Nitto builds the Trail Grappler M/T LT295/55R20 for light-truck mud-terrain use with attention to on-road comfort. The 123/120Q service description and load range E distinguish this 20-inch fitment.
Published dimensions are 32.91 inches in diameter and 12.52 inches in inflated width on a measuring rim 9.5 inches wide; approved wheel widths run from 8.5 to 10.5 inches. New tread depth is listed at 19.4/32 inch. Reinforced three-ply sidewalls support the design on this size. Two sidewall appearances let you choose between stylized lettering with V-shaped lugs and traditional lettering with flatter buttresses.
The maximum single-tire load is 3,415 lb at 80 psi. Match the size, wheel dimensions, load and speed requirements to your vehicle, then have a qualified installer check steering and suspension clearance. Published dimensions are a planning reference, not a vehicle-specific fitment guarantee; maximum pressure is not the recommended operating pressure.
