SU 10 X 4 X 6.5-R-DIAMOND

Frequently Asked Questions

Q: What is the purpose of the diamond tread pattern on SU 10 X 4 X 65-R-DIAMOND?
A: The diamond tread provides increased traction and grip on wet, oily, or uneven warehouse floors compared to smooth tread tires. The raised diamond pattern channels liquids away from the contact surface and improves steering response during turns. SU 10 X 4 X 65-R-DIAMOND is recommended for applications with frequent outdoor use or damp conditions. Diamond tread does produce light marking on polished floors, so confirm your facility allows textured tires before purchase.

Q: Is SU 10 X 4 X 65-R-DIAMOND compatible with Crown and Raymond lift trucks?
A: Yes. The 10 inch diameter, 4 inch width, and 6.5 inch hub bore match Crown and Raymond OEM specifications. However, no direct OEM part number cross-reference is available for this SKU. Before installation, verify your specific truck model can accept a diamond-tread rubber tire. Some fleet applications standardize on smooth tread for marking control. Contact Crown or Raymond with your truck serial number to confirm compatibility.

Q: What load capacity does SU 10 X 4 X 65-R-DIAMOND carry per wheel?
A: The SU 10 X 4 X 65-R-DIAMOND is rated for the same nominal 3500 to 4000 lb capacity per drive wheel at 24 inch load center as standard 10 x 4 x 6.5 tires. Load rating depends on the truck model. Always check your truck nameplate capacity before operation. Overloading causes internal cracking in the rubber and premature failure. The steel-reinforced core helps carry load but cannot compensate for sustained overweight operation.

Q: How do you detect when SU 10 X 4 X 65-R-DIAMOND needs replacement?
A: Inspect the diamond tread pattern every month. If the diamonds wear flat or smooth, traction decreases significantly and the tire should be replaced. Look for cracks radiating from the hub bore or along the sidewall, which indicate rubber deterioration. Perform a spin test: lift the truck and rotate the wheel by hand. Listen for squeaks or grinding sounds. Check hub tightness because a loose tire spins inside the bore and accelerates failure. If cracks or loose fitting occur, replace the tire immediately. Typical service life is 4 to 6 years.

Q: What is the correct procedure for pressing SU 10 X 4 X 65-R-DIAMOND onto a 6.5 inch hub?
A: Use a hydraulic press rated for 15 to 20 tons with bearing blocks sized for the 6.5 inch bore. Clean the hub bore and tire bore with a wire brush to remove rust and debris. Apply silicone lubricant lightly to the hub bore for easier installation. Position the tire vertically in the press with the hub centered. Press slowly at 2 to 3 inches per minute until the tire seats fully. Stop when the tire is flush with the hub. Do not exceed 25 tons of force. Allow 1 to 2 hours for the rubber to set before mounting the wheel on the truck.

Q: How should SU 10 X 4 X 65-R-DIAMOND rubber tires be maintained and stored?
A: Clean tires weekly with mild soap and water to remove debris and oils that promote cracking. Rotate drive and load wheel sets every 6 months to equalize wear. Inspect tread and sidewalls every 30 days for cracks or delamination. Check hub bore tightness monthly and repress if the tire moves on the hub. Store unused tires indoors at room temperature away from sunlight and heat, which harden rubber and reduce tread elasticity. Keep tires away from oils, solvents, and ozone sources. Replace tires showing cracks or missing diamond tread sections immediately.
