How to Determine the Correct Replacement Trailer Wheel for a Little Guy 5x8 Silver Shadow

Your trailer probably does have conventional steel wheels or otherwise regular trailer wheels. To determine which wheel is the correct one for your trailer you will need to look at a few things. First you will want to look at the size of the existing wheels. You will need to measure the diameter of the wheel and the width from bead seat to bead seat. The tire has to be removed for the width. I can also determine the size of the wheel if you can tell me the tire size.

You will also need to measure the bolt pattern. I have included a link to an FAQ article on measuring for bolt pattern.

You will also need to determine if the existing wheels have an offset. An offset will move the wheel closer or further from the trailer depending on if it is a negative or positive offset. Wheel # AM20304 has a positive offset of 1/2 inch. This means the mounting surface of the wheel is further out and this moves the tire closer to the trailer.

To determine if there is an offset you can measure from the mounting surface out to the edge of the wheel at the front and back. The easiest way to do this is to lie a flat object like a yardstick across a wheel (with NO tire on it) then measure from the mounting surface to the yardstick. If both sides are the same then it is a zero offset. If the front side is less then it is a positive offset. And if the back side is less it is a negative offset. I have included some links that should help.
