The degrees represents the angle of the cone that is on the wheel bolt. If they are 90 degree then the cone is a 90 degree angle made by the angle created by each side of the bolt.

A 60 degree lug bolt would have a 60 degree angle made by each sides of the lug. 60 is the more common size.

For 90 degree you would want the # RG02-040 that you referenced or for 60 degree part # RG02-020.

The trailer tire size of F78-15 is actually the modern size number of 205/75-15 and the H78-15 is the 225/75-15. When you measure the rim you actually have to subtract an inch due to the lip that does not count as diameter which is why your 15 inch…
