The correct tool to use for measuring the pilot hole opening of a trailer hub is a digital caliper like part # PTW80157 to the nearest thousandth. However, based on the 2-1/4" measurement you provided you will want to use the Bearing Buddy Bearing Protectors part # BB2240SS for stainless or part # BB2240 for chrome. The stainless will resist corrosion better than the chrome.

I have attached a review video of both options for you.
