From owners
Pros, cons & observations
Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.
The Kumho Road Venture A/T KL78 is widely regarded as a high-value, all-terrain tire that excels in noise suppression and daily road comfort. While most users praise its balanced performance across various surfaces, a minority of owners report issues with ride quality and consistency, suggesting that performance may vary depending on vehicle weight and suspension setup.
Pros
- Exceptional value for the price point
- Surprisingly low road noise for an all-terrain tread pattern
- Strong dry pavement traction and highway stability
- Reliable performance on gravel and light off-road surfaces
Cons
- Reports of ride harshness or vibration on heavier-duty trucks
- Potential for uneven tread wear or cupping over time
- Harder rubber compound can lead to reduced wet-weather grip during aggressive cornering
- Occasional reports of slow air pressure loss
Observations
- Users on lighter vehicles like older Jeeps noted improved comfort compared to more aggressive E-load rated tires.
- Heavy-duty truck owners reported mixed results, with some experiencing significant vibration and ride quality issues compared to lighter pickup applications.

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.
