To determine the bolt pattern of your 2018 Nitro Z18 boat trailer you'll need to first count the bolt holes on your current wheel. If you have an even amount of bolt holes then you can measure from the center of one hole to the center of the hole across from it. On an wheel with an odd number of bolt holes you can pick a hole and measure from the center of it to the outside edge of one of the two bolt holes across from it. The number of holes and the measurement you get comes together to give you the bolt pattern.

For example, the Dexstar Conventional Steel Wheel with Offset # AM20504 you were looking at has 5 bolt holes and the measurement from the center of one of the holes to the outside edge of one of the holes across from it is 4-1/2", giving you a 5 on 4-1/2 bolt pattern.

I've attached an article below that goes over this in greater detail and offers some other ways to measure your wheels for the bolt pattern as well. I'll also need to know the code on the sidewall of your tires so that I can choose the correct size. If you can provide me with this information and any style/color preferences you have then I'd be happy to lay out the avail[able options.
