Price is per tire/wheel assembly. Order qty 1 = 1 tire mounted on a wheel ready to bolt on. New 18.5x8.50-8 Deestone brand D268 trailer tire on a new white painted 4 hole wheel with 4" bolt circle. This is a load range C tire which is 6 ply rated to carry a max of 940 lbs per tire at 50 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.
