Price is for TWO tire/wheel assemblies, sold as a pair. Order qty 1 = 2 tires mounted on wheels ready to bolt on. New 5.70-8 Hi-Run brand SU02 highway use DOT approved trailer tires on new white painted 4 hole wheels with 4" bolt circle. These are load range D tires which are 8 ply rated to carry a max of 1075 lbs per tire at 100 psi. MEASURE YOUR WHEEL BEFORE ORDERING. This is the standard size 4 hole bolt pattern used on most modern factory made trailers. To measure bolt circle on a 4 hole pattern you measure the center to center distance between two lugs located directly across from each other. Center hole size is approximately 2.50". The center hole size does not have to be the exact same size as the hub, these small trailer wheels are stud piloted meaning they center off the taper of the lug nuts or wheel bolts when tightened and the studs or wheel bolts carry the load not the center hole. The center hole just has to be large enough to go over the hub and allow it to seat against it.
