If you want reliable protection for a 2" x 2" square receiver tube that resists rust and corrosion, choose CURT 22272; if you need heavy-duty tire chocks with non-slip traction pads to prevent rollaway on slopes or driveways, choose MAXXHAUL Solid Rubber Wheel. These two items serve entirely different purposes in the realm of vehicle maintenance, yet both are essential for keeping your rig secure when parked or not in use. One is designed to seal off a hitch opening from the elements, while the other acts as a physical barrier against gravity and movement. Understanding the specific utility of each prevents the common mistake of buying a wheel chock when you actually need a hitch cover, or vice versa.
• CURT 22272: Its biggest strength is the friction-fit design that requires no pins or clips for quick installation on Class 3, 4, or 5 hitches; its trade-off is it only fits 2" x 2" square receivers and offers no security against theft without an additional lock.
• MAXXHAUL Solid Rubber Wheel: Its biggest strength is the molded high-friction surface that grips pavement and gravel to stop tires from rolling, even on steep inclines; its trade-off is that it is sold as a pair, which might be overkill for single-tire needs or tight storage spaces.
• Who it's for: The CURT 22272 is for owners of Class 3–5 hitches who want a simple, rust-proof shield for their receiver tube.
• Who it's for: The MAXXHAUL Solid Rubber Wheel is for anyone parking on uneven ground, snowy driveways, or job sites who needs to ensure their vehicle stays stationary.
The CURT 22272 is a straightforward solution for protecting the open end of a trailer hitch. When you tow a load or drive a truck with a hitch installed, the large square opening is exposed to everything the road throws at it. Dirt, water, debris, and road grime can easily find their way inside the receiver tube. Over time, this accumulation leads to rust and corrosion, which can make future towing setups difficult or impossible to remove. This black rubber cover is specifically engineered to block those elements out completely.
Constructed from durable black rubber, this item does not rely on metal components that could rust or degrade. The material is chosen for its ability to withstand rain, snow, mud, and normal outdoor towing conditions without losing its shape or integrity. It is a passive defense mechanism that sits quietly behind your bumper, doing its job silently until you need to pull it out again. The design is minimalistic but effective, focusing entirely on sealing the void left by the hitch ball mount.
Installation is where this product shines for the casual user. Because it uses a friction-fit design, you do not need to hunt down a hitch pin, clip, or any additional hardware to keep it in place. You simply push the cover directly into the receiver tube, and it stays there securely. This makes it ideal for drivers who want a "grab-and-go" solution that takes seconds to install or remove. However, you must verify that your receiver is exactly 2" x 2" square before ordering, as it will not fit rectangular or other size openings. If you have a standard Class 3, 4, or 5 hitch, this is likely the perfect fit.

While the CURT piece protects the back of your truck, the MAXXHAUL Solid Rubber Wheel addresses the safety of the entire vehicle when it is stationary. This product is a pair of heavy-duty tire stops designed to prevent accidental rollaways. Whether you are parked on a driveway with a slight grade, a campsite on uneven terrain, or a job site with loose gravel, these chocks provide a critical layer of security. They are built to handle significant weight without crushing or deforming, making them suitable for cars, trucks, trailers, and RVs alike.
The construction here is all about stability and grip. Made from premium-grade molded rubber, these chocks resist cracking, crushing, and deformation under the weight of a vehicle. Unlike plastic alternatives that might shatter in cold weather or melt in heat, this solid rubber formulation remains stable across all seasons. It is also oil-resistant, meaning it performs reliably even if placed on surfaces with residual oil or grease, which is common in garages and industrial areas. The material choice ensures that the chock maintains its structural integrity year after year.
One of the most practical features is the integrated molded handle. You can pick up, reposition, and remove the chocks quickly without needing tools or fiddling with metal rings that can pinch your fingers. The dimensions of roughly 8" x 4" x 6" make them space-efficient enough to store inside a compartment or leave behind a tire without taking up too much room. The non-slip traction pads on the bottom are crucial; they grip the pavement, gravel, or garage floor firmly to reduce the risk of the chock sliding away when the tire hits it. This makes it an indispensable tool for tire maintenance and general vehicle safety.
• Best for Receiver Protection → CURT 22272: If your primary concern is keeping dirt, water, and grime out of a 2" x 2" square hitch receiver, this is the only logical choice.
• Best for Rollaway Prevention → MAXXHAUL Solid Rubber Wheel: If you need to physically stop a vehicle from moving on a slope or slippery surface, the chocks are the necessary equipment.
• Best for Simple Installation → CURT 22272: Requires zero hardware; just push it in. No pins, clips, or bolts needed.
• Best for Heavy-Duty Traction → MAXXHAUL Solid Rubber Wheel: Features molded high-friction surfaces designed to grip gravel, pavement, and oily floors better than smooth rubber.
• Best for Weather Resistance → Both: Both utilize rubber compounds that resist rain, snow, UV exposure, and corrosion, though the chocks are explicitly rated for oil resistance as well.
• Best for Storage Portability → MAXXHAUL Solid Rubber Wheel: The built-in handle makes carrying the pair easy, whereas the hitch cover is small but lacks a dedicated carry feature.
• Best for Class 3/4/5 Hitches → CURT 22272: Specifically sized for standard 2" x 2" square tubes found on these hitch classes.
• Best for Multi-Vehicle Use → MAXXHAUL Solid Rubber Wheel: Sold as a pair, making it ready for immediate use on multiple vehicles or one large vehicle requiring two points of contact.
In my opinion, you should buy the MAXXHAUL Solid Rubber Wheel if your priority is preventing accidents and ensuring your vehicle stays put during tire maintenance or long-term parking. The physics of a rolling vehicle demand a physical barrier, and the non-slip traction pads on these chocks offer a level of safety that a hitch cover simply cannot provide. While the CURT 22272 is an excellent, low-maintenance accessory for protecting your hitch from rust, it serves a niche function that only applies to the rear receiver of your tow vehicle. For the broader goal of vehicle safety and stability, especially when dealing with slopes or slick surfaces, the MAXXHAUL chocks are the superior investment. They address a more immediate safety hazard with robust, all-weather durability.
