Steel-hub version of JSumo's 33mm silicone wheel. Same tire, same footprint as the aluminum SLT20, but a steel hub for more rigidity and wear resistance under repeated hard stalls — a common upgrade path once a builder's motors are running at 3S/4S and stalling hard against the tape line.
| Diameter | 33mm |
| Width | 20mm |
| Hub material | Machined steel |
| Weight | 52g per wheel |
| Center bore | 3mm |
| Mounting | M4 tapped setscrew (included) |
| Fits gearmotor diameter | 12mm, 15mm, or 16mm body |
Included: 2× wheels, 2× M4 setscrews, 1× Allen key.
Weight note: the steel hub adds roughly 30g per wheel over the aluminum SLT20 — worth weighing against your 500g budget, since weight on the drive axle helps traction but weight anywhere else is dead weight.
Works with:
- Motors (3mm D-shaft, direct fit): Core DC 400 RPM, Core DC 750 RPM, and any mini sumo gearmotor with a 3mm D-shaft
- Spare tires: SLT20 Replacement Silicone Tire Pair — refresh grip without replacing hubs
- Aluminum-hub version: SLT20 Aluminum Wheel Pair (~30g lighter per wheel)
