One of TrailReady Products' offerings is this HD17 wheel. It is available in a variety of bolt patterns and measures 17x8.5. Backspacing of 3.5 to 4.5 inches is available. TrailReady says it is a purpose-built wheel for off-road competition motorsports. It is pressure-cast with an extra thick back bead to resist inside bead failure commonly caused when rocks are driven between the brake bell and caliper. The bead-lock ring is manufactured from 6061 T6 aluminum and is secured with 24 countersunk 5/16-inch, Grade 8 bolts.
