I’d be surprised if that’s really what Grant said, as it’s not true. All gear inches charts make an assumption about wheel diameter (or radius). Wheel diameter is a function of both the rim size and the tire size. What might be true is that the assumed wheel diameter for the chart isn’t the same wheel diameter on your bike. The only gear chart that would not account for wheel size would be simple ratios.
