How To Find The Correct Size Wheels For A Diamond C PSA Utility Trailer

To find the correct replacement wheels you'll need to know the diameter, width, and bolt pattern. Since we know the diameter is 15" we can move to determining the width. Typically this is printed/stamped to the backside of the wheel behind the spokes. If you can't find this then you will need to measure the width of your wheel.

To measure the width of a trailer wheel you will measure from where the tire beads will seat on the wheel. That will be from the inside of the inner wheel flange to the inside of the outer wheel flange, not from edge to edge of the wheel. If you don't want to remove the tire and decide to measure from outside edge to outside edge you'll need to take off about 1/2" to get a more accurate measurement.

To measure the bolt pattern on a wheel with an even amount of lugs ( 4-lug, 6-lug, 8-lug ) you will measure from the center of two bolt holes directly across from each other.

If the wheel is a 5-lug wheel you will measure from the center of one hole to the back edge of the bolt hole straight across from it.

I've attached one of our help articles to walk you through this process as well. Once you have these numbers we can find the corresponding fit and then give you style options.

For example, the Aluminum Sendel Series T07 Black Machined Trailer Wheel # AM97XR has a 15" diameter with a 6" width and 5 on 4-1/2 bolt pattern.
