Frequently Asked Questions
Q: What is the correct bolt hole size for SU 15x8x11.25-SF-P installation?
A: SU 15x8x11.25-SF-P mounts on an 11.25 inch bolt circle hub. This is different from other press-on wheels with 11.75 inch circles. Installing on the wrong hub size will cause wobble, misalignment, and potential wheel separation under load. Always verify hub diameter before purchase and installation.
Q: Can I replace a 15x6 wheel with SU 15x8x11.25-SF-P on the same jack?
A: No. The 15x8 is wider than 15x6 and may contact fork arms, carriage brackets, or steering linkage on your jack. The wider wheel also changes the load distribution and effective leverage. Always use the exact width and diameter specified on your jack nameplate.
Q: Why would someone choose a 15x8 wheel instead of 15x6?
A: The wider 8 inch profile distributes load over a larger footprint, reducing point stress on the floor. Use 15x8 on rough or damaged concrete, uneven surfaces, or when carrying heavy side loads. The trade-off is slightly increased rolling resistance and steering effort.
Q: What does smooth flat profile mean on SU 15x8x11.25-SF-P?
A: Smooth flat tread has no traction pattern or grooves. It is designed for smooth, clean warehouse floors and provides low rolling resistance and good visibility when the jack is stopped. Do not use smooth-tread wheels on oily, wet, or textured floors, where the jack will slip and become unstable.
Q: How do I install SU 15x8x11.25-SF-P press-on wheels?
A: Press-on wheels slip over the hub without bolts. Place the wheel on the hub and apply steady downward pressure by hand or a press. Do not hammer or force the wheel. If resistance is high, clean the hub and wheel bore with a dry cloth. The wheel should slide on smoothly and sit flush against the hub face. Verify it does not wobble before operating.
Q: What maintenance does SU 15x8x11.25-SF-P polyurethane wheel need?
A: Inspect for cracks, flat spots, or chunks missing from the tread every 30 days. Clean debris and dirt from the wheel. Check the bearing or axle grease level per the jack manual. Do not apply water, oil, or solvents to the wheel. Replace when permanent deformation appears or the wheel loses shape.
