The Nitto NT420V 275/60R20 is a luxury truck and SUV radial with a 116H service description and an XL (Extra Load) designation. Its asymmetric tread uses larger outer blocks for dry cornering and wide grooves to channel water during wet-road driving.
Manufacturer dimensions are 32.99 inches in diameter and 10.98 inches in overall width, using a measuring rim 8 inches wide. Approved rim widths are 7.5 to 9.5 inches for this 20-inch wheel size. New tread depth is listed at 12.2/32 inch. The non-directional pattern allows cross-rotation where the vehicle and tire configuration permit it. A qualified tire retailer should determine the appropriate rotation pattern.
Maximum single-tire load is 2,756 lb at 50 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.
