Question:

I have a utility trailer that has a 4 lug hub with 8 wheels on it, and Im wondering what Id need to put 12 wheels on it. Is there a 4 lug 12 wheel available or Would I need new hubs? How difficult is it to swap hubs if that is the case? Thanks in advance

We have several 12 inch wheels and wheel and tire combos for 4 on 4 hubs. I have added a link to all of them below. You should not need to change hubs, as long as they are 4 on 4 inch. Measure from the center of one stud across or caddy corner to the next stud and make sure it is 4 inches. I have included a link on how to measure for bolt pattern below.

The biggest thing to check is to make sure you have the clearance to add a taller wheel and tire. Make sure there is plenty of space to add taller wheels, especially if you have fenders above the wheels on your trailer. A 12 inch wheel and tire, like part # AM30620, is approximately 21 inches overall diameter.
