Wheel Chocks for Cars, RVs, Trucks, Trailers, and Vehicles G.V.W. up to 6T, 2 Pack - Anti Slip Bottom Tire Chock for All Weather Use - RV, Travel Trailer, Pop Up Camper Accessory

I chose these wheel chocks because they were made of rubber and the base was ribbed to grab onto the pavement. I had some plastic ones that would move every time the trailer, either my travel trailer or utility would rock. They are heavier than the plastic and, unlike the plastic, will not nest together but I needed to have stability vs light weight.

These are made of lightweight plastic, but still seem indestructible. Brightly colored so you don’t lose them in diminished light. Compact lightweight and effective wheel stops.

Spend the money on good ones like these and not the cheap plastic ones. I feel it's worth everyone's safety by doing so.

These work great. Hold my 18’ boat on an incline perfectly fine.

These solid rubber chocks are so much better than the cheap plastic ones that Wally World and other big box retailers sell. The textured bases grip gravel and dirt really well, and the rubber itself is sticky enough to also be secure on asphalt, concrete and smooth garage floors. Well worth the added weight.These are physically smaller than the hollow plastic ones, but so far I have had no issues with these slipping when used with either car/truck wheels or a travel trailer with 15" off road wheels.

They are rubber and have been working fine for a first time camper owner.

Works great for us!

Very nice heavy weight wheel chocks for a trailer tire. The medium size hugs a 205/75R15 tire PERFECTLY and are infinitely better than the cheap hollow plastic chocks. They grip the ground well, even on a smooth concrete garage floor.
