Buyers Products Chock: Best for Chains

The Buyers Products Chock is a unique piece of gear that integrates a dedicated hole for securing with chains, providing an extra layer of security. On steep, icy hills where the potential for movement is high, tethering the chocks to the frame or a fixed ground anchor provides a safety net that standard chocks cannot match. This feature is a game-changer for those operating in mountain passes or extreme inclines.

While the chain-ready design is the primary draw, the rubber construction itself is high quality and capable of handling significant weight. The shape is optimized to fit flush against tire contours, minimizing the distance a tire can roll before making contact. It is a specialized tool, but it is one that offers peace of mind unmatched by non-tethered alternatives.

For the explorer who routinely parks on precarious, icy grades, the Buyers Products Chock is an essential upgrade. The ability to chain the chocks directly to the vehicle prevents them from sliding away if the tire starts to slip. This is the ultimate choice for those who prioritize fail-safe systems in their winter gear rotation.

Why Rubber Outperforms Plastic on Ice

Plastic chocks, while lightweight and cheap, are notoriously poor performers in cold temperatures. When plastic freezes, it becomes brittle and significantly loses its coefficient of friction, acting more like a slide than a brake on smooth ice. Rubber, by contrast, retains its natural pliability even in sub-zero conditions, allowing it to conform to the texture of the ground and the tire sidewall.

The weight difference also plays a crucial role in performance. Rubber chocks possess enough mass to bite into thin layers of ice, whereas lighter plastic models tend to float on top. This physical difference prevents the chock from skidding out of position when the weight of a vehicle is applied.

For any trip involving potential freezing conditions, abandoning plastic in favor of rubber is a mandatory safety upgrade. While the weight penalty is real, the trade-off in security is undeniable. Prioritizing rubber ensures that the vehicle stays where it is left, regardless of how slick the surface becomes.

Sizing Your Chocks for Winter Terrain

Sizing isn’t just about matching the tire diameter; it’s about matching the terrain’s volatility. On flat, hard-packed surfaces, a smaller chock suffices, but as the incline increases, the chock must possess more mass and a larger footprint to resist sliding. A good rule of thumb is to choose a chock that reaches at least one-third of the way up the tire’s sidewall for maximum stability.

Always consider the weight of the vehicle when choosing size. A heavy trailer on a slight incline will generate significantly more force than a light vehicle, requiring a wider, heavier chock to prevent structural shifting. Undersizing is the most common error in wheel chock selection, often leading to a false sense of security.

When in doubt, err on the side of a larger, heavier model. The minor inconvenience of hauling extra weight is far outweighed by the safety of knowing a heavy rig is properly anchored. Always check the manufacturer’s load rating to ensure the gear matches the specific weight class of the vehicle.

Proper Placement Methods on Icy Grades

Effective placement begins with “seating” the chock firmly against the tire before the vehicle settles. Simply tossing a chock near the tire is insufficient; push it under the tire to create a tight, uniform contact patch. On icy grades, it is critical to use two chocks per tire—one at the front and one at the back—to prevent any backward or forward creeping.

Always place chocks on the downhill side first to capture the vehicle’s momentum. If the grade is severe, clear any loose ice or snow from under the tire to allow the rubber to make direct contact with the ground. This preparation step is often the difference between a secure park and a dangerous slide.

Finally, ensure that the chocks are aligned perfectly perpendicular to the tire’s travel path. Any angle in the placement can lead to the tire slipping past the chock. Taking these extra seconds to seat the gear properly is the most effective way to maximize safety on challenging terrain.

Winter Care to Prevent Rubber Cracking

Rubber, while durable, is susceptible to degradation if exposed to extreme fluctuations in heat and cold without proper care. After a winter trip, clean any road salt, mud, or chemical de-icers from the rubber surface, as these substances can accelerate cracking and brittleness. A quick wipe-down with a damp cloth is usually sufficient to prolong the life of the material.

Store your chocks in a cool, dry place away from direct sunlight when they are not in use. Prolonged UV exposure can dry out the rubber compounds, leading to surface fissures that compromise the integrity of the chock over time. Maintaining a consistent storage environment keeps the material supple for the next adventure.

If cracks do begin to appear, inspect them regularly to ensure they aren’t deep enough to impact structural strength. While minor surface cracking is normal over the years, deep splits near the base can indicate it is time to replace the gear. Treating your chocks with the same care as your tires will ensure they provide reliable service for many years.

Properly securing a vehicle on icy, unpredictable terrain is a fundamental skill for any outdoor enthusiast. By selecting the right rubberized chocks and utilizing correct placement techniques, you turn a potential hazard into a non-issue. Whether you are navigating a mountain trailhead or a snowy campsite, gear up correctly, park with confidence, and enjoy the freedom of the outdoors.
