Bolt Hole Dimensions of Demco Spare Tire Carrier DM15851-76

Updated 03/09/2022 | Published 03/08/2022

Question:

I have a 4x4inch tube I would like to mount the carrier on. I saw a reference on another site that the mounting plate was set for 4inch wide x 3-3/8inch deep and then the bolts could handle 4 inch vertically. Hope Im making since. The orientation matters. Anyone have a diagram with dimensions for the top/bottom mounting plates?

When we measured the bolt hole distance, we found that they were 4-1/2" apart on center for the Demco Spare Tire Carrier for up to 4" Trailer Tongue - Black # DM15851-76.

As far as vertically, that actually doesn't matter as much, and the reason is, while it comes with 5-1/2" long, 1/2" bolts that will definitely fit a 4" tube, you can use longer or shorter bolts, they just need to be the same 1/2" diameter.
