Frequently Asked Questions
Q: What are the exact dimensions of SU 9111-A?
A: SU 9111-A is 6.000 inches in outside diameter and 2.750 inches in width. Bore depth is 0.83 inches with a bore outside diameter of 3.1491 inches. In metric: 152.40mm diameter by 69.85mm width. Tread profile features a 3/8 inch radius for optimal load distribution.
Q: Can I use SU 9111-A wheels on a truck that came with SU 9111?
A: Yes, SU 9111-A has the same bore and diameter specifications as SU 9111. They are direct mechanical replacements on the same trucks. The -A suffix designates assembly vs. wheel-only configuration. Verify the axle bore fits the 3.1491 inch outside diameter specification before installation.
Q: How do I diagnose if SU 9111-A wheels are worn out?
A: Spin each wheel by hand to check for grinding noise or resistance. Look for flat spots, cracks, or uneven tread wear across the wheel surface. If the wheel runs off-center, the bore is damaged. Measure tread depth at multiple points. Replace the wheel if tread is uneven, depth is less than 1/8 inch, or rotation is rough.
