Pros, cons & observations

Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.

Tire A Trail-Terrain T/A

Pros

  • Low road noise for an all-terrain tire, with several reviewers calling it quieter than previous tires such as the AT3 and other all-terrains
  • Strong snow and ice performance, including a Colorado snowstorm and multiple Alps trips with up to a foot of snow
  • Comfortable, smooth ride and good handling and braking on the road

Cons

  • Poor wet-weather traction reported by several reviewers, including wheelspin, lack of confidence on wet roads and ABS activation issues
  • Some reviewers found road noise high on paved surfaces, and one called it outrageously noisy, though others found it quiet
  • Wear is faster for some owners, with one set nearing replacement after about 20,000 miles and two years

Tire B Discoverer MS

Pros

  • Exceptional traction in severe winter conditions including deep snow, ice, and slush
  • Strong off-road capabilities and mud performance unusual for a dedicated winter tire
  • Impressive tread life and overall longevity compared to competitors

Cons

  • Can develop significant road noise as the tires age
  • Potential for rough ride quality and vibrations if alignment or wear issues occur
  • Not quite equal to dedicated studded tires in extreme hardcore ice conditions without studs

How do we compare tires?

Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.

Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
