Ford Motor Company has had a known issue with the truck frames cracking on the F-550 chassis. They acknowledged it by doing a recall, which either replaced or repaired the chassis frame or installed reinforcement braces if no cracks were visible. The recall expired in September of 2023. In October 2023 we noticed a crack on the frame just outside the recall reinforcement brace that Ford-certified technicians installed. We found another in November (reinforcement brace installed) and another in January (with Ford's new and improved frame produced due to a recall issue). Ford has denied making the repairs since the original warranty expired, even though this was the same related issue. We have been dealing with Ford Motor Company since October in hopes of resolving the issue but they continue to give us any resolution. The problem has not only caused a burden on our workforce but also caused great safety concerns. With Ford avoiding responsibility, they are allowing trucks to operate daily on our highway system, which becomes a safety concern for not only the driver but for many other motorists. The problem existed, but the issue was not resolved, all we are asking is that they take responsibility for making the repairs and permanently resolving the issue for the safety of all motorists.

National Traffic and Motor Vehicle Safety Act of 1966 (Safety Act), S571.120 Tire/Rim Selection, S5.1.2, requires the sum of the maximum load ratings of the tires fitted to the axle shall be not less than the gross axle weight rating (GAWR) of the axle system specified on the vehicle's certification label required by 49 CFR part 567. 567.77 requires any alterer of the vehicle to continue conformity with these requirements and assumes legal liability for certification under the Safety Act. The Siberian RV (see pic) is a customized off-road expedition vehicle manufactured by ProVan Industries, West Columbia South Carolina. They utilize a Ford F550 Super Duty 4x4 as the chassis and customize the RV to travel into off-grid extreme environments and road conditions. ProVan alters the standard Ford F550 dual rear wheel to a single rear wheel. The altered Certification Label affixed to the vehicle (see pic) establishes the rear axle GAWR at 14,706 pounds. The Tire/Wheel (Rim) assembly chosen by ProVan as their alteration is listed as a TOYO M608Z 285/70R 19.5" on a Hutchinson Beadlock Wheel. ProVan neglected to list the capacity of this tire on the Certification Label, instead filling "X" in this spot (VIOLATION). TOYO Inflation Chart determines the MAX load capacity of this tire to be 6395# at 125 psi MAX inflation (see chart). The Hutchinson Wheel has a stamped MAX inflation capacity of 120psi which lowers the load capacity of the tires to 6185# per tire. Either way the sum of the maximum capacity of the tires is either 12,790# or 12,270#. The tires are far short of the 14,706# rear axle GAWR required by the Safety Act. At 22,500 miles and roughly 50% tread wear the rear tire sidewalls developed a split in the bead seam near the rim (see pics). This unsafe tire condition was noticed and immediately pulled out of service. TOYO states this is an overload situation. ProVan refuses to take responsibility for their defective design in violation of the Safety Act. PLEASE HELP Consumer stated rear tire blewout on July 29t
