RPM-MPH-tire and wheel size

As initiated by a Speed and RPM post;

This has the potential to be a productive thread, if we could post tire size and manufact. just to get relative ideas.I know my SO2'poles are off. I'll start with the Porsche Owners Manual chart pg. 104, 911 Carrera.

Gear # 2 @ 3,000 RPM= 30MPH,
Gear # 3 @ 3,000 RPM= 47 MPH,
Gear # 4 @ 3,000 RPM= 58 MPH,
Gear # 5 @ 3,000 RPM= 72 MPH,
Gear # 3 @ 4,000 RPM = 62 MPH,
Gear # 4 @ 4,000 RPM = 75 MPH,
