Buyer applications
A depot bus, highway trailer and yard vehicle can share a nominal wheel size and still need different mounting, clearance and load evidence.
Send axle position, piloting method, PCD and load rating. For dual fitment, verify the tire spacing on the chosen rim width and offset before approving either the tire or the wheel. When comparing steel and alloy options, request measured wheel mass in kg for the same load rating and confirm the fastener seat and corrosion protection on each drawing.
Map sizes by axle and order frequency. Compare supplier pack quantities with the customer’s replacement demand. Stock can simplify reorders where the same drawing and finish remain available. A custom revision may resolve brake clearance or coating requirements and adds tooling and sample approval to the comparison.
Describe duty cycle, inflation conditions and exposure to mud or chemicals. For split rim wheels, ask the supplier to match rim base and ring markings to its component chart and send its service instructions. For sample inspection, have the supplier specify the runout datum and check radial and lateral readings separately against the drawing’s tolerances. Record the rim marking and revision with the readings.
Include load, surface, axle location and any wheel marking or drawing.
