From owners

Pros, cons & observations

Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.

Tire A Kumho Road Venture AT51

The Kumho Road Venture A/T51 is widely regarded as a high-value, all-terrain tire that excels in noise reduction and comfort compared to more aggressive competitors. While most users praise its performance in snow, rain, and gravel, a minority of owners report issues with uneven wear, balancing difficulties, and durability concerns.

Pros

  • Exceptional noise levels for an all-terrain tire
  • Strong value proposition and competitive pricing
  • Reliable traction in snow, ice, and wet conditions
  • Comfortable ride quality on various road surfaces

Cons

  • Reports of premature tread wear and cupping
  • Occasional balancing issues causing vibrations
  • Some concerns regarding puncture resistance
  • Inconsistent performance in deep mud

Observations

  • Users transitioning from more aggressive tires (like the BFG KO2) on Jeeps and trucks frequently report a significant improvement in cabin quietness.
  • Heavy-duty truck owners occasionally report ride quality issues, such as shaking or bouncing, which may be sensitive to specific PSI adjustments.
  • The tire is noted for maintaining good performance characteristics on both older SUVs and modern electric vehicles.
Tire B Toyo Open Country A/T II

The Toyo Open Country A/T II is widely regarded as a versatile, durable, and quiet all-terrain tire that excels in mixed-use scenarios, including towing and light-to-moderate off-roading. While the vast majority of users praise its longevity and highway comfort, a subset of owners reports persistent issues with high-speed balancing and inconsistent performance on slick, wet pavement.

Pros

  • Excellent highway comfort and low road noise for an all-terrain tire
  • Strong off-road capability in mud, sand, and loose rock
  • High durability and tread life when properly maintained
  • Predictable handling and stability while towing heavy loads

Cons

  • Persistent reports of vibration and difficulty achieving a proper high-speed balance
  • Inconsistent traction on wet or freshly rained-on pavement
  • Potential for uneven tread wear if rotation and pressure are not strictly managed
  • Some users find the compound too stiff for optimal grip in icy or packed snow conditions

Observations

  • Heavy-duty truck owners (e.g., Ram 2500/3500) report excellent towing stability, provided tire pressures are adjusted using the 'chalk test' to prevent center-tread wear.
  • Users opting for 'C' load ratings on lighter vehicles like the Jeep Wrangler report a more comfortable ride but note 'squishy' sidewalls during off-road deflation compared to 'E' load versions.
  • Owners of smaller SUVs and crossovers (e.g., Subaru Crosstrek) generally find the tire to be a significant aesthetic and functional upgrade over stock tires with minimal noise penalty.

How do we compare tires?

Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements) normalized against the best tire in each test and weighted toward recent tests. 40% comes from thousands of owner reviews collected from retailers and review sites. When a tire has only one of the two, we use what exists and say so.

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