    • Great traction in snow/ice
These tires were a close out as a new version was coming. I bought these to replace the worn original tires on my 2019 Nissan Frontier truck. Even though they look rather aggressive they are not unusually noisy on pavement...pretty quiet. The ride/handling is very good so far. We haven't gotten much snow in north central Wisconsin this winter but when the roads have been snow covered/icy these tires are very impressive. Very little slippage in 2wd and they feel nearly unstoppable in 4wd. Tires like these have a tendency to chop if not rotated regularly so I'll stay on top of that. So far very satisfied. ... show more

    • First impressions: Awesome tire
This tire was difficult to find at any of the tire installers around me. When found, their price was $50+ over this price here. Having the tires shipped to me, then taken to an installer - I still saved lots of money. But enough on the deal that this is. I have <100 miles on these thus far, so this is a preliminary review. The tires ride awesome on my 14 Silverado CC 4wd. Much better than the original Goodyear tires. I have been on dry road and wet rainy (with pools of water on the highway) and the handling was great. These tires are a little noisier than the original tires. I suspected this would be the case when I ordered them. All terrain tires will create some road noise. It is noticeable, not overbearing or loud. I'm willing to take a little road noise for an all terrain tire that is mud/snow rated. I'll update this review once the snow flies and have more miles on them. Update 4/16/2019 Having gone through a winter, and just completing a 3,000 mile highway trip here are some updates: 1) These tires are absolutely AWESOME in snow. Excellent traction. Best tire I've had on my truck for winter driving. 2) Road noise is still there after 4-5k miles. Again, not annoying, just noticeable. 3) On the highway, they road very well. Average mileage for my 5.3L V8 CC was mid to high 19mpg. Got as high as mid 20s on one tank. Not seeing as big of a hit on gas mileage as I expected. +++ Thus far, I would HIGHLY recommend this as a replacement tire for a truck. ... show more

    • Great tire
Very quiet, smooth ride, good traction. Every bit as good as Michelin in my experience. My second set, not alot of options in the 22” range. Gives the most tread and aggressive look, more traction than “city” tires.

    • Very noisy
These have been a great tire for my suv in the winter and some off road use. A little noisy on the highway but not overly bad.

    • Can I give them 9 Stars?
Had the tires mounted today and drove them around town the ride was Very Smooth, My first thought was the tire guy put 30 pounds of air in them That would explain the smooth ride. I them headed up to Lake Arrowhead, 85MPH on the freeway handled great and VERY QUITE at all speeds!!! Up the windy road to the lake and they cornered Great considering they are running 30 PSI of pressure in them, or are they?? Pushed them hard in to some corners and they complained a little but totally held their ground, felt very solid in all corners. When we got up the hill I put my pressure gauge on them and they were all filled to 38PSI!!!!!!!!!!! That nice of a ride with 38 PSI, i am very impressed( i typically run the tires on my truck at 40PSI. On the way down the hill pushing them hard in to corners while basically coasting (at 55MPH) I could barely hear the tires over the wind noise. On the straight aways down the hill, what tire noise, could not hear any tire noise over the wind noise. I put about 150 miles on them today and I think they are fantastic, if you are thinking about this tire don't think too long the price is great and the tires perform even better.

Great tire on road and light off roading. Not too much noise at all for that tread pattern.
