Thanks for reaching out Bo,

Looks like you're re-creating a mud motor, correct?

The closest match wecarry is the Steel Trailer Wheel - 8" x 7" Rim - 4 on 4 - White # AM20021. It's the widest 8 inch rim we carry in that bolt pattern.

One thing to note is that it has a 0 offset, which gives you 4" of backspacing. If your setup absolutely requires less than 4" of backspacing, we don't currently have a wider 4 on 4 rim that meets that spec.

What do you use the setup for; fishing, hunting?
