Nitto NT421Q Review

The NT421Q is a premium all-season tire from Nitto that’s built specifically for the needs of modern crossovers and SUVs, with an added layer of style that you won’t find in most all-season tires.

PROS

  • Great wet traction
  • Comfortable
  • Quiet
  • Long life

CONS

  • Can be expensive depending on the size

The tread pattern is certainly unique with an aggressive flare. It does more than just look good though with three large circumferential grooves designed to evacuate water and prevent hydroplaning. Plus, there’s extensive siping, particularly on the inside treads of the tire, to further help remove water.

That same siping, particularly on the inside of the tire, results in an increase in biting edges. This helps give this all-season tire a touch more winter traction than it would otherwise – although we always recommend purchasing actual winter tires if you live in a colder climate.

The exterior of the tire features larger tread blocks for dded stability in cornering, helping your high-riding SUV take corners with more confidence and poise.

In addition, the exterior of the tire also features added rubber padding in the tire’s structure to help strengthen the tire and prevent against damage from potholes and rough roads. Overall it’s a very comfortable tire and a quiet one too.

One particularly unique feature of the Nitto NT421Q are the tires maintenance wear indicators that run along the tire’s large circumferential grooves. They give a visual cue to how much tread life is left and also help warn of uneven wear as a result of alignment or possible suspension issues. We really enjoy this feature, as issues like these can drastically reduce the life of your tires.

Reviews on Nitto’s website give theNT421Q tire a 4.5 out of 5 rating, while 90.8 percent of reviewers on the Discount Tire website recommend this tire.

How Long to Nitto NT421Q Tires Last?

You should expect to get roughly 60,000 to 75,000 miles on a set of these tires, which is impressive on the high end. Achieving that number won’t happen if you’r an aggressive driver. It also assumes proper tire rotation and inflation procedures are adhered to.

Is the Nitto NT421Q Good in Snow?

We rate the Nitto NT421Q tire slightly above average for an all-season tire when it comes to winter performance. We’d add that all-season tires are really not designed for use in real cold or in much snow. This tire, as it’s designed more specifically for crossovers, features plenty of added siping to maintain a high level of grip in different environments. The heavy siping on the inside of the tire, gives extra grip in the wet and delivers some level of light snow grip. Ultimately, however, all season tires tend to freeze up in colder temperatures and performance drops off very quickly.
