Quick Answer
The Incision Method 1.9 MR307 wheel fits most stock RC crawler axles with its included #4 Incision hub, but you should verify your axle stub diameter and wheel hex size before purchasing.
Why Fitment Matters for the MR307
The Incision Method 1.9 MR307 uses an internal clamp ring beadlock system with a 0.8-inch wide mounting surface (1.0 inch to the outside of the wheel). This design keeps the wheel lightweight and strong, but the narrower mounting surface means tire selection and hub compatibility are more critical than with wider aftermarket wheels. Always check your axle's hex size and stub length to ensure the included #4 hub fits securely.
Frequently Asked Questions
Will the MR307 fit my Traxxas TRX-4 or Axial SCX10?
Yes, in most cases. The included #4 Incision hub fits standard 12mm hex axles found on the TRX-4 and SCX10. If your axle uses a different hex size or has a longer stub, you may need a different hub (sold separately).
What tires work with the 0.8-inch mounting surface?
Look for 1.9 tires with a bead width around 0.8 inches. Narrower tires seat properly on the internal clamp ring. Wide tires may bulge or fail to seal. Measure your tire's inner bead width before mounting. Check tire bead width against the 0.8-inch mounting surface.
How do I mount tires on the MR307 beadlock?
Remove the 5 screws on the outer ring, place the tire bead over the inner ring, then press the outer ring back on and tighten the screws in a star pattern. The internal clamp ring design allows rapid tire changes without disassembling the entire wheel. Use a star pattern to avoid warping the ring.
Can I use the MR307 on a custom or scale build?
Yes, the officially licensed Method Race Wheel design adds scale realism. The 1.0-inch overall width fits most scale chassis without rubbing. Verify your suspension and steering links clear the wheel at full turn. Test fit at full steering lock before final assembly.
What hardware is included?
Grade 5 Stainless Steel hardware is included for the 5 beadlock screws and the hub mounting screws. This resists corrosion better than standard steel hardware.
