Question:

Im interested in purchasing 12inch wheels. When it is said 4 on 4 do you measure diagonally or horizontally or vertically?

A 4 on 4 inch bolt pattern is measured diagonally on center. The first number indicates the number of lug holes and the second number indicates the diameter of the circle that those holes sit on. Check out the wheel bolt pattern help article that I attached. I have also attached a link to all of our 12 inch trailer wheels and tire/wheel combos that have a 4 on 4 inch bolt pattern for you to check out.
