OULEME Heavy-Duty Rubber Wheel Chocks for RVs & Trailers — 4-Pack, UV-Resistant 8.5×4×6

These wheel chocks are molded from reinforced rubber and shaped to resist slipping, cracking, and UV damage so your vehicle stays stationary on driveways, campsites, or inclined surfaces. Each chock measures 8.5" x 4" x 6" and weighs 4 lb, giving a low-profile but substantial contact area that distributes force and improves hold compared with lightweight plastic alternatives. Sold as a set of four, they suit a wide array of vehicles including RVs, travel trailers, boats on trailers, and light- to medium-duty trucks.

How do these chocks stop vehicles on slopes or uneven ground?

The OULEME chocks use a triangular stabilizing geometry and a double-sided textured surface to create friction between tire and chock. Their weight and rubber composition absorb vibration and limit roll-back when parked on modest inclines. Use two per wheel or pair them front-and-back for added redundancy.

• Triangular shape spreads load and reduces slippage.
• Double-sided anti-slip treads grip tire rubber and ground.
• 4 lb mass resists movement from small bumps or wind.
• Works on asphalt, gravel, compacted dirt and concrete.

Are these chocks tough enough for long-term outdoor exposure?

Yes. The chocks are manufactured from upgraded rubber compounds formulated to resist UV breakdown and common weathering, so they remain flexible rather than brittle over time. That weatherproofing helps preserve the gripping surface and overall integrity even when left outdoors between trips.

• UV-resistant rubber prevents cracking in sunlight.
• Weatherproof formulation tolerates rain and temperature swings.
• Durable construction for repeated use and transport.
• No need for frequent replacement like thin plastic chocks.

What vehicle types and tire sizes are compatible with these chocks?

Designed as a universal-size solution, each 8.5" x 4" x 6" chock accommodates many passenger and light-commercial tire profiles commonly found on RVs, trailers and pickup trucks. They are well-suited for mid-size and larger tires; for unusually narrow or oversized industrial tires, verify fit before use.

• Fits most RVs, travel trailers, and boat trailers.
• Appropriate for light- and medium-duty trucks and vans.
• Works with common tire treads and rounded sidewalls.
• Sold in a 4-pack for multi-wheel coverage.

How should I place and store these chocks for best performance?

Position a chock against the tire tread on the downhill side and press firmly to seat it before engaging parking brakes. For extra security, place a second chock opposite the first or behind the tire. Store chocks off the ground in a shaded area or vehicle storage compartment to extend their service life when not in use.

• Use one chock per wheel or pairs front/back for added safety.
• Place downhill of the tire; avoid resting on loose debris.
• Keep in a dry, shaded compartment when storing long-term.
• Inspect treads occasionally for deep cuts or wear.
