This model or the
Bulldog QD22 Caravan Clamp will both be suitable for the horse trailer with the tyre sizes given.
When we refer to the wheel having no trim, we simply mean that it is a steel wheel without the plastic wheel trim attached. Wheel trims when fitted do come in different cosmetic styles and in some cases can protrude quite extensively from the face of the wheel, we refer to these as having a bulbous trim, when they do not, we refer to them as having flat trim.
