2017 HIGHLAND RIDGE FW OPEN RANGE Wheels Problems

WHILE IN MOTION (APPROX 55 MPH ON 2-LANE RURAL HIGHWAY) THE TRAILER BEGAN TO SWAY AND BECOME UNSTABLE. ON FURTHER INVESTIGATION IT WAS NOTED THE REAR DRIVER SIDE TIRE HAS COME OFF. AFTER STOPPING IT WAS NOTED ALL OF THE STUDS HOLDING THE LUG NUTS ON HAD SHEARED OFF. MECHANIC WHO MADE ON SITE REPAIR CONFIRMED IT WAS NOT DUE TO LOOSE LUG NUTS AS OTHER LUGS ON REMAINING TIRES WERE TIGHT AND ALSO DUE TO LACK OF ALUMINUM (THERE WAS NONE) IMBEDDED ON REMAINING PART OF 1 STUD. TIRE WAS NEVER RECOVERED. INSPECTION OF BROKEN STUDS BY INDEPENDANT PARTY WITH BACKGROUND IN METALLURGY DETERMINED MOST LIKELY CAUSE OF FAILURE IS DUE TO IMPROPER HEAT TREATING OF STUDS. MAJOR DAMAGE WAS CAUSED TO TRAILER AS A RESULT. I HAVE FOUND SEVERAL OTHER OPEN RANGE RV OWNERS WHO HAVE HAD SIMILAR ISSUES WITH THE WHEELS FALLING OFF WHILE IN MOTION.
