RC Repair Tools & Parts: Choose the Right Crawler Tires or Hex Kit

Quick take

The key decision is whether you need replacement rubber for an RC crawler or hand tools for assembly and repairs. The three tire sets differ mainly by wheel format, dimensions, and stated fit references, while the Arrarown kit is meant for tightening, loosening, and assembling across several RC types. Start with the component your vehicle or workbench actually needs, then use the listed measurements and compatibility details to narrow the choice. The four prices have an absolute spread of $15.26, but fit should come before price when comparing tires.

Decision matrix

• Replacing crawler tires: Compare the three tire sets by wheel format first. Then use outside diameter, width, inner diameter, and named vehicle references to separate the choices.
• Choosing for terrain language: The HOBBYSOUL set specifically describes use on mud, loose dirt, and slick rock. That makes its stated terrain focus a useful tie-breaker when its wheel format matches the build.
• Building a repair bench: Choose the Arrarown kit when drivers, sockets, and screwdrivers matter more than replacement rubber.
• Comparing similar tire formats: Do not rely on a shared wheel-size label alone; the complete measurements can point to different fit requirements.

Product notes

BFGoodrich Mud-Terrain Crawler Tire Set

This four-piece set is a tire-first choice for a 1:10 crawler using 1.9-inch wheels. It carries the BFGoodrich Mud-Terrain T/A name and gives a 90mm outside diameter, with fit references for Axial SCX10 ii 90046 and Traxxas TRX4. Choose it when those vehicle references and the 90mm measurement line up with the build you are repairing. The limitation is packaging: the tires are out of their original packaging, although they are unused. That detail matters if presentation or original packaging is part of your purchase decision.

HOBBYSOUL Griptrek Crawler Tire Set

The HOBBYSOUL set is aimed at a build calling for 1.3-inch beadlock wheels. It includes four 72mm-tall, 28mm-wide Griptrek tires and specifies a soft, sticky compound with asymmetric, irregular triangular tread for mud, loose dirt, and slick rock. That wheel fit and stated terrain focus are the clearest reasons to choose it. Its limitation is fit specificity: the set is intended around 1.3-inch beadlock wheels, so it is not a like-for-like choice with the 1.9-inch tire sets. It also has the highest listed price in the comparison, making wheel format and intended terrain more important than price alone.

Rubber 1.9-inch Crawler Tire Set

This four-piece rubber tire set suits a 1:10 crawler using 1.9-inch tires and gives a complete dimensional reference: 120mm height, 50mm width, and 48mm inner diameter. It names Axial SCX10 ii 90046 and Traxxas TRX4 among its fit references, giving shoppers concrete vehicle details to compare against their build. Choose it when those measurements are the ones your replacement calls for. The limitation is that it remains a tire-only purchase; it does not add tools, sockets, or other repair hardware. Its measurements also provide a different sizing reference from the other 1.9-inch set, so use the full dimensions rather than the shared wheel label alone.

Arrarown RC Repair Tools Kit

The Arrarown kit is the practical choice when the job is broader than replacing tires. It includes a handle, hex bits at 1.5, 2.0, 2.5, and 3.0mm, 4.0 and 5.5mm hex nut sockets, 0#+ Phillips and 1#- slotted screwdriver bits, plus a red tray for screws and small parts. Its stated repair coverage includes RC cars, drones, helicopters, airplanes, boats, robots, and several model families. Choose it for a mixed repair and assembly bench. The limitation is category-specific: it supplies hand tools, not crawler tires or other replacement parts.

Final recommendation by use case

• For the lowest listed price among the tire sets: Choose the BFGoodrich Mud-Terrain Crawler Tire Set at USD 21.00 when the 1:10, 1.9-inch fit references and 90mm outside diameter suit your build.
• For the tire set specified at 120mm high, 50mm wide, and 48mm inner diameter: Choose the Rubber 1.9-inch Crawler Tire Set, provided those measurements match the replacement you need.
• For 1.3-inch beadlock wheels and the stated mud, loose-dirt, and slick-rock focus: Choose the HOBBYSOUL Griptrek Crawler Tire Set.
• For assembly and repairs across multiple RC types: Choose the Arrarown RC Repair Tools Kit for its combination of hex, socket, Phillips, and slotted drivers.

Match wheel format and complete measurements before treating price as the deciding factor. If the job is tool-focused rather than tire-focused, the Arrarown kit is the clear category match.
