Kumho Road Venture AT KL78 Tire Review & Rating

The Kumho Road Venture AT KL78 has been developed to not only provide more than adequate off-road traction on a variety of terrains, but high performance street capabilities as well. Designed for drivers of pickups, SUV’s and Jeeps, the KL78 is the latest member of the Road Venture all-terrain lineup.

A cut and chip resistant tread compound is used on this tire along with asymmetric tread pattern. On-road dry traction performance is enhanced through the independent tread blocks, which also create added steering response and better overall feel when driven at higher speeds on the highway.

Kumho Road Venture AT KL78 Tire Review

The tire’s circumferential grooves, multiple lateral grooves and interlocking sipes increase wet pavement handling and add more biting edges in the snow, as well as off-road terrain. These grooves further reduce the risk of hydroplaning and improve braking performance. The KL78 addresses ride comfort and noise reduction by utilizing a variable pitch tread sequence in the block design.

Off-road, this Kumho tire is built to go through mud, gravel, sand, dirt, grass and other terrain, in addition to snow and ice. The tire’s optimized tread groove tapers around the tread to allow the tire to self-clean itself of mud, snow and dirt for enhanced loose surface grip.

Inside the tire you will find two high-tensile steel belts that are reinforced with nylon to provide added strength and durability throughout the speed range. They also increase stability and provide increased ride quality. Kumho also uses their unique ESCOT technology to ensure the best tire consistency possible. The Road Venture KL78 is available in 15-20 inch sizes, and in D and E load ranges for heavy-duty use.


  • Excellent dry and wet traction

  • Would like to see a little better tread life
  • Increase snow and ice performance

Overall Thoughts

Note: Kumho will be phasing out the KL78 and replacing it with the newly released Road Venture AT51. You can read our full review here.

While not excelling in any one particular area, the KL78 does provide very good all-around performance on and off road. Although it may not do any one thing particularly well, there are also no real glaring weaknesses at the same time.Traction on grass, gravel, sand, mud and light snow is really quite good. Steering response is average, as is the ride quality.

The only real problems for this model is a few complaints on a shorter treadlife. Tread wear has been an issue for some drivers in tire owner reviews. The other area is winter traction and handling. Although it gets you around, we’d like to see a boost in braking and acceleration in deep snow and on hard-pack or ice.

Overall, we rank this Kumho AT tire in the middle of the pack for tires in this class. The lower price over similar models from BFGoodrich, Goodyear and others, make it a pretty good value for the most part.
