Slide each adapter onto the motor shaft, positioning it flush against the motor housing to minimize overhang and reduce bending moment stresses. Tighten both set-screws in a cross-pattern using a 1.5mm hex key, applying 0.5 Newton-meters of torque to prevent shaft damage while ensuring zero rotational play. Test rotation by hand to confirm smooth operation without grinding sounds indicating misalignment.\u003c\/p\u003e\n\n\u003cp\u003eMount each wheel assembly onto the adapter using the integrated mounting interface, ensuring the wheel sits perpendicular to the motor shaft within 2 degrees of tolerance. For pneumatic tires, check air pressure using a precision gauge calibrated to 0.5 PSI accuracy, maintaining 25-30 PSI for optimal performance. Higher pressures reduce rolling resistance but decrease traction, while lower pressures improve grip but increase heat generation and tire wear. Perform a test run at 50% motor power to verify both wheels rotate in the intended direction and maintain equal speed, confirming drivetrain balance before full-power operation.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the maximum recommended payload for these wheels?\u003c\/summary\u003e\n\u003cp\u003eEach wheel can support 25kg of static load without deformation. During dynamic acceleration events, wheels can handle peak loads reaching 50kg for brief periods. For a four-wheel platform, maximum recommended total payload is 80-100kg depending on weight distribution and acceleration profiles. Exceeding these limits causes permanent tire deformation and reduces grip characteristics.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eAre these wheels compatible with my specific motor shaft?\u003c\/summary\u003e\n\u003cp\u003eThe 4mm adapters fit motor shafts with 4mm diameter specifications. Verify your motor shaft diameter using precision calipers before purchase. Common compatible motors include Pololu micro metal gearmotors, TT motors with 4mm shafts, and equivalent third-party systems. If your shaft diameter differs, contact our technical team for alternative adapter recommendations.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eHow do I maintain optimal tire pressure and what pressure should I use?\u003c\/summary\u003e\n\u003cp\u003eCheck tire pressure weekly using a precision gauge accurate to 0.5 PSI. Maintain 25-30 PSI for balanced performance between traction and rolling resistance. For sandy terrain, reduce pressure to 20 PSI to increase contact patch. For hard surfaces like concrete, increase to 32 PSI to reduce rolling resistance. Never exceed 35 PSI as this causes uneven wear and reduces grip on uneven surfaces.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eCan these wheels handle indoor and outdoor use?\u003c\/summary\u003e\n\u003cp\u003eYes, these wheels perform excellently in both environments. The aggressive tread pattern provides superior grip on outdoor terrain including grass, gravel, and sand. Indoors, the pneumatic construction absorbs vibration from hard floors while maintaining traction on polished concrete and tile surfaces.
