Trailer Tire Is Expanding Larger than the Other Tires on a 5th Wheel Trailer

Updated 10/13/2015 | Published 10/12/2015

Question:

One of the tires on my fifth wheel is 2-3 inches more across the center than the one next to it and appears to be getting larger. I can no longer put the x-chock between them. The tread area looks more rounded than the other tire. Any ideas what might be causing this? Thank You.

I spoke with our resident tire expert about this issue. He believes that the tire sidewall has been pinched or otherwise damaged creating a weak spot on the inside. The air will take the path of least resistance and that's when you see bulges in the sides.

I recommend replacing the tire and any tires that are showing similar signs. When replacing tires make sure all the tires are the same construction (bias or radial) the same load range, and of course the same size.

If you can give me that information I can make some recommendations for you. I have included links to our tire main page and our help article on trailer tires for you.
