Kumho Road Venture At52 Review

The Kumho Road Venture AT52 is the latest iteration in Kumho's all-terrain tire lineup, designed to bridge the gap between on-road comfort and off-road capability. Aimed at SUVs, light trucks, and crossovers, the AT52 promises a versatile performance profile for drivers who frequently encounter a mix of paved roads, gravel, and moderate off-road trails. In this detailed review, we'll dissect the AT52's construction, performance characteristics, and overall value proposition, catering to automotive enthusiasts, mechanics, and car owners seeking a well-rounded all-terrain tire.

Construction and Technology

The AT52's design prioritizes both durability and on-road refinement. Key to its construction is a robust internal structure featuring twin steel belts reinforced with a spirally wrapped nylon cap ply. This combination enhances tire strength, providing resistance to punctures and impacts encountered in off-road environments while also maintaining stability at highway speeds. The nylon cap ply minimizes tire deformation and promotes even wear, contributing to longer tire life.

The tire's sidewall is constructed with an enhanced shoulder design aimed at improving grip in soft terrains like mud and sand. The aggressive upper sidewall also provides additional protection against cuts and abrasions from rocks and other trail hazards. The overall sidewall construction provides robustness without sacrificing ride comfort.

The tread compound employed in the AT52 is a specially formulated blend optimized for all-weather performance. Kumho claims this compound enhances grip in wet and snowy conditions while maintaining acceptable wear characteristics. The compound's formulation also aims to minimize rolling resistance, contributing to better fuel economy compared to more aggressive all-terrain tires.

Tread Pattern and Features

The AT52 boasts an aggressive, yet strategically designed tread pattern. The pattern features wide grooves and multiple sipes, which are crucial for evacuating water, mud, and snow. The wide circumferential grooves channel water away from the tire's contact patch, reducing the risk of hydroplaning on wet roads. The high-density siping, small slits cut into the tread blocks, creates additional biting edges for improved traction on slippery surfaces, particularly ice and snow.

The AT52 features stepped shoulder blocks, which not only enhance the tire's aesthetic appeal but also contribute to its off-road performance. These blocks provide additional grip in loose dirt and gravel, helping the tire claw its way through challenging terrain. The alternating shoulder scoops further contribute to the tire's off-road prowess, aiding in self-cleaning and improved traction in muddy conditions.

Kumho has also incorporated stone ejectors within the tread pattern. These features are designed to dislodge small stones and debris that can become lodged in the grooves, preventing them from drilling into the tire carcass and causing damage. This extends the tire's lifespan and reduces the risk of punctures.

On-Road Performance

One of the key selling points of the AT52 is its ability to deliver a relatively comfortable and quiet ride on paved roads. While all-terrain tires are typically known for their noise and vibrations, Kumho has made significant efforts to minimize these drawbacks in the AT52. The optimized tread pattern and tread compound work together to reduce road noise and provide a smoother ride compared to more aggressive all-terrain options.

Handling and braking performance on dry pavement are commendable for an all-terrain tire. The AT52 provides decent steering response and stability, allowing for confident cornering and maneuvering. Braking distances are generally acceptable, although they may be slightly longer than those of dedicated highway tires. In wet conditions, the tire's siping and groove design provide adequate grip, but drivers should still exercise caution and reduce speed to maintain control.

Compared to dedicated highway tires, the AT52 will exhibit slightly increased rolling resistance, which can translate to a minor decrease in fuel economy. However, compared to more aggressive all-terrain tires, the AT52 offers a noticeable improvement in fuel efficiency. This makes it a suitable choice for drivers who prioritize fuel economy but still require off-road capability.

Off-Road Performance

The Kumho Road Venture AT52 is designed to handle a variety of off-road terrains, including gravel, dirt, sand, and moderate mud. Its aggressive tread pattern and robust construction provide sufficient grip and durability for most recreational off-road adventures. The tire's sidewall design offers enhanced protection against cuts and abrasions, allowing drivers to confidently navigate rocky trails.

In loose dirt and gravel, the AT52's stepped shoulder blocks and wide grooves provide excellent traction, enabling the vehicle to maintain momentum and control. The tire's self-cleaning properties help to prevent mud and debris from clogging the tread, ensuring consistent grip in challenging conditions. While the AT52 is not designed for extreme mudding or rock crawling, it can handle moderate mud and rocky trails with ease.

The tire's performance in sand is also noteworthy. The wide grooves and aggressive shoulder design help the tire to float over the sand, preventing it from digging in and getting stuck. However, drivers should still air down the tires to increase the contact patch and improve traction in soft sand conditions.

Ride Comfort and Noise

Kumho has prioritized ride comfort and noise reduction in the design of the AT52. The tire's optimized tread pattern and tread compound work together to minimize road noise and vibrations, providing a more pleasant driving experience. While some road noise is inevitable with an all-terrain tire, the AT52 is noticeably quieter than many of its competitors.

The tire's construction also contributes to its ride comfort. The reinforced sidewalls provide stability and support, while the flexible tread compound helps to absorb bumps and irregularities in the road surface. This results in a smoother and more comfortable ride, even on rough roads.

Warranty and Availability

The Kumho Road Venture AT52 typically comes with a limited treadwear warranty, which varies depending on the tire size and application. It's crucial to consult with your tire retailer or Kumho's official website for specific warranty details. The tire is available in a wide range of sizes to fit various SUVs, light trucks, and crossovers. Its availability is generally good through major tire retailers and online vendors.
