For single rear wheel flatbed trucks, the Ultimate Flap 12-by-30-inch weighted pair is best for buyers who want pre-installed weights and broad coverage, while the non-weighted version suits those who prefer a lighter flap. Other options include a compact rubber pair, a heavy-duty polymer set, and general-purpose rubber flaps. Check flap dimensions and mounting points against your truck before choosing; “universal” does not confirm fit for every setup.

| Ultimate Flap Non-Weighted | Lightweight flatbed setup | 12 × 30 inches |

Ultimate Flap Weighted 12 × 30-Inch Mud Flaps
Best for: Single rear wheel flatbed owners who want extended coverage with added flap stability. These 12-by-30-inch guards have pre-installed stainless steel weights intended to help prevent lifting at higher driving speeds. The listing describes them as a universal flatbed fit for single rear wheel trucks and custom setups, and says they are pre-drilled for easier installation.
Choose this pair if you want a weighted design and large coverage for mud, rocks, and road debris, including when towing or running oversized tires. The pre-drilled holes may simplify mounting, but the listing does not specify vehicle-specific hardware or fitment. Verify that the flap dimensions and hole locations suit your flatbed before buying.
Ultimate Flap Non-Weighted 12 × 30-Inch Pair
Best for: Single rear wheel truck owners who want tall flatbed coverage without added weights. The 12-by-30-inch design is described as suitable for flatbeds and single rear wheel setups. Its non-weighted construction is presented as lightweight and easy to handle, and the pair is pre-drilled.
This is the better choice if you value simpler handling over a weighted design and need protection from water spray, mud, rocks, and road debris. Compared with the weighted Ultimate Flap option, it does not have pre-installed stainless steel weights. Check clearance and mounting points to confirm the extra height works with your specific truck.
Buyers Products 24 × 30-Inch Polymer Mud Flaps
Best for: Buyers who need broad coverage and a polymer material described as impact-resistant. This two-pack measures 24 by 30 inches and uses 3/16-inch black polymer. The product information says the flaps help deflect stones, mud, spray, and road debris, and are designed to remain durable in subfreezing conditions while resisting snow and ice buildup.
Choose this set if coverage area and cold-weather use matter more than a specifically listed single-wheel flatbed design. The listing describes universal-fit use on compatible trucks, semitrucks, and trailers, but does not identify particular flatbed mounting points. Its large dimensions may not suit every setup, so measure available space before ordering.
12 × 18-Inch Rubber Mud Flaps
Best for: Buyers looking for a simpler, more compact rubber option. The listed product is a pair of 12-by-18-inch mud flaps, with a stated width of 12 inches and rubber construction. That makes the dimensions and material clear, but the product details do not describe weighted edges, pre-drilled holes, or flatbed-specific compatibility.
Consider this pair if its size matches your mounting area and you prefer rubber. It may be less suitable if you need the 30-inch-tall coverage specifically offered by the flatbed-focused Ultimate Flap products. Confirm the full dimensions and installation requirements with the product listing before purchase.
XUKEY 15 × 12-Inch Heavy-Duty Rubber Flaps
Best for: Buyers seeking a general-purpose rubber pair with stated dimensions. The listing gives a size of 15 inches long by 12 inches wide and a thickness of 4 mm. It describes the material as heavy-duty rubber and lists a range of vehicle types, including light trucks, RVs, and vans.
This option may work when those dimensions suit a flatbed mounting location, but it is not specifically described as a single rear wheel flatbed set. The listed vehicle examples do not establish fitment for every truck. Choose it only after checking its size and installation method against your setup.
Buying Guide: How to Choose Single Wheel Flatbed Mud Flaps
What size mud flaps should you choose?
Start by measuring the available mounting area and checking the intended coverage behind the tire. The products here range from 12-by-18-inch flaps to 12-by-30-inch and 24-by-30-inch options. Larger guards can cover a broader area, but they also need sufficient clearance and suitable mounting space. Do not assume that a universal label means every size fits your truck.
Should you choose weighted or non-weighted flaps?
Weighted flaps are a practical option if you want added stability. The Ultimate Flap weighted pair has pre-installed stainless steel weights, which the listing says help prevent lifting at high speeds. The non-weighted pair is described as lightweight and easier to handle. Choose based on your preference and installation requirements; the non-weighted design does not include the listed stainless steel weights.
Which material and coverage matter most?
Rubber is used in the compact 12-by-18-inch pair and the XUKEY option. Buyers Products uses 3/16-inch polymer and specifically describes impact resistance and cold-weather durability. Compare the material claims with your expected driving conditions, then confirm dimensions, mounting holes, and clearance. A broad flap is not automatically the best fit if it interferes with the truck or trailer setup.
Frequently Asked Questions
Are these mud flaps specifically made for single rear wheel flatbeds?
The two Ultimate Flap products are explicitly described for flatbeds and single rear wheel setups. The other listings describe broader vehicle uses or provide limited fitment details.

Are pre-drilled mud flaps guaranteed to fit my truck?
No. Pre-drilled holes can help with installation, but the listing does not establish that the hole pattern matches every truck. Check mounting locations before purchase.
Which option has the largest listed dimensions?
The Buyers Products pair is listed at 24 by 30 inches. Confirm available mounting space and clearance before selecting it.
Do these products include mounting hardware?
