Is 4 on 4" Bolt Pattern the Same Size as 4 on 100mm Bolt Pattern

Question:

is 4 x 4inch the same as 4x 100mm? I need a spacer to move the tire off the frame of my trailer, but have not been able to find spacers that are 4x4. Any suggestions would be appreciated. Thanks

The 4 on 4" bolt hole pattern for the Loadstar ST175/80D13 Bias Trailer Tire with 13" White Wheel # AM3S030 is a little bit larger than a 4 on 100mm bolt hole pattern so they aren't interchangeable unfortunately.

We typically try to avoid recommending wheels spacers simply because it means the tire/wheel won't be riding on the hub like it was meant to. What I recommend doing is looking for a wheel with an offset so that the wheel sits where it needs to, but can also provide some clearance. Unfortunately we don't carry any with the 4 on 4" bolt pattern.

Aside from that your only other option really is to get a different axle that has a longer hub-face dimension.
