Tire B Discoverer S/T Maxx

Pros

  • Aggressive all-terrain tread pattern that excels in dirt, gravel, sand, and moderate mud
  • Surprisingly quiet and smooth ride on the highway for such a rugged tire
  • Exceptional sidewall strength and puncture resistance against sharp rocks and debris

  • Faster-than-expected tread wear for some users, particularly on heavier duty or lighter vehicles
  • Subpar wet pavement traction, specifically in cold or greasy conditions
  • Stiff ride quality and potential handling vagueness or steering pull if pressures are not meticulously tuned

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.

Community buzz from Reddit and forums is shown for context only — it never changes the score.
