Discoverer S/T Maxx

X-Ice Xi3

Pros, cons & observations

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

Tire A 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

Cons

  • 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
All owner themes in the Discoverer S/T Maxx review

Tire B X-Ice Xi3

Pros

  • Exceptionally quiet and comfortable ride quality
  • Long-lasting treadwear and durability over multiple seasons
  • Good stability and grip on dry pavement and cold winter roads

Cons

  • Squirmy feel and delayed, sluggish steering response on dry and wet roads
  • Lacks cornering grip and confidence during sharp turns
  • Performs poorly in heavy mountain snow, wet ice, and milder above-freezing temperatures

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.
