Price is for ONE tire/wheel assembly. New 20.5X8.0-10 Hi-Run brand trailer tire mounted on a new white painted 4 hole wheel with 4" bolt circle. These are load range E tires which are 10 ply rated to carry a max of 1535 lbs per tire at 90 psi. MEASURE YOUR WHEEL BEFORE ORDERING. This is a standard size 4 hole bolt pattern used on factory made trailers. Measuring a 4 hole wheel is pretty simple, you just measure the distance between two lugs and it should be exactly 4" see last picture. The center hole size is roughly 2 3/4" however the center hole does not have to be the exact same size as your hub. It just needs to be large enough to go over it so the wheel can seat flat against the hub. These trailer wheels are stud piloted, that is they center on the tapered face of the lug nuts or bolts when tightened not the center hole.
