Determining Which Trailer Fender Size is Needed
Question:

Trailer fenders are classified by the diameter of the trailer wheels they're compatible with. For instance, the # F008583 fender you referenced works with 13 inch diameter wheels. If you're unsure of the diameter of your wheels, the last two digits of your tires size will indicate the diameter of the wheel. For example, if your tire size is 185/80-13, 13 represents the diameter of the wheel. Choosing a fender appropriate for the wheel diameter is the most important factor.
I've linked you to our selection of trailer fenders. At the top of the page, you can choose the wheel diameter, then you can use the filters on the left margin to choose the desired color, style, mounting method, etc.
If you're trying to match an existing fender, each product description of the fenders lists the length, width and height of the fender, which should make matching up with your existing fender a bit easier.
