SIPING

Siping is one of the most important tire technologies for wet and snow traction. Nitto's revolutionary 3D multiwave and 3D Interlocking sipe design provide traction without sacrificing handling.

FEATURES & Benefits

For when the going gets rough

ADDED SHOULDER INSERTS

The circumferential rubber shoulder insert adds an additional layer of strength to help you navigate potholes and other adverse road conditions.

FEATURES & Benefits

Precision through the turns

TREAD BLOCK STABILITY

The NT421Q helps you safely navigate corners because the larger tread blocks on the exterior of the tire provide stability.

FEATURES & Benefits

Rain can't ruin your day

WET TRACTION

The NT421Q is an all-season tire that keeps you safely connected to the road in inclement weather. The three wide and deep circumferential grooves improve water evacuation, providing increased wet handling and traction.

FEATURES & Benefits

Cut through winter

WINTER TRACTION

The inside tread area of the tire was designed for wet and winter weather performance. The large, open grooves provide lateral water evacuation while the high sipe density increases the number of biting edges contacting the road.

    Overall a very good tire

    2007 Dodge Nitro 245/50R20. Had these for 7 years, and they are coming off tomorrow after 89k miles. Should have replaced them a year ago, but the Nitro isn't driven as much as it use to be. On my vehicle they are stiff, but this size is load rated 105, instead of the factory 102. Wet traction is good, but always could break loose when in RWD. Good wet stopping and hydroplaning resistance as well. Handles Ohio weather well, only using 4x4 after several inches of snow. Probably would work fine for FWD applications. Good highway manners with precise handling inputs, no sidewall roll or flexing issues. Probably not the tire you want if you are looking for a soft cloud feel. I need replacements immediately, so I'll have to go with a different tire that is in stock locally.

    Love them

    Had put these on my wife's Mercedes and was so happy I also put them on my Ridgeline. ride better, traction better in wet and snow. Quieter. Wife has 40k on hers and I have 15k on mine.

    Worst tires

    25 years of driving, these are hands down the worst tires I have ever owned. I thought I was stepping up to Nittos...big mistake. Put them in my wife's Explorer and very unhappy. Its like they get a flat spot from sitting over night. It takes about 30 minutes on the highway for them to somewhat loose the lumpiness. With 90% of the driving being in town, most outings are a bumpy ride. Month and a half and I want to throw them away. Nitto 210850 NT-421Q 275/45-20
