I have over 50k miles on these tires.

AWD MDX isn't easy on tires and I don't expect 70k but 50-60k is acceptable and I love these tires and will order another set.

Tires are at 50k with tread left. Zero problems.

Rides a little harsh at 35psi. Smoother at 32. Hoping to run 20k more but will be ok with 10k. Great tire for the money.

Best tire I have ever had. Period! Beats Defenders

Nothing like them. Silky, noiseless ride despite the aggressive shoulders capable of sport cornering. I once came up on a man down in the middle of my lane on a blind rise, and whipped around him like a race car driver. In a Toyota Highlander, no less. Only things better in snow and ice are dedicated winter tires.

SimpleTire as always delivers. However, as far as the tire... my biggest gripe is the tread wear. Didn't last over 15k miles. They performed as expected though on my '17 Scatpack.

Tires are fine, not sure I would ever waste my time with Simple Tire again after all the issues I had just to get my tires. Weeks and a lot of back and forth many times.

2015 Silverado factory 22" wheels. Running OE recommended air pressure resulted in cupping of tires on center tread to the point of wearing to the treadbars within 18,000 miles while outer portions of the tire have 50% more tread still. Verified air pressure on a weekly basis using high quality pressure gauge (did not have this problem with my other 2 vehicles which I maintain with the same pressure gauge). Dry braking grip is horrible with this tire on my vehicle. I would not recommend this tire for a heavy vehicle such as mine.

I am now a true believer in the Nitto brand. I bought these to replace the stock Kumho tires that came on my 2019 Hyundai Santa Fe. Just for information reasons, these tires did need some breaking in, which seemed to take about 2000 miles. The ride improved drastically compared to the previous tires that were on the car. It changed the car completely and couldn't be happier. Wet traction is also fantastic. Highly recommend Nitto to anyone.

Get technical:

The Nitto NT421Q is an all-season tire designed for crossovers and SUVs that offers drivers an innovative asymmetric tread with built-in wear indicators, an interlocking sipe design for wet or wintry conditions, and a reinforced shoulder for great handling.



Features & Benefits

  • All-season tread
  • Black sidewall
  • Inner segment of the tread improves performance in wet or wintry conditions
  • Shoulder tread blocks reinforced for accurate handling
  • Protected by Nitto's 75,000 mile limited manufacturer's tread life warranty for H- and V-rated sizes (60,000 mile for W-rated sizes)

Nitto's NT421Q is designed for sporty crossovers and SUVs and features larger reinforced tread blocks at the shoulder for responsive handling and an added layer of rubber at the shoulder for durability. The all-season tread of the NT421Q includes an asymmetric pattern with three circumferential grooves to help resist hydroplaning and a dense network of 3D sipes, with extra sipes on the tread's inboard side for winter performance. Nitto's innovative maintenance indicators are built into the tread grooves to give drivers an early heads-up to uneven or excessive tread wear.
