The Nitto NT420V LT315/45R22 is a luxury truck and SUV radial with a 121/118S service description in Load Range F. Its asymmetric tread uses larger outer blocks for dry cornering and wide grooves to channel water during wet-road driving.
Manufacturer dimensions are 33.19 inches in diameter and 12.4 inches in overall width, using a measuring rim 10.5 inches wide. Approved rim widths are 10 to 12 inches for this 22-inch wheel size. New tread depth is listed at 14.4/32 inch. This LT-metric version uses a 12-ply-rated Load Range F classification for heavier truck applications. Confirm that its capacity meets the actual vehicle requirements.
Maximum single-tire load is 3,195 lb at 80 psi. Before ordering, have a qualified installer confirm wheel compatibility, vehicle load/speed requirements, and steering and suspension clearance. Vehicle-specific fitment requires those checks; select operating inflation using the vehicle placard and applicable load/inflation guidance.
