I have attached an article to help with correct axle placement on your 18-foot tandem-axle trailer. Then based on correct placement, I recommend using a hanger kit like # APT5. I then recommend using the 6-Leaf Double-Eye Spring for 7,000-lb Trailer Axles - 24-7/8" Long # e64SR which will work well with the spacing of your hangers at 29-1/2 inches on center which will put your axles at 33-1/2 inches on center. See attached photo.

It sounds like you're looking for a 15" wheel that has 5 on 4-1/2 bolt pattern to fit your utility trailer. Although we do not have any wheels with a 2-3/4" pilot diameter, this only needs to match if you have hub piloted wheels. More…

For this combination, the distance between the front hanger and the center hanger should be 32 inches on center. The distance between the center hanger and the rear hanger will be 32 inches on center. This will put the axles 36-3/4 inches apart on…

The difference in tire diameter will be an additional 2-1/2 inches going from the 225/75-15 which measure 28.4 to the 235/80-16 which measure 30.9 inches. As a general rule of thumb the minimum safe distance between front and rear tires on the same…

Answer 9

I did some checking and it looks like on springs that are 25-1/4 inches in length measured from eye to eye you will want the distance from the first hanger to the second to be 29-1/2 inches, from the second hanger to the third you will need it to…

The final width (with tires) of the Dexter Trailer Axle, #35545I-EZ-89, will depend on the wheel and tire size you intend to use. You would simply add the width of one tire (assuming your wheels have a zero offset) to the 89 inch hub face dimension…

Answer 12

I understand how it would be unclear which measurement to use since the center of the axle is not the same as the center of the wheel on a torsion axle. For a single axle trailer, measure from the center of the spindle (center of wheel) to the…
