Nitto NT421Q 245/60R18

The Nitto NT421Q is a performance and high-performance, all-season tire manufactured for SUVs. The asymmetric tread pattern features a 3D multi-wave interlocking siping detail which ensures excellent dry, wet and winter weather road gripping ability. Nitto offers a 60,000 miles treadwear warranty with the W speed rated sizes and a 75,000 miles treadwear warranty with the H and V speed rated sizes of this tire model. The NT421Q’s special tread pattern also extends the tire’s usability and tread life. The tread design evenly spreads the driving pressure out across the entire tread area to prevent irregular wear patterns from forming. Uneven tread wear is also combated by the tire’s Maintenance Indicators. The special tread design and the extra strength layer boosts the tire’s handling.
