 5 inches. Normally, it will measure something like 4.90 or 4.88 inches in diameter. Using a precise measurement tool like a dial caliper is the best way to determine the exact measurement of the pilot hole. I have provided a link to all of the wheel covers that we carry for you to review. If you find that one of these measurements is correct for your wheel, the Americana Trailer Wheel Center Cap - Stainless Steel - 4.88 inch to 4.90 inch Pilot, item # AM90156C, will work on your wheels.

If the pilot hole in the center or your wheel is a full 5 inches diameter, we do not have a Trailer Wheel Center Cap that will fit. You could possibly use a QuickTrim Trailer Hub Cover like item # QT545C, if you know the bolt pattern of your trailer wheels. We have an faq article that shows how to measure the bolt pattern of your wheels, see link, if this is the option you need to go with.
