The Nitto NT555 G2 285/30ZR20 pairs a 99W service description with a summer tread designed for performance-focused road driving. This exact size carries an XL (Extra Load) designation. Twin center ribs help steady the tire in a straight line, while tapered tread blocks and reinforced shoulders support cornering. Its nominal width places it in Nitto's 275-mm-and-wider group, which uses larger tread blocks than the 265-mm-and-narrower sizes.
This 20-inch fitment has approved rim widths of 9.5 to 10.5 inches. Nitto lists a 26.77-inch inflated diameter and 11.42-inch overall width with a measuring rim width of 10 inches. New tread depth is 11/32 inch. Center and shoulder grooves help move water through the tread during summer road use.
Maximum single-tire load is 1,709 lb at 50 psi. Before ordering, have a qualified installer confirm wheel compatibility, required load and speed ratings, and clearance throughout steering and suspension travel. Set operating inflation using the vehicle placard and applicable load/inflation guidance.
