Performance : 9/10
Appearance : 10/10
Noise : 7/10
Comfort : 8/10
Price : Seems Right
Recommend : Yes
Comments : Legitimately the BEST looking tire in production. Noise and comfort level are what one would expect from a M/T tire, if not slightly better. For M/T tires they are absolutely PHENOMENAL in the snow and better than most in the rain. I rode them for a full winter smack in the middle of the snow belt north of Syracuse, NY and had zero issues with daily driving performance in the snow but also used them regularly to pull out vehicles stuck in 3-4ft of snow. Not great on gas mileage and need to be rotated every 2,000-3,000 miles to maintain even tread. Lifespan depends on driving surfaces. I had them worn down to racing slicks by 65k. Highly recommended for anyone wanting an aggressive looking M/T tire with great daily performance overall.

Price : Great Deal
Recommend : Yes
Comments : Great looking tire and very quiet for a mud tire. Good traction across the board so far. No snow or ice yet but dry/wet/mud traction very good. H2s are heavy with a short wheel base and can be tough on tires, especially front tires. So far these tires are holding up very well. They have to be rotated every 3000 miles to keep wear even, but that is true for just about any tire on a heavy truck.
