Frequently Asked Questions
Q: What does the XL designation mean on the SU 2400-XL load wheel?
A: XL indicates an extra-large diameter or wider tread load wheel compared to the standard SU 2400. Larger wheels reduce rolling resistance and improve maneuverability on rough or uneven warehouse floors. XL wheels also lower the effective gear ratio, reducing stress on the truck motor during extended operation. Confirm your truck clearance allows the larger diameter before purchasing.
Q: Can I mix and match SU 2400 standard and SU 2400-XL wheels on the same truck?
A: No. Mixing wheel sizes creates mismatched steering geometry and will cause erratic handling, uneven tire wear, and possible damage to the steering mechanism. All four wheels must be the same size and type. If upgrading to SU 2400-XL, replace all load wheels as a complete set.
Q: Does the SU 2400-XL require different bearing specifications than the standard SU 2400?
A: The SU 2400-XL likely uses the same bearing size and type as the standard SU 2400 but may have a larger diameter core to accommodate the increased wheel diameter. Do not assume bolt-on compatibility without measuring the core bore and comparing axle specifications. Request the detailed dimension sheet from your supplier before ordering.
Q: What symptoms indicate an SU 2400-XL wheel needs replacement?
A: Replace the SU 2400-XL if you observe flat spots or chunking in the tread, audible squeaking or grinding when the wheel rotates, visible cracks in the polyurethane, or noticeable wobbling or side-to-side play. A properly functioning wheel should spin freely for 5-10 complete rotations when rotated by hand. If it stops after 1-2 rotations, the bearing is likely seized.
Q: Will upgrading to SU 2400-XL wheels improve my truck battery runtime?
A: Yes, slightly. Larger wheels reduce rolling resistance and mean the motor draws less current during horizontal movement. You may see a 5-10 percent increase in runtime depending on floor conditions. However, this benefit is most noticeable on rough floors. On smooth concrete, the improvement is negligible. Larger wheels also reduce noise and vibration, which are secondary benefits.
