Frequently Asked Questions
Q: What is the difference between SU 9812-EZ and SU 9812-EZ-A?
A: Both the SU 9812-EZ and SU 9812-EZ-A are 3.25 x 6.01 inch Cushothane XL load wheels with identical dimensional specifications. The EZ-A designation may indicate a variant assembly or packaging option. Cross-reference your parts manual or contact the supplier to confirm interchangeability on your specific truck model.
Q: Is the SU 9812-EZ-A a direct replacement for the SU 9812-EZ?
A: The SU 9812-EZ-A appears to be a direct replacement with the same 3.25 x 6.01 specifications and Cushothane XL material. However, verify the bore diameter (2.0467 inch) and hub width (6.01 inch) match your existing axle assembly. If you are uncertain, test fit on your truck before full installation or consult the truck manufacturer.
Q: What does the A variant designation mean for the SU 9812-EZ-A wheel?
A: The A suffix on industrial wheels often indicates an alternate material grade, packaging style, or assembly configuration. For the SU 9812-EZ-A, both models use Cushothane XL, so the A likely designates a different assembly method or supply channel. Check your truck manual or OEM documentation for the correct part number for your machine.
Q: Can I mix SU 9812-EZ and SU 9812-EZ-A wheels on the same truck?
A: Avoid mixing wheel variants on the same axle or truck if possible. Even slight material or wear pattern differences can cause uneven weight distribution and steering issues. If you must use both, ensure all four wheels have identical tread wear depth and material hardness to maintain stable operation.
Q: What tools and safety precautions do I need to install the SU 9812-EZ-A?
A: You will need a tire jack or truck lift, socket set, axle pin puller, and safety blocks. Ensure the truck is on a level surface and locked in place. Wear steel-toed boots and work gloves. Never work beneath a truck supported only by a hydraulic jack; always use secure blocks. Allow wheels to cool if the truck has been in operation.
