Adding Larger Wheels to Trailer Hub Assembly with Same Bolt Pattern

Updated 05/21/2014 | Published 05/20/2014

Question:

I am looking at 8-259-5UC1-EZ. It says they are for 8-12 inch wheels. Is there some reason it wouldnt work for bigger wheels as long as the bolt pattern is correct? I ask because I have hubs similar to this and want to put bigger 13inch or 15inch wheels on but want to make sure the wheels work for the hubs.

You can add larger wheels to a trailer as long as you have the same bolt pattern and enough room for the larger size. The main clearance issues we find when putting larger wheels on a trailer is from the top of the tire to the fender and from the inside wall of the tire to the trailer wall/frame.

Also you will want to keep the weight capacity in mind. Larger tires will typically have a higher weight rating. Tires with a higher weight rating will not increase the load carrying capacity of the trailer, so you will still be limited to the weight capacity of the axle. Larger wheels and tires will not have an effect on the hub as long as the bolt patterns match and you remain under the weight capacity of the axle.
