Its asymmetrical tread pattern delivers confident handling in dry conditions, reliable grip on wet pavement, and capable performance in light winter weather. Backed by a strong tread life warranty and available in 36 sizes spanning 17- to 22-inch fitments, it suits drivers who want year-round versatility without sacrificing ride comfort.\u003c\/p\u003e\n\u003cp\u003eThe NT421Q uses an asymmetrical tread layout with three circumferential grooves that channel water away to reduce hydroplaning risk. Reinforced shoulder blocks improve steering response and add durability under cornering loads. A dense network of 3D interlocking sipes — concentrated on the inboard tread half — enhances grip in wet and light-snow conditions. Built-in wear indicators alert drivers to uneven or excessive tread loss before it becomes a safety issue.\u003c\/p\u003e\n\u003cp\u003eWe stock the Nitto NT421Q in 36 sizes for 17\"–22\" wheels — every size below lists its exact specs.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eAsymmetrical tread pattern supports year-round traction and flexible rotation\u003c\/li\u003e\n\u003cli\u003eThree circumferential grooves help evacuate water and resist hydroplaning\u003c\/li\u003e\n\u003cli\u003e3D interlocking sipes — denser on the inboard side — improve wet and light-snow grip\u003c\/li\u003e\n\u003cli\u003eReinforced shoulder tread blocks enhance steering response and cornering durability\u003c\/li\u003e\n\u003cli\u003eBuilt-in tread wear indicators provide early warning of uneven or excessive wear\u003c\/li\u003e\n\u003cli\u003eUp to 75,000-mile tread life warranty for H- and V-rated sizes; 60,000 miles for W-rated\u003c\/li\u003e\n\u003cli\u003eAvailable in 36 sizes covering 17- to 22-inch rim diameters for wide SUV\/CUV fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePerformance Profile\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeason Coverage:\u003c\/strong\u003e All-Season SUV\/CUV\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjected Longevity:\u003c\/strong\u003e UTQG treadwear 640 · 60,000-mile manufacturer tread-life warranty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTraction Grade:\u003c\/strong\u003e A (UTQG wet traction)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Grade:\u003c\/strong\u003e A (UTQG heat resistance)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eAbout Nitto Tires\u003c\/h2\u003e\n\u003cp\u003eNitto is a Japanese tire manufacturer with a philosophy centered on merging precise engineering with bold visual identity. The brand focuses primarily on performance and light truck tire segments, developing its products around real-world input gathered directly from drivers and enthusiasts.\u003c\/p\u003e\u003cp\u003eThat customer-driven approach is reflected across Nitto's core lineup. The Grappler series addresses off-road capability and durability for truck and SUV applications, while ultra-high-performance lines such as the NT555 G2 are built for strong traction and stability at elevated speeds on public roads.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eIs the Nitto NT421Q a good fit for my crossover or SUV?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eYes — the NT421Q is engineered specifically for CUVs and SUVs, addressing the handling, traction, and ride-comfort priorities those vehicles demand. Its asymmetrical tread and reinforced shoulders deliver responsive handling in dry conditions, while the sipe network and circumferential grooves keep it capable on wet roads and in light winter weather. Drivers looking for a well-rounded, long-lasting all-season option will find it a solid match.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the NT421Q handle snow and winter driving?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe NT421Q performs adequately in light snow, thanks to its open inboard tread grooves and dense sipe pattern that add grip on cold, slippery surfaces. However, it is not Three-Peak Mountain Snowflake certified, meaning it has not met the industry threshold for severe snow service. If you regularly drive in heavy snowfall, deep accumulation, or significant ice, a dedicated winter tire will provide meaningfully better performance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow long will the NT421Q's tread last?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eNitto backs the NT421Q with a tread life warranty of up to 75,000 miles on H- and V-speed-rated sizes, and 60,000 miles on W-rated sizes. Actual mileage depends on proper inflation, regular rotations, and driving habits. Following Nitto's recommended maintenance guidelines is the best way to reach the full warranty coverage.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the NT421Q a directional tire, and how can it be rotated?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eNo, the NT421Q uses an asymmetrical — not directional — tread design. That distinction matters at rotation time: unlike a directional tire that must stay on the same side of the vehicle, the NT421Q can be moved to any wheel position (front, rear, left, or right). This flexibility makes standard rotation patterns straightforward and helps promote even tread wear.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere are NT421Q tires manufactured?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eNitto produces the NT421Q at two facilities: its longstanding factory in Japan and its U.S. manufacturing plant located in Georgia. Both plants operate under Nitto's quality standards, so the production origin does not affect the tire's specifications or warranty coverage.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I get the full manufacturer warranty buying from TFS Wheels?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eYes.

Coverage terms vary by brand — most cover structural integrity for the life of the wheel and finish for 1 to 2 years from purchase. If you ever have a warranty question, contact us first; we work directly with the manufacturer on your behalf so you don't have to.\u003c\/p\u003e\n\u003ch2\u003eAccessories Included with Your Order\u003c\/h2\u003e\u003cp\u003eWhen you submit your vehicle information at checkout, the right \u003cstrong\u003elug nuts\u003c\/strong\u003e and (if needed) \u003cstrong\u003ehub-centric rings\u003c\/strong\u003e are automatically added to your cart in the correct sizes — no guessing, no separate ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTPMS sensors\u003c\/strong\u003e are also available in the cart. We program each sensor to your vehicle's exact year, make, model, and submodel before shipping, so they arrive ready to sync with your truck or car the moment they're installed. This typically saves customers the dealer or installer's programming fees, which often run several dozen dollars per wheel.\u003c\/p\u003e\n\u003ch2\u003eReturns\u003c\/h2\u003e\u003cp\u003eReturns are accepted within 30 days of purchase on items in new, unused condition. A 25% restocking fee applies to general (change-of-mind) returns, and the buyer covers return shipping.\u003c\/p\u003e\u003cp\u003eThe restocking fee and return shipping are waived for incorrect items, transit damage, or fitment issues when vehicle information was provided at checkout. Single wheels, single tires, mounted items, special orders, and accessories (lug nuts, locks, hub-centric rings, TPMS sensors, installation kits) are final sale.\u003c\/p\u003e\n\u003ch2\u003eNeed Help?\u003c\/h2\u003e\n\u003cp\u003eTalk to a tire \u0026amp; wheel fitment expert: \u003cstrong\u003e\u003ca href=\"tel:+18772902955\"\u003e(877) 290-2955\u003c\/a\u003e\u003c\/strong\u003e or \u003ca href=\"mailto:sales@tfswheels.com\"\u003esales@tfswheels.com\u003c\/a\u003e (Mon–Fri 9am–5pm ET).\u003c\/p\u003e","brand":"Nitto","offers":[{"title":"Default Title","offer_id":45043407650967,"sku":"210-890","price":329.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0635\/2411\/0487\/files\/nitto-nt421q-235-55r20_3.jpg?v=1773963968","url":"https:\/\/tfswheels.com\/products\/nitto-nt421q","provider":"TFS Wheels","version":"1.0","type":"link"}
