Thank you for providing your ruler measurement. I am sure that your ruler measurement is pretty close. However, these various cap dimension run very close and they are intentionally a snug fit, so accuracy is critical. The pilot hole of the wheel really needs to be measured with a micrometer to ensure proper fit.
I did some research on your Sierra 37sp and found that the factory wheels are 16 inches. Your wheel bolt pattern will determine which trailer wheel center cap to use.
I pulled one of the Excalibur Trailer Wheel Center Cap # 490EZ-SS and three different wheels to test fit the cap. I found that this cap perfectly fit our Dexstar Wheel # AM20750, which has a pilot hole diameter of 4-3/4 inches and a 8 on 6-1/2 bolt pattern.
We also offer # AM90156C which fits 4.88 to 4.90 pilot holes.
