I sent an email to Mikes hubcaps...
Hi,
I'm looking for hubcaps that would fit a utility trailer. They are 4.80 x 12" tire with 5 hole on 4-1/2 bolt pattern. This is a Carry-On Corporation trailer that is being used as the base for the construction of a teardrop style camper. I would like to dress up the wheels but I'm unsure as to whether there caps that would fit.
Our 12" racing disc's should fit your wheels. Hubcap Mike
