Road speed in each gear at a chosen RPM, from your ratios and tyre size.
Tyre size sets rolling circumference; add the final drive ratio.
Comma-separated, first gear to top.
Usually the rev limit - see the speed each gear reaches at that RPM.
For each gear, wheel RPM = engine RPM / (gear ratio x final drive), and speed = wheel RPM x tyre circumference. Enter your rev limit as the RPM to see the speed each gear tops out at.
On many cars top gear is geared for economy, so the engine runs out of power before it hits the limiter - the car is drag-limited, not gear-limited, in that gear.
A taller tyre travels further per turn, raising the speed at any RPM and lowering the engine speed at a given road speed.
