what does the black vertical line in the graph shown indicate? 12 oclock point equivalent rfv peak runout tread depth limit
Answer
Brief Explanations:
In tire - and - wheel assembly radial runout graphs, the black vertical line often represents the 12 o'clock point. This is a common reference point for measuring runout. Equivalent RFV is not indicated by a simple vertical line like this. Peak runout would be the highest point on the curve, not a vertical line. Tread depth limit is not related to this kind of vertical line in a radial runout graph.
Answer:
12 o'clock point
