Frequently Asked Questions
Q: Is SU 10 x 4 x 6.5-SF-R equivalent to Crown r01000400651 and Raymond r01000400651?
A: Yes. SU 10 x 4 x 6.5-SF-R is a direct OEM equivalent to both Crown r01000400651 and Raymond r01000400651. All three are solid rubber press-on drive tires with identical 10 inch outer diameter, 4 inch width, and 6.5 inch hub bore. The tread profile, hardness, and load capacity are the same. You can swap SU 10 x 4 x 6.5-SF-R as a replacement on Crown or Raymond trucks without modification. Always verify the truck model and serial range to confirm tire compatibility before ordering.
Q: What is the nominal load capacity of SU 10 x 4 x 6.5-SF-R at 24 inch load center?
A: The SU 10 x 4 x 6.5-SF-R carries a nominal 3500 lb capacity per drive wheel at 24 inch load center on Crown and Raymond models. This matches the OEM rating. Do not exceed the truck nameplate capacity because overloading rubber tires causes internal cracking and premature rim separation. Check your truck nameplate for exact capacity. Some heavy-duty models may be rated lower. Always verify before loading.
Q: How do you diagnose a failing SU 10 x 4 x 6.5-SF-R solid rubber tire?
A: Test for delamination by lifting the truck and spinning the wheel by hand. A healthy tire rotates freely and quietly. A failing tire may squeak, wobble, or feel loose on the hub. Visually inspect for cracks radiating from the hub bore or splits along the sidewall. Press your thumb into the tread: solid rubber does not rebound as much as polyurethane but should compress and hold shape. If the tread is hard as concrete or has hairline cracks, the rubber is deteriorating from age or UV exposure and the tire must be replaced. Check for stuck valves or rim damage as secondary causes.
Q: What is the installation procedure for pressing SU 10 x 4 x 6.5-SF-R onto a 6.5 inch hub?
A: Use a hydraulic press rated for 15 to 20 tons with bearing blocks that support the 6.5 inch hub bore. Clean the hub and tire bore with a brush to remove dirt and rust. Apply light silicone lubricant to the hub bore. Center the tire on the hub in the press and begin pressing slowly at 2 to 3 inches per minute. Watch for even seating around all sides. Stop when the tire sits flush. Do not exceed 25 tons because excessive force damages the hub bore. Solid rubber tires press more easily than polyurethane. Allow the assembly to cool for 1 hour before mounting on the truck.
Q: Does SU 10 x 4 x 6.5-SF-R leave marks on polished or sealed concrete floors?
A: Solid rubber tires are not non-marking. SU 10 x 4 x 6.5-SF-R may leave dark marks or scuffs on polished concrete or sealed epoxy floors, especially during sharp turns or if the floor is damp. Mark visibility depends on floor finish, humidity, and tire cleanliness. If your facility requires non-marking performance, upgrade to a polyurethane tire such as SU 10 X 4 X 6.5-SF-P. If you must use solid rubber, maintain a regular cleaning schedule and avoid dragging the truck.
Q: What is the service life and maintenance schedule for SU 10 x 4 x 6.5-SF-R rubber tires?
A: Solid rubber drive tires typically last 4 to 7 years depending on hours of operation and floor conditions. Inspect tread and sidewalls monthly for cracks or delamination. Clean tires biweekly with mild soap and water to remove oils and grit. Rotate drive and load wheels every 6 months to equalize wear. Check hub tightness monthly because loose tires slip on hubs and wear prematurely. Store unused replacement tires indoors at room temperature to prevent hardening from UV and heat. If a tire cracks or delaminiates, do not attempt repair. Remove it immediately to prevent rim damage and dangerous loss of control.
