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.
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.
Tires dont last 20,000 miles. Dont buy them
I have these about a month on my Infinity FX, so far outstanding. Ride is smooth and quite. Has not rained so I cannot comment on wet handling. I had Michelins Premiers on it before, but I got tired of them wearing out quickly given the price. I actually think these Nittos ride better.
So far they have been great. I am much happier than these than the Michelin's we had. But time will tell.
I have a 2006 Volvo XC90 front wheel drive. The Nitto NT421Q transformed the car, its ride and handling. So much smoother, quieter than previous tires. Handling is smooth and precise. Way too early to tell about tread-life, but so far, loving them.
Put these on a 2011 Acura MDX replacing the original Bridgestones Rides and handles like a different vehicle. Sharper turning and better handling. Went from truck-like to sporty.
Great tire for a great price at Simple Tire. I have these tires on a 1500 Sierra Truck and the ride and noise are excellent.
